best power supplies for mining: ultimate guide

When it comes to building a mining rig the power supply is one of the most important hardware components that shouldnt be considered lightly. Making sure you get the best power supply for mining cryptocurrencies will ensure the longevity and stability of your rig. Obviously getting a power supply with enough wattage is a major factor but there are other important aspects to consider.

Here at Crypto Miner Tips, we know firsthand how confusing it can be to figure out which power supply to buy. Therefore, we wanted to create this guide to help you find the best mining power supply to fit your needs. In this guide, we will show not only the best mining power supplies to get, but also how to properly size your power supply (PSU) as well.

However, before we begin let us cover some mining basics that will help decide what maximum size power supply you can safely run on your outlet. Also, be sure to stick around to the end where we reveal our favorite mining power supply of them all.

Before you even think of buying a mining power supply, its always best to examine the rating of the circuit breaker your planning on using to power your mining rig. This will save you a ton of time and allow you to know what you can safely operate without tripping a breaker or even worse, cause a fire.

According to the National Electrical Code (NEC), it recommends that a circuit be loaded no more than 80% of its total wattage capacity. Here in the US, the standard wall outlet is rated at 15 amps on 120 volts. To calculate this, we can take the (amps X volts) X 80% to determine the circuits max load. This means a 15-amp breaker can safely run no more than 1440 watts total.

Most mining rigs, depending on the build, will use somewhere around 850 to 1100 watts total. This makes mining on a 15-amp breaker doable however keep in mind of anything else thats running on that same circuit. To determine the wattage of any appliance you will need to multiply the amps by the line voltage or try to google search the wattage specs of the other items on the circuit.

So now that we got some basics out of the way, its time to figure out what size mining power supply to get. This can easily be determined but will vary depending on the type of mining rig build you have in mind. A large mining rig with several GPUs will require a higher wattage PSU vs a smaller rig with just a few GPUs. Therefore, its important to calculate the total power consumption of the rig before trying to establish which brand to purchase.

Additionally, its important to note its never a good idea to load your mining rigs power supply at 100% of its capacity. Doing so can cause your PSU to deteriorate prematurely and may cause other components of the rig to fail as well. As a rule of thumb, it best to leave a 20% margin in case of surges or power spikes that commonly occur in GPU mining.

Its also wise to consider the other components of your mining right, such as the CPU, Motherboard, Ram, and Hard Drive will add an extra 250 watts of consumption. Furthermore, the coin you plan to mine will also vary in terms of power consumption. However, lets not forget that overclocking the GPUs is a must and will help lower power consumption as well.

The good news is there are tools like whattomine that can give you an overall idea of what each GPU will consume for each coin you plan to mine. From there, you can multiply the number of GPUs you plan to run and add in an extra 250 watts for all the other components plus the 20% margin. See whattomine GPU power consumption table here and follow the example below.

As you can see the 1660 Ti uses around 90 watts on most coins with a few around 100 watts. If were to plan on building a 6 GPU rig, we would factor the GPUs to use around 540 watts on the low end and 600 watts on the high end. Plus, our 250 watts on other components bring us to a grand total of 800 watts on the high-end just to be safe.

Once we factor in our 20% margin, we can clearly see that we need at least a 1000-watt mining power supply to meet our demand. However, this leaves no room to ever expand whereas if we went with a 1200-watt PSU we d have room for two more cards later if we wanted to scale.

The efficiency rating of PSU is a measure of how efficiently a power supply can convert electricity from AC to DC. Meaning an 80 plus rated 1000-watt power supply with an 80% efficiency will need to draw 1200 watts from the wall to produce a true 1000 watts. Therefore, the other 200 watts get wasted in heat and will not be used to power the mining rig. We recommend trying to go with a minimum gold 80 plus rated for max performance and efficiency.

Getting a power supply with an excellent warranty is a must. Here at Crypto Miner Tips, weve experienced only one PSU failure out of all the mining rigs we have. Thankfully, the mining power supply was under warranty still after 3 years and got it replaced with no questions asked. There is a saying that good things aint cheap and cheap things arent that great. We recommend going with a power supply that has at least a 2-year warranty but some even have a 10-year warranty as well.

When building a multi GPU mining rig you will need to power them with mining risers. Each riser will need either a 4 pin Molex or 15 pin SATA cable to power it. This is important as you cant really mine efficiently without them. Thats why we recommend going with a power supply that comes with enough ports and cables to meet your mining rigs needs. While were on the subject of cables, its worth a mention that its unwise to mix cables from different models of power supplies as they have different ratings, and some are even incompatible.

Ok, so we understand there are other more affordable options when it comes to mining power supplies, such as server style PSU. While we could recommend them here in this guide, to us, they are not the best option and heres why For starters, ATX style PSU offers better surge protection to protect your other components. Furthermore, server style ideally needs to run on 240v to get the most out of them. Not to mention if youre not careful in the way you turn them on and shut them off you can run the risk of shorting out your motherboard. Therefore, we recommend sticking with the ATX style PSU. Oh, and server style fans tend to be noisy.

UPDATE: Mining profits have gone up significantly since the time of writing this guide which is causing a server shortage of mining hardware. Use this link to find server power supplies in stock Parallel Mining at affordable prices.

Alright, so now that you know how to properly size a PSU for your mining rig needs, time to reveal our list of best power supplies for mining. Honestly, this was a tough decision to do as we could have recommended a lot of different models here. However, we stuck with what we personally use for the most part. If you have any questions about mining power supplies or need further assistance, dont hesitate to join our FB group for help.

