The Best Gaming Power Supplies for 2015

Best Power Supplies 2015

It doesn’t matter how awesome your gaming computer is, if you pair it with a cheap power supply you’re asking for trouble. In this article I’m going to take a look at the best gaming power supplies available so that you don’t make the mistake of choosing a cheap low-quality power supply.

One component that often gets overlooked during the component-choosing process is the power supply.

However, without a power supply there is no way that your computer can even run.

And, your power supply is also important because the quality of the PSU you choose now will dictate what other components you can put into your computer right now and down the road.

If you choose a low-end power supply you won’t be able to put in a high-end video card.

Or, you technically could put a high-end video card in a system with a low-end power supply, but it probably won’t work and it’s possible that you could damage your system and destroy your other components.

So, even though your power supply won’t give you a higher framerate or increase your screen resolution to 1080p, it’s still one of the most important components in your system. Therefore, you need to take your time in order to make sure that you choose a high quality PSU for your new gaming computer.

In this post, we will take a look at the best gaming power supplies in 2015. I’ve broken down the categories into wattage mainly because there are a ton of different power supply “tier” lists out there and I feel like it would be easier for builders to search by the wattage they need. So, there are four different categories: the best power supplies over 1000W, the best power supplies between 800W-1000W, the best power supplies between 600W-800W, and the best power supplies between 400W-600W.

There are multiple options for each wattage range, but know that this list doesn’t include every quality power supply out there. Some have been omitted, not because they aren’t quality units, but rather in order to keep this list from getting out of control. I will continue to update this list on a regular basis.

There aren’t a whole lot of gamers out there who will ever have the need to use a power supply larger than 1000W. Really, the power supplies in this range are monsters and are best suited for enthusiasts looking to build extreme setups.

So, if you’re not looking to run 3-way or 4-way SLI/CrossFire and overclock your CPU and video card to record-breaking levels, there really isn’t need for such a large power supply. However, if you do need that kind of power, then these units will serve you well.

LEPA G Series 1600W 80PLUS Gold Full Modular PSU ($275-$320)
(Prices fluctuate–check here for current pricing)

Best Power Supply for Gaming 2013Do you want to run quad GTX 780 Tis in SLI configuration and laugh at the extra headroom you still have? Or, would you like to move off the grid and power your small log cabin using a wind turbine? Either way, this PSU could probably be used in both scenarios… With all joking aside, this power supply is likely the result of two Greek Gods having a baby together. Sure, it’s a little ridiculous for a power supply, but if you’ve got the money to do so, then you might as well get as ridiculous as possible.

LEPA G Series 1600W Specs

From 22-454 on Amazon:

Price was the best online, arrived on time, product had all the necessary cords and extensions. Great deal. Installation went well and smooth. No problems

From SaintsWord on Newegg:

A solid 1600 watts of juice and every bit of power & the average user will never use. Fair length vs other PSUs from the past like the Koolance 1700. You can bet your… cash… it’s future proof!


Thermaltake Toughpower Grand 1200W 80PLUS Gold PSU ($170-$200)
(Prices fluctuate–check here for current pricing)

Best Gaming Power Supply 2013While this power doesn’t crack the first tier of PSUs it still sits in the second tier. And, it gives you more power than you could ever need. With 1050W you have plenty of room to add multiple high-end video cards and overclock your processor to extreme levels without pushing this PSU too far. And, with an 80Plus Gold Certification you can bet this high-powered PSU will run efficiently for a long time.

Thermaltake Toughpower Grand 1050W Specs

Customer Reviews

From Writhe on Amazon:

Well made, reliable, plenty of juice to power a beasty machine. Highly recommend this power supply. The only complaint would be the cost but then again Thermaltake did not compromise on the build quality.

From Wes on Amazon:

The title says it all. What more do you want here. More than enough power, modular and runs quiet. The supply looks fairly stylish as well. My price point made sense so I jumped.



Even a power supply in the 800W-1000W range is going to be overkill for 90% of gamers. Again, unless you’re planning on running multiple video card configurations now or in the future and getting into some extreme system tuning, there really isn’t a need for this much power.

If, however, you want to run a 2-way SLI/CrossFire setup with two high-end video cards, then a solid 850W power supply will do the trick. And, these units will give you plenty of headroom to build a ridiculous setup.

A few months back I reviewed the SeaSonic M12II-850W Bronze power supply and found it to be an exceptional unit. With 70A on the +12V rail, a fully modular design, and a 5-year warranty, you can rest assured that this PSU will treat you well for a long time.

While 850W is  overkill for a single video card setup, this power supply is a great option for anyone looking to run 2-way SLI or CrossFire configurations. And, for how much power you get out of it, it is priced very well.

Customer Reviews

From R. Davis on Amazon:

Seasonic power supplies get great reviews throughout the internet and this unit is no exception. I have it powering a Gigabyte mainboard with an AMD FX8350, Corsair 240mm closed water cooler, 16gb Hyperx ram, 2x GTX 760 SLI, 1 SSD, 3 mechanical HDD’s, a blu ray burner, and a DVD burner. The system runs like a champ with no dropouts. I join a list of very satisfied Seasonic owners. I highly recommend this product!

From Tyler Atkins on Amazon:

This is a great power supply, and I love that it’s 90% modular. As another reviewer pointed out, the only cables that aren’t removable are the ones you will need for just about every PC build. There are lots of additional cables and there should be plenty to suit all your needs. This should provide plenty of power for anything but the craziest PC build, and so far I haven’t had any issues with my components not having enough power.



The 600W-800W range is the high-end for single video card setups and the low-end for 2-way SLI/CrossFire setups. A quality 700W-750W power supply will allow you to run two moderate video cards in SLI/CrossFire configuration. So, that makes PSUs in this range great for anyone who wants the option to upgrade in the future.