We personally use these for our 6 GPU 1080 Ti mining rigs and have had no issues whatsoever over the past three years. One thing that we really like is the fact it comes stock with enough cables to meet most mining rig needs. Another great feature is the fact that this model is backed by a 10-year warranty which to us is huge.

However, when it comes to price this model does tend to run a little on the high side of the market, however, we truly believe its quality cant be beaten. The fans on this model are very quiet and durable as well. All in all, this thing is a beast when it comes to power a mining rig and suits most miner needs.

Another leader in the computer power supply industry is corsair which has several series of power supplies in addition to the HXi models. The Corsair HX1200i, power supply is an 80 plus 1200-watt platinum rated and has 90% efficiency at real-world load conditions.

Weve used quite a few of these on our 8 GPU 1060 6gb and 6 GPU RX 580 8gb rig builds and couldnt be happier. This model comes with more than enough cables to fit most mining rig builds needs. The Corsair HX1200i is also equipped with surge protection that is unparalleled to most of the other mining power supplies out there.

If we had one gripe to complain about this model is the fact that the cables are a bit bulky which makes cable management a bit of a task. However, thats trivial to us considering its price is low when compared to other models out there.

The EVGA SuperNova 1200 P2 power supply is yet another popular option for building a powerful mining rig. This is a 1200-watt platinum-rated power supply that offers a 10-year warranty as well. Its built with the same award-winning technology from EVGA other P2 and G2 models and is 92% efficient at 110 volts.

This model is fully modular to make your mining rig look uncluttered. It comes with 6 VGA connectors for a total of 8 8-pin connectors to power your graphics cards. It also has 2 Molex cables and 4 15-pin SATA cables for a total of 12 connections which ensures enough cables to power your risers and SSD. Finally, it has a 14-gauge power cable for max performance.

Again, when it comes to price you might pay a bit more but considering EVGA 10 warranty for this model can make it a great option. We would recommend this as a mining power supply for most 6 to 8 GPU mining rig builds.

The EVGA SuperNOVA G3 is yet another popular option that offers an 80 plus gold 1000-watt power supply. This model has all the same great features as the award-winning G2 series but with a smaller form factor. The efficiency is on par as well with it being 90% efficient on 120 volts.

This model also comes with EVGA outstanding 10-year warranty like most other models. As far as cables go this model would be great for a 4-6 gpu mining rig build depending on your GPU model. However, if you need more power you could buy a 24Pin ATX PSU Y Cable 24 pin Splitter Power Cable run two of these in unison for added performance.

When it comes to price this is one of the cheaper models to go with that doesnt sacrifice much performance. The 850-watt model in this series would be a great option as well if you wanted to build a 2-3 GPU cross-functional gaming/mining rig. EVGA FTW!

The Corsair AX 1200i is Corsairs flagship power supply that offers an 80 plus platinum-rated 1200-watt power supply. This model is fully modular like most models and immense efficiency of 89% while under 100% load which is impressive.

This model also comes with a lot of cables to suit most 6 GPU and even some 8 GPU mining rig builds. However, its price is a tad on the higher end of the spectrum of what you might consider but it makes up for it with a full 10-year warranty.

Honestly, weve used this model on quite a few of our mining rig builds and have had no complaints other than price. However, the stability and little downtime on our rigs have made this PSU a purchase worth every penny.

Out of the mining power supplies listed here, the EVGA SuperNOVA 1600 P2 is the best of them all. This power supply is 80 plus platinum-rated with an impressive 1600 watts and 92% efficiency on 120 volts.

When it comes to quality cables there is no shortage of them with this model. This mining PSU can power most 8 GPU mining rigs with no problems. In fact, we use these on our 8 GPU 1070 8 GB mining rig builds and have been quite happy with the performance.

However, this is one of the bulkiest and heaviest mining power supplies ever so keep that in mind when you are choosing a mining rig frame. All in all, the power output on this is exceptional and yes it comes with a 10-year warranty as well. You might pay a premium for this model but the quality you get is worth it to us.

So now you know what some of the best power supplies for mining are, but youre still wanting to know what we would recommend if we were to choose one model. When it came to this decision, we want to include price as a factor as well, so here is our top pick mining PSU.

The Corsair 1200 HXi is our number one pick out of all the ones listed here. Weve used this PSU in most of our GPU mining rigs and couldnt be happier. The fact is youre not going to find much other quality platinum rated PSU at the same price as this one while still offering a 10-year warranty.

Furthermore, when it comes to having enough cables this model will fit most mining rig builds needs which to us is important. Honestly, this was a tough choice between this model and the EVGA SuperNOVA 1300 as its one of our favorites as well.

In the end, there are many other great models as well from EVGA and Corsair that we could have shared here which will work for mining cryptocurrencies. The most important factor is properly sizing one to fit your needs.

best psus for crypto mining: reliable power supplies for ethereum, bitcoin | tom's hardware

Cryptocurrency Mining has become extremely popular again lately, with many people looking to optimize their existing GPUs for mining or looking to buy the best GPUs for mining. Some are even wondering how to mine on a Raspberry Pi. No matter what currency you go for, the market is extremely volatile and the costs of electricity and hardware are prohibitive for many people. You could end up losing a lot of money while dramatically expanding your carbon footprint.

But if youve made the decision to mine with your PC, you need a powerful and robust power supply to keep the current flowing to your graphics card(s). While we maintain a list of the best PSUs for gaming, the qualities you should look for in a mining power supply are a little different.

While its not required, its good to have a PSU that comes with a minimum one-year warranty that covers 24/7 operation under full load at 30-35C. That way, if your PSU gives out within the first 12 months, you can recoup your investment.

The most important requirements involve efficiency and build quality. For maximum endurance and performance, we recommend using your PSU with 230V input whenever possible. Besides 1-2%-higher efficiency, this also reduces the amperage passing through the AC power cord by half, reducing stress on the cable. If you live in a region with 115V mains and can afford the installation of 230V sockets in your home, use them for your mining ventures.

Thermaltake Toughpower PF1 750W Platinum: This high-performance power supply from Thermaltake doesn't make it to the list because it doesn't have an MOV in its transient filter. If you combine it with a surge protector, you will solve this issue. Connectors: 2x EPS, 4x PCIe

Based on our testing, we have a table of recent-generation GPUs and approximately how much power they use while mining. You might be surprised to learn that they dont necessarily need to use their peak power while mining because they dont need to maintain maximum clock speeds to get good mining performance.

Many miners underclock and undervolt their graphics cards to keep the stress and power consumption as low as possible. This allows even smaller-capacity PSUs to power a pair of high-power GPUs without any issues. For maximum efficiency, you should keep the load at around 50-60% of the PSUs rated capacity so a 1,000W PSU should be using no more than 600W if possible. Keep in mind that the numbers below are only for the GPU and do not include other components such as the CPU, storage drives, RAM, cooling and motherboard.

5 best power supplies for cryptocurrency mining in 2021

5 best power supplies for cryptocurrency mining in 2021

Cryptocurrency has really established itself as a cornerstone of the modern internet in todays world. As of the time of writing, Bitcoin has crossed over $60,000 in value and is on an upward trajectory going forward. This means that Cryptocurrency mining has become really popular in the current scenario. Mining requires a lot of computing power that is usually provided by multiple graphics cards that work in tandem. Extensive crypto-mining farms have been established that use the power of dozens and even hundreds of graphics cards at a time to maximize the profitability of mining Cryptocurrency.

However, graphics cards are not the only components that are necessary for a crypto-mining rig. Of course, you also have to provide lots of clean and stable power to those graphics cards, and that is where the power supply comes in. Since crypto-currency mining PCs and rigs have a lot of graphics cards in them, they often require really powerful power supply units that can handle multiple graphics cards operating at their maximum load capacity. For this list, we will be taking a look at power supplies that are designed to be used in desktop computer systems, and not the units that are purpose-built for mining rigs.

Corsair is one of the most reliable PSU brands on the market right now. Most of Corsairs PSUs are actually manufactured by Seasonic which is arguably the best OEM for power supplies right now. Nevertheless, Corsairs PSUs are excellent due to their high-quality components, robust operation, and reliable lifetimes and the AX1600i is definitely no exception. The Corsair AX1600i is an extremely premium PSU that can handle just about anything you can throw at it.

The AX1600i has a total capacity of 1600 Watts which is ridiculous overkill for any normal gaming rig, but it might not be completely unreasonable for a mining machine. Ideally, power supplies should be operating at 50-60% load to deliver maximum efficiency according to the efficiency curve. Buying a powerful 1600 Watt power supply would ensure that even with multiple graphics cards under load, your power supply would be operating at its peak efficiency most of the time, and that can really maximize your profits by lowering power wastage.

Another strong point of the Corsair AX1600i is its 80+ Titanium efficiency rating which is the highest efficiency rating given to consumer power supplies. This means that the AX1600i is one of the most efficient power supplies on the market while having one of the highest capacities as well. Corsair has positioned the AX1600i to be a no-compromise solution for gamers and professionals who need a robust, premium power supply for their power-hungry components, and that works out in the favor of Cryptocurrency miners as well.

In addition to having 1600 watts of capacity and an 80+ Titanium rating, the Corsair AX1600i can provide up to 133.3A of current on its 12V rail which is more than enough for multiple graphics cards working in tandem. In fact, the AX1600i can handle around 6-8 units of AMD Radeon RX 480 graphics cards quite easily by using only a single unit and that is a truly remarkable feat of engineering. Of course, this is helped further by the inclusion of ten 8-pin PCIe connectors that can deliver all that power to the graphics cards of choice.

While it is true that the AX1600i is one of the most powerful consumer desktop power supplies on the market, it does have a major drawback and that is the price. Even the remarkable 10-year warranty cannot distract you from the truly astronomical price of this unit. However, for those of you who are looking for the best of the best, the AX1600i is definitely the power supply to buy for your mining rig.

The Corsair HX1200i is another one of Corsairs premium high-wattage power supplies but this unit comes from the slightly older HX lineup. However, that does not mean that the HX1200i is not a worthy competitor in todays market. In fact, the HX1200i is still one of the most premium power supplies in the consumer desktop space in 2021, and one can safely assume that it will continue to be for quite some time.

Compared to our top pick, the AX1600i, the HX1200i drops the total capacity of the unit to 1200 watts instead of the 1600 watts of the former. 1200 watts is still more than enough more multiple graphics cards working together in a reasonably powerful crypto-mining rig. The 1200 watt peak capacity of the HX1200i still allows it to operate in the peak efficiency window of 50-60% when several attached graphics cards are operating under load.

The HX1200i also drops down a bit to the 80+ Platinum category, although calling that a downgrade would be a bit of an exaggeration. The 80+ Platinum efficiency is only awarded to extremely premium PSUs that deliver exceptional efficiency numbers under a variety of load scenarios. It might not be as efficient as an 80+ Titanium PSU, but it is as close as one can get to 100% efficiency without completely breaking the bank.