These power supplies will also give you quite a bit of headroom for system tuning if you’re building a high-end single video card setup. However, even if you do want to use a high-end video card like the GTX 780 Ti, a quality 550W power supply will give you enough power as well.

Best Gaming Power Supply 2013With the PC Power and Cooling Mk III 750W PSU, you will not only get extremely high quality from a tier 1 power supply, but you will also get a modular design and as close to a silent PSU as humanly possible. I’m not kidding, the Silencer MkIII IS silent. Even if you could careless about what kind of noise your power supply makes, the 80Plus Certified Silencer is still one of the best PSUs around. And, it has more than enough power to allow you to overclock and run dual video cards. What else could you possibly want?

Customer Reviews

From J. Miles on Amazon:

I have used PC Power and Cooling power supplies for over 20 years and have consistently been impressed with their stability, reliability and customer service. This power supply appears to follow the same standards of their previous models and has some noteworthy features that make it standout from the competition. The most significant is the semi-modular design which retains hard-wired connections for the important items—such as motherboard, CPU (dual connectors) and video. The modular jacks are unique in that they use a variant of the balanced jack connector for pro-audio use which includes a screw-down hold down nut. This setup provides a very secure connection for the modular cabling—unlike the majority of the competition that simply uses snap-on Molex type connectors for highly stressed and possibly high current connections. If you are looking for a premium power supply for your new computer – look no further than the PC Power and Cooling Silencer MK III…

From Allan Landwer on Amazon:

Extremely light for such a huge modular power supply. It has a very quiet fan and is very well made. Highly recommended.


Seasonic 80PLUS Power Supply M12II 620 BRONZE PSU($80-$100)
(Prices fluctuate–check here for current pricing)

Best Gaming Power Supply 2013There’s nothing like getting a modular  600+ watt 80Plus Bronze PSU made by a tier 1 power supply manufacturer for under $100. If you’re not planning on running dual video cards, overclocking, and running a bunch of other peripherals  then you really won’t find a better PSU than the M12II. This PSU is seriously everything any moderate to high-end gamer could hope for.

Seasonic M12II 620W Specs

  • Tier 1 PSU
  • 620W Max Power
  • 80Plus Bronze Certified for high efficiency
  • Ample +12V outputs
  • Active Power Factor Correction
  • Double Forward Converter Design
  • Uses highly reliable Japanese brand capacitors for durability and stability
  • Modular design helps with cable management
  • 12cm ball bearing cooling fan makes for excellent cooling
  • Compatible for SLI/CrossFireX setups
  • 5 Year Limited Warranty

Customer Reviews

From J. Cole on Amazon:

There are many things to like about this PSU. The warranty is good for five years! That really speaks to Seasonic’s confidence in their own quality control. The power supply is well put together and I really liked having the modular cables (there are plenty of different cables and they are all wrapped in nylon mesh). If you’re not sure what modular cables are: they allow you to plug in only the cables that you need for your system so you don’t have a bunch of extra, unused cables taking up room in your case. The PSU even comes with a bag to keep the extra cables you won’t use. It is worth pointing out however, that the 24 pin motherboard connector and two 8 pin CPU connectors are not modular and it’s likely you won’t be using the second 8 pin. This power supply is 80 plus bronze certified, which by itself means almost nothing (just like the energy star sticker), but I did a lot of research before purchasing this PSU and tests confirmed that it actually meets the claimed efficiency rating. You can often get this PSU for $80, which is outstanding when you consider that similar PSUs are often priced a lot higher. Finally, this power supply has an output of 48 amps on the 12V rail. This should be good enough for just about any single graphics card system and for a number of SLI systems too (obviously, check the specs on the box for your graphics card).

From Ganglion on Amazon:

My Seasonic PSU arrived a day earlier than I was expecting it to. Everything that was advertised as coming with the PSU arrived without problem. Installation was quick and painless. If you’re in the market for a PSU that doesn’t break the bank this is the way to go. With 620W I still have room to add another video card for SLI.



This range of power supplies is the most practical for the majority of gamers. If you’re building a budget system, a 450W power supply will more than do the trick. Even if you’re going with a a powerful video card like the GTX 780 Ti, a quality 550W unit like the ones listed in the chart below will get the job done.

So, the bottom line is that, unless you’re building an extreme setup that utilizes multiple video cards (or plan to in the future) the power supplies in this list are probably the route you want to go.

With dual +12V rails you can bet that your system will remain stable for a long time with this tier 2b PSU. While the wattage may seem a little low and it isn’t modular, don’t be fooled into thinking this PSU isn’t a good choice for you… this power supply can definitely handle some of the bigger named video cards (GTX 660, GTX 660ti, HD 7850, etc.) and will give you more for your money that you could have ever imagined.

Customer Reviews

From Fred Savage on Amazon:

I am running a AMD FX 4170, 7 fans, a Visiontek HD 7850 Graphics Card, 2 HD, 1 DVD Burner. This thing handles it all great and without any issues what so ever. I wanted to keep my power bill down and have a gaming rig, and this definitely performs. The wiring is easy to work with in my case (Cooler Master Haf 922) and I have every connection I need.

From Amy on Amazon:

I bought this power supply for my first computer build and I am very pleased! I have been using it for over two weeks now, non-stop, and it has not failed me once. It is actually very quiet (not silent, but quiet). I don’t notice any difference in noise when I start playing games such as Skyrim and Left 4 Dead 2. Most of the noise in my computer is coming from the case fan in my Cooler Master Elite 430. I will be upgrading my graphics card soon and I plan on updating my review saying if there are any differences when the power supply is under load. I am currently using about 300-350W.