The single 12V rail of the HX1200i is capable of carrying 88A of current which is ample for multiple crypto-mining graphics cards working in tandem. The HX1200i can deliver this power to those graphics cards through its 8 available 8-pin PCIe connectors. All these features make the HX1200i finely equipped to handle many graphics cards simultaneously, and thus make it perfectly suited to a crypto-mining rig.

All in all, the HX1200i is one of the most premium high-wattage power supplies currently available, and it is one that makes quite a bit of sense if you are looking to establish a small crypto-mining rig. It is not as over-the-top as the AX1600i but it can deliver essentially the same features at a much more reasonable price. The only downside is its relative age, which should not pose a problem unless you opt for the used market.

Seasonic is one of the finest power supply brands on the market and they serve as an OEM for many other PSU brands as well, such as Corsair. The premium units from Seasonic use extremely high-quality components that allow them to perform reliably over a long period of time, and the Focus Plus 1000 Gold is no exception. The Seasonic Focus Plus 1000 Gold is one of the more reasonable all-round choices in our list due to its competitive price tag and high-quality components and features.

The Focus Plus 1000 Gold is has a maximum wattage of 1000 watts which is enough for 2 or 3 cards working together in a mining rig. This PSU is best suited to mid-range or older cards that have lower TDPs as compared to modern cards such as the RTX 3000 series. The PSU should be able to handle 2 to 3 RX 480 or RX 580 graphics cards at once, and that can deliver decent crypto-mining performance without completely breaking the bank.

The efficiency rating is also a bit lower than the Corsair units mentioned before, but 80+ Gold efficiency is certainly nothing to scoff at. The 80+ Gold standard certainly puts this unit into the high-end premium category, and also makes it a bit more affordable than the Platinum and Titanium units. The Seasonic Focus Plus 1000 Gold makes compromises in the right places and bumping down the efficiency to 80+ Gold is one of those places that makes the most sense.

The PSU can deliver up to 83A of current on its single 12V rail and that is unexceptional if we compare it to other PSUs in the same category. However, this should certainly be enough for 2-3 midrange cards working in tandem in a small mining operation, and that is exactly what this PSU is best suited for. The Focus Plus provides six 8-pin PCIe connectors to provide this power to those cards, and it is backed by a 10-year warranty as well.

While it may not be the highest-end PSU by numbers and specs, the Seasonic Focus Plus 1000 Gold is one of the most reasonable choices for a mining PSU right now. It has enough wattage to handle a small mining operation, and is reasonably efficient as well while costing quite a bit less than the more premium options. The only reason to get the more expensive units would be if you are looking to establish a slightly bigger mining operation with more graphics cards.

EVGA is another brand that is known for producing some high-quality, reliable power supplies. Their offerings range from ultra-budget units all the way up to extremely premium units that can handle multiple graphics cards at once. The EVGA SuperNova 1000G+ falls into the latter category as it is also one of the best PSUs that EVGA currently has for sale.

Just like the aforementioned Seasonic Focus Plus Gold, the EVGA SuperNova is a 1000 watt unit which is plenty of wattage for 2-3 graphics cards of reasonable power draw. This can be ideal for those of you who are looking to establish a small mining rig with a few cards that you might already have. Moreover, the PSU can also handle some modern cards like the RX 6000 series and the RTX 3000 series, provided that you only plan to use 2 of them in one machine.

EVGA has gone with an 80+ Gold efficiency rating which is also really solid for a PSU of this quality. Of course, it is not as efficient as some of the Platinum or Titanium-rated units out there, but 80+ Gold can certainly get the job done nicely. This PSU delivers up to 83.3A of current on its single 12V rail, which is good enough for a small mining configuration with 2-3 graphics cards of reasonable power draw. EVGA has provided six 8-pin PCIe connectors to deliver that power to the graphics cards of choice.

Backed by a ten-year warranty, the EVGA SuperNova 1000G+ is certainly a solid power supply for a Cryptocurrency mining rig in 2021. The unit is comparatively more affordable than the ones with higher efficiencies and higher wattages, but it does not compromise on the quality and the reliability of internal components. Along with the Seasonic Focus Plus, the SuperNova 1000+ is the most reasonable option for a crypto-mining PSU that offers a good price-to-performance ratio without breaking the bank.

The Corsair RM850x is one of the most popular consumer desktop power supplies on the market. This PSU belongs to the highest class of desktop power supplies and has certainly become a fan favorite among PC building enthusiasts. The RM 850x is the most popular variant of the RMx series from Corsair due to the excellent quality of its internal components and top-notch reliability.

While the RM 850x might be a solid unit for consumer desktop gaming PCs, the same cannot be said easily for mining rigs that have multiple graphics cards. In fact, the RM 850x should not be bought if you want to run 4-5 graphics cards in a moderate mining operation. This PSU is ideal for those who already have a gaming PC with this incredible unit inside, and they want to take advantage of their machine for some mining on the side. This PSU can handle a modern, fairly powerful graphics card quite easily, or you can take advantage of two graphics cards with lower power consumption for a similar experience.

The reason for this exclusive case is that the RM 850x is aimed at gaming PCs and not at mining rigs. It only has 850 Watts of total capacity, which is barely enough for one RTX 3000 series graphics card. Alternatively, you can use two older graphics cards that are less powerful, but that is the extent of the capabilities of this PSU. It is rated 80+ Gold, however, and that is certainly a nice touch. Corsair has also provided six 8-pin PCIe connectors with the RM 850x, and it is backed by a 10-year warranty as well.

The Corsair RM 850x is not a unit you should buy specifically for a mining rig. This is a very high-quality that is preferred by many high-end gaming PC builders, so it is already a common PSU among enthusiasts. If you already have this PSU in your gaming rig and want to do some light crypto-mining on the side with one or two graphics cards, then the reliability and durability of the RM 850x will not let you down.

using dual power supplies for mining - the geek pub

Mining. Youre probably sick of hearing about it! But its in the news. Its on TV shows. Its all over blogs. Well, not mining specifically, but cryptocurrency. Specifically a certain type of cryptocurrency called Bitcoin. To mine bitcoins you need an ASIC powered miner. But for many other cryptocurrencies like Ethererumcan be mined with GPU cards in regular computers. It didnt take long for people to figure out that you could put 3, 4, 6 or even 12 GPUs in a single computer using PCIe risers. This led to the need for massive power supplies in the 1500 watt range or more. That is until someone figured out a way of using dual power supplies for mining!

When you stack multiple GPUs in a mining PC you start to use a lot of power very fast! In some cases a single GPU can eat up 200 watts of electricity. However, in most mining PCs the GPUs will only use around 160 watts. Even still, 160 watts multiplied by six is 960 watts. Add a motherboard, risers, CPU, hard disk, networking adapter, etc. and it doesnt take long to blow past 1100 or 1200 watts.

This can be very frustrating for new miners. Not only can a 1200+ watt power supply be very expensive, they can also be very hard to find in-stock. I have a list of the best power supplies for mining rigs you can read up on for more information.

Modern ATX motherboards actually control the power supply. This feature can make it difficult for using dual power supplies. Two of the pins on the ATX power connector turn on and off the power supply. If only one power supply is connected to the motherboard the other power supply wont ever turn on (or even know how) when the motherboard activates the PSU power relay.

To solve for this, some really creative guys came up with an ATX power cable that splits that relay signal into to cables. Just plug both power supplies into this cable and then plug the cable into the motherboard. This fires up both power supplies when the motherboard power button is pressed. These are safe, reliable and a simple way to use dual power supplies. However, be sure to read the risk section below.

Another great option that becomes exceptionally handy is a power supply sync module. The sync module works by connecting to a SATA port on your main power supply. When it senses power is applied, a relay engages the power pins on the second power supply.

This is incredibly handy for use with three or more power supplies in much larger rigs (12 GPU rigs). You can plug as many of these into your main power supply as you have SATA ports available, and then plug the rest of the power supplies into the ATX headers on the the sync modules. Pretty sweet idea!

The problem is that the power between the to power supplies is not isolated. This can be very problematic for circuitry in your computer, especially if the power is out of phase. If you have dual power supplies plugged into different outlets in your house, they may be on a different phasing from your breaker panel. The can wreak havoc on your PCs internals.

To solve for this you need to make sure components only receive power from one power supply. For example, plug the ATX power connector and the CPU power connector to the motherboard from power supply one only. On power supply two, make sure the VGA power connector and riser power both come form the same power supply.

Never plug the riser into power supply one, and the GPU into power supply two. This can be an easy mistake to make if youre not paying attention! Try as much as possible to spread the load across both power supplies evenly.

This is so much win! I had no idea you could run power supplies in tandem. Ive been looking everywhere to find a supply big enough for my miner, but this totally solves the problem. I do have one question though. How do you know if the wire is big enough since the wattage is different on power supplies? Is there one specific for a specific watt supply or what?

The wattage number on the power supply is for the total wattage of the unit. Each modular cable has a fixed wattage. Higher wattage supplies have more modular ports, not a higher wattage per cable (generally though there are a few exceptions that dont apply to this).

Question: All GPUs and risers dont need to be on the same PSU just each pair (GPU and associated riser) need to be on same PSU, correct? So I could have 3 GPU/Riser pairs on one PSU and 3 GPU/Riser pairs on another PSU?

how to choose the best psu for a multi-gpu mining rig - crypto mining blog

how to choose the best psu for a multi-gpu mining rig - crypto mining blog

It seems that still a lot of people may overlook the importance of the power supply when building a multi-GPU mining rig and the more the number of video cards, the more the issues may arise. Normally people think that if you have six video cards with a TDP of 150W, then any decent 1000W power supply should be just fine for the job in providing enough power for the mining rig. Doing the simple math it will, however when we get to actually connecting everything things may actually start to get messy. You might discover that you have not properly planned the number of power connectors you need for the video cards that you need, or the number of 4-pin Molex connectors needed for the powered risers. The simplest solution here would be to just add some splitter adapters and got a few extra connectors available to be able to just connect everything. Unfortunately the simplest solution here is definitely not the wisest thing to do as you might end up overloading some of the wires going to the PSU

The first thing you need to ensure is that the power supply you go for has enough PCI-E power connectors available to power all of your video cards in the mining rig. So if you have 6 video cards getting six separate PCI-E power connectors from the power supply is the best solution. Unfortunately not many power supplies are designed with single cables for 6 or even more PCI-E power cables as normal computers rarely have more than 2 or up to 4 video cards in rare cases. Even if a power supply has let us say 8 power connectors these are usually double connectors going from a single wire to the PSU and this is originally designed for up to 4 video cards (if they have double PCI-E power connectors). Adding additional adapters splitting single PCI-E power connector to dual PCI-E or using Molex to PCI-E power adapter can cause problems, so if possible it is wise to try and avoid it. If not, then you at least need to make sure that you are not overloading any of the lines going to the power supply, the easiest thing to check for that is to touch the cables and if they are getting hot, then it is not Ok.

If you are using a motherboard with multiple PCI-E slots like the AsRock H81 Pro BTC motherboard that is actually designed to be sued for GPU mining rigs you will need to use extenders. Although the motherboard has extra 4-pin Molex power connectors in order to properly power video cards that need more power from the PCI-E slot. Even in this case it is still better to go for powered PCI-E risers and do not try to draw more power through the motherboard, especially if you go for 6 GPUs. The x16 PCI-E slot that is normally being used for video cards on the motherboard is designed to provide up to 75W of power to the video card by specifications, though most of the consumption comes from the 12V line and there the max power is rated at up to 66W. If you however have 6 video cards that are maxing out the power draw from the motherboard it will come up to a pretty high number, even though in most cases video cards do not go with the maximum power that the PCI-E slot can provide them with.

There are a number of different PCI-E risers, but one that is very popular choice is the x1 PCI-E to USB 3.0 riser as it is really well designed and works very good, unlike the case with not so well made ribbon cable extenders. These risers use a USB 3.0 cable, but they are not actually using USB interface, the cable is just a good choice for the data communication without issues. PCI-E risers like the one on the photo rely on 4-pin Molex power connector to supply any power that the video card may need, completely cutting any power draw from the motherboards PCI-E slot. We already know that the video card can draw up to 66W over the 12V line and this should normally not be a problem for a 4-pin Molex connector as these connectors are rated at 10-11A per wire and since there is just one 12V wire you should in theory be able to go for up to 120-132W over it, but that is only if you have a single Molex power connector.

The actual problem with 4-pin Molex power connectors are not the connectors themselves, but the cables that are being used to route them to the PSU, because they also have a maximum power rating depending on their thickness. Power supply manufacturers and cable adapter manufacturers do not go for the best option as it would make things more expensive and in most cases it will not hurt to go for a thinner cable. To be able to get up to 10A current over a 4-pin Molex connector you would require a 14 AWG or 16 AWG wire, 18 AWG ones are rated at up to 8 Amps and 22 AWG wires are rated for up to 6 Amps. Unfortunately most manufacturers do not go for 16 AWG let alone for 14 AWG wires on Molex connectors (usually 16 AWG wires used on PCI-E power connectors on high-end power supplies). In most cases the power supply wires for the 4-pin Molex connectors are 18 AWG, though there are cases, especially for adapters or extenders where even cheaper 22 AWG wires are being used.

If the maximum power draw for a video card over the 12V line of a PCI-E slot is 5.5A (66W) then even a 22 AWG wire rated at 6 Amps should be enough. It should, but only if you connect only one such 4-pin Molex power connector to a line going to the power supply. That is rarely the case however as power supplies normally have a couple such 4-pin Molex connectors on single line going to the power supply and that goes over a 18 AWG wires. In order to be safe a maximum two PCI-E extenders should be powered by such cables to stay within specs or at least close to them, but people often use three or even four of these connected and that can lead to cables overheating and melting or even burning and damaging your expensive mining hardware as a result.

Normally with video cards that have external PCI-E power connector the maximum of 66W over the PCI-E slot is never reached, it will be more like up to 30-40W for example (or less), though there are exceptions as well the reference design Radeon RX 480 GPUs. Even at 40W if you connect three or four of the 4-pin Molex power connectors that use a single cable line to the power supply, then you will still be over the maximum rating of the cables. What happens is the cables starting to heat up and as a result they may even melt and short out and that can do things like start a fire, damage your video cards, motherboard or power supply etc.

The easiest way to discover such a problem is to just touch the power cables a few minutes after you have the mining rig up and mining, so that it is under heavy load and using a lot of power. Cables that are hotter to the touch than the others are probably near or over their limit and you should think of a way to reduce the power draw over the specific power line to the PSU. If you have a thermal camera you can just take an image like the one above and see the problem clearly and diagnose which cable might be overloaded and do something about it. But even if you dont have extra tools to assist you, even just touching and noticing a hotter cable can be enough to find an issue with the power distribution of your mining rig. Do not overlook possible issues like that as later on they may cause you serious headaches and even cost you a significant amount of money, taking you on the red, instead of you actually making profit from mining.

It is not that simple, like h81 pro btc need 24 pin, 8 pin and 2 molex, and for powered risers you need 6 molex, and each powered risers need more than 75W withnew amd cards, so all need be on separate line How to grounded 2 or more psu? How to calculate and distribute psu to cards There many questions

@vic You can use h81 pro btc without connecting molex to mobo. You must use powered risers though. I use 6x powered USB risers, no molex to board (need to press N I think to ignore mobo warning on startup). The risers are powered by molex, or via sata to molex adapter (be weary using sata adapter on reference rx-480s, any 3rd party design will be fine, especially ones with 8 pin pcie connector).

best power supply for mining cryptocurrency - the geek pub

best power supply for mining cryptocurrency - the geek pub

When building a GPU based mining rig, research shows there is a lot of misinformation going around that makes it difficult to decide what to purchase. This has a lot to do with the nature of mining. Its something that just about anyone with a little cash can do, if they can follow directions from a blog like The Geek Pub. These people post in forums and all over the internet in blog comments. In many cases their opinions and advice are simply uninformed at best, and blatant lies at worst. Choosing the best power supply for mining cryptocurrency on a GPU is one of the areas where this becomes clearly obvious. Youll see chants of You need multiple power supplies. or You need a 2000 watt power supply. Read along and well get to the bottom of this quickly!

Its very common to think that a GPU miner needs massive amounts of electricity to operate. And it is true that it needs a lot. Its also true that there is more than meets the eye when thinking about power supply wattage numbers. Indeed the power supply might be one of the most critical components for a mining machine, right next to the GPU itself. Heres the good news: This is mostly a simple math equation that anyone can do.

The first thing you need to do is understand the total wattage that your mining computer will draw. Add up the wattage of all of the components in your rig and see where that final number lands. The main concerns here are your processor, motherboard, and GPU cards. This however is where things can get really confusing. The wattage number on your processor is likely to read something as high has 95 watts, while the number on a card such as the NVIDIA GTX 1060 is likely to read as high as 200 watts when looking at the manufacturer specifications. With six GPUs youre looking at 1295 watts!

Heres where much of the confusion comes in. These are the maximum theoretical wattage numbers, under a perfect condition and full load. In your mining operation there is almost zero chance you will ever hit those numbers. As shown in the tour of my mining PC build, I run six GTX 1060 cards, each pulling about 95 watts at maximum load.

Mining doesnt use the full capacity of the card or even many of its components. Think about it. There are many components on the GPU designed to deliver video to a monitor. None of these components are even connected in mining operations. Much of the data bus of the card is idle most of the time. Its the CUDA cores that are busy calculating hashes for the coin you are mining.

While we overclock the memory core of the GPU, we under-clock just about every other component on the card. The core GPU clock can be under-clocked as much as -200 Mhz depending on the card. The power levels can be set as low as -65% on some cards. Other cards can be under-volted with literally no impact on performance.

These factors result in a GPU rated at consuming 200 watts at maximum theoretical load actually consuming only 95 watts during a mining operation! This is great news because your six GPU mining rig that calculated at 1295 watts, in actuality is only pulling about 520 watts in a mining operation. This same thing applies to almost every component on the board. That 95 watt CPU is likely only consuming 15 to 20 watts at idle (or mostly idle).

The world is over-subscribed. This is something many people miss completely and one of the reasons there is so much bad advise going around on the internet. It makes it really hard for the uneducated newbie to pick the best power supply for mining cryptocurrency. You will literally see people in the forums say But your mining rig might surge and youll burn out your power supply. This is utter hogwash.

Walk out to your garage or go in your basement and look at your breaker panel. It probably says something on it like 200 amp panel. A 200 amp is the most common panel installed in residential homes. The main breaker at the top of the panel will be a 200 amp breaker. This feeds the entire panel. Now take just a minute to add up all of the breakers in the panel. What? They add up to more than 200 amps dont they? Thats nuts! Actually its called over-subscription. Your power company does this. Your Internet company does this too. I can assure you AT&T doesnt have a terabit uplink to cover the 1000 gigibit connected homes in a a Gigapower neighborhood.

Thats because they know the odds of everyone doing something at once is infinitesimally small. The same thing is happening inside your mining rig! One card may surge for a second, the CPU may surge for a second, etc. But not all at once.

There is a good reason to over-size your mining power supply though! And that comes in the terms of efficiency. A power supply performs most efficiently when running at about 80% load. This allows the fans to spin down, and the the power supply will generate less overall waste heat. Slightly over-sizing your mining power supply can save you some cash on your electric bill resulting in a more profitable miner, assuming you dont spend so much on the supply as to eat those savings. If your rig tops out at 520 watts, spring for 850 watt supply to keep things efficient and give some wiggle room.

Another thing to consider is getting a smart power supply. This is two fold. Mining rigs usually operate unattended without a keyboard, mouse, or monitor attached. Being able to remotely monitor the power supply wattage and temperature levels is a great feature to have. Additionally, as you add components to the rig over time or upgrade older components you can make sure you are still within the limits of your supply. Some manufacturers report this data through a protocol called LINK. Smart power supplies will add a little cost your ROI equation, but in my opinion not enough to outweigh the benefits.

Another great feature to look for in a power supply is modularity. A fully modular power supply means that the cables are not permanently attached to the power supply. This allows you to use different cables for different components. If you dont have a certain component on your rig there is no cable hanging loose and unused that needs to be dealt with. Simply leave that cable in the box for future use.

Modular power supplies generally come with multiple cables for different types of devices. This means you can select exactly the modular cable (and number of cables) you need to build out your rig. I always recommend a modular power supply when you can afford one.

So lets list my top 4 picks for the best power supplies for mining! These power supplies should work in 99% of mining rigs being built today. If you are planning to use a super power hungry card like a Titan V, then more planning is likely required. Check out my article on selecting the right mining GPU for help. Also, understand you have the option of using two smaller power supplies in a dual power supply mining rig.

The Corsair HX1000i is a 1000 watt smart power supply with LINK technology. Its incredibly quiet, super efficient, and has plenty of modular ports for running PCIe risers, GPUs, and just about anything else you need it to.

Rocking in at number two on our list of the best power supplies for mining is the EVGA SuperNOVA 1000 G2. This power supply is fully modular, gold certified, and comes in at 1000 watts. What brings it to number two on our list is that it costs slightly more than the HX1000i and does not offer smart features. Get it here!

The Cooler Master V1000 comes in at number 3 on our list. Its a great compromise between these other supplies. Its fully modular, gold certified, and clocks in at great value price! Its only downside is that it is not a smart power supply. Get it here!

The Rosewill Gaming Power supply is a bronze certified power supply clocking in at the lowest price on the scale. Its perfect for the budget conscious miner. Its 1000 watts and meets the requirements of most mining rigs. It however, isnt fully modular. Youll have to deal with a giant octopus of cables hanging out the back, even if that cable is unused. Additionally it is not a smart power supply.

Not sure if you realize, but there is enough wattage on each rail to run two GPUs. Thats why there are daisy chain connections. (True only if your card requires one PCI connection that is ie. GTX 1060, wouldnt work on a 1080ti.)

Depends on the card. For the GTX 1060 it is safe to daisy chain. Those cards even include a Y-adapter in the box in case your power supply didnt have it built in. For GTX1080, no. They pull too much to daisy chain.

how to choose power supply unit (psu) for cryptocurrrency mining - coin suggest

In our other posts, we have covered topics like building mining rigs, maintaining them, etc. We have also talked about choosing graphics cards and motherboards. And in this guide, I am going to help you shop a power supply for your next mining rig.

After figuring out the power consumption you need to look for a good PSU. A good PSU usually comes with an 80 Plus efficiency rating. So I consider this another feature to look out for when shopping for power supplies.

80 Plus Platinum rating to be exact. This means that this PSU is about 92% efficient in 115V AC. And this figure goes even higher to 94% in 220V to 240V AC. So in the best-case scenario, expect the power supply to supply at least 1100 watts of power.

The fan also has an ECO mode which is helpful for reducing noise. You can turn this on with just a push of a button. But I believe it is of very low importance to a miner. As for a miner, the most important thing is the optimal power delivery.

EVGA has carried forward most of the features from EVGA SuperNOVA 1200 P2 to the 1600W model. So the 1600 P2 also features the vertical double-layer transformer, Japanese solid-state capacitors, the 140mm heavy-duty fan, etc.

If you are thinking about using this PSU for mining. You can build 6 GPU VEGA 64/56 Mining rig or 7 GPU GTX 1080 Mining Rig. I usually prefer Nvidia Cards for mining because they can do well on both the algorithms like Equihash & Ethash.

This pick is for the ultimate cryptocurrency miners who have powerful mining rigs. The EVGA SuperNOVA 1600 T2 is a 1600W power supply just like EVGA SuperNOVA 1600 P2. But the only difference is the 80 Plus rating. In the case of the P2, it is 80 Plus Platinum but in the case of T2, it is 80 Plus Titanium.

And the power supplies are not exceptions as well. I am not implying that Corsair or Seasonic power supplies are of poor quality. But when it comes to EVGA vs Corsair or EVGA vs Seasonic I will always choose EVGA.

Without a doubt, the component that takes the most stress in a cryptocurrency mining rig is its power supply. Of course, when you choose to install multiple GPUs for mining, you have to complement them with a powerful PSU or use more than one power supply to deal with the load. Given lots of demand right now, you might find the highest-capacity models out of stock. While it might be tempting to use a lower-capacity PSU pushed closer to its limit, that can lead to catastrophic results, especially since mining rigs often operate unattended. It goes without saying that mining requires a high-quality and ultra-reliable power source. Capacity and PCIe connector count shouldn't be the only factors that influence your purchasing decision. So, to help you pick the best PSU for your mining rig, we're digging deep into our comprehensive database of benchmark results to identify the top models.

A mining PC's PSU needs to have some specific features and specifications if it's to survive the job you're giving it. We're going to use the requirements set forth by Cybenetics in its Mining-Ready PSU project as a foundation for our project.

We define home miners as folks dabbling in cryptocurrency mining on the side. They don't want to spend a fortune building dedicated mining machines. Instead, they're looking for something that'll yield some profit and won't cost much. The home miner's rigs are running somewhere inside the house, subjected to reasonable ambient temperatures. Still, noise can't be allowed to get out of control.

Below you'll find our selections for the best PSUs for cryptocurrency mining, a list of our requirements and recommendations, details on the selected PSUs, and some benchmark numbers based on critical criteria. This page is for those mining at home; the following page is for professional mining.

In total, we have 15 requirements and five recommendations for PSUs used in home-based cryptocurrency mining PCs. The most important are the efficiency and build quality factors, along with capacity. Inside of a home, where this type of mining rig will operate, climate control maintains comfortable temperatures, so in most cases we accept FDB fans and their derivatives. These don't have reliability issues below 35C ambient. The fan does have to use a true FDB or high-quality rifle bearing, and not just a plain sleeve bearing. Those are the cheapest and most unreliable solutions for PSUs running 24/7.

Another recommendation is to use your PSU with 230V input whenever possible. Besides 1-2%-higher efficiency, this also reduces the amperage passing through the AC power cord by half. As a result, the cord endures much less stress. If you live in a region with 115V mains and can afford the installation of 230V sockets in your home, definitely use them for your mining ventures.

Their problem with the majority of failed PSUs has to do with the power-good signals that we measured, which are either lower than the ATX spec recommends or inaccurate (or both). Even in PSUs used for normal tasks, an inaccurate signal can prove fatal. So imagine what happens to your pricey graphics cards if the rails go out of spec and the PSU pretends everything is still good, rather than telling your motherboard to shut down immediately. Very low voltage levels will push the graphics card's and motherboard's DC-DC converters to their limits, potentially frying components. It's a shame to see such high-end PSUs reporting fake power-good signals. Although they satisfy the rest of our requirements, we strongly advise against them.

With a longer hold-up time and an accurate power-good signal, the 1.5kW Toughpower would be ideal for a home mining system since it offers lots of capacity and 10 PCIe connectors on dedicated cables. If Thermaltake listens to our recommendations and fixes this unit, we will surely add it to our list. Cooler Master's MasterWatt doesn't fall short by much. Should the company rectify its shortcomings, it'll only have to tune its power-good signal accordingly. The Enermax Platimax D.F 1200W is only a hair away from the power-ok signal's requirement, however it only has six PCIe connectors which are too few for a PSU of such high capacity.
