Best Power Supply Units for Gaming 2020

Corsair RM750x

The Corsair RM750x is hands down the best overall power supply on the market. It delivers 750W of power, which is more than enough for most mainstream graphics cards and processors, and it’ll be a perfect amount for high-end gaming rigs. Additionally, it has an 80 Plus Gold efficiency rating, which is one of the best efficiency ratings for power supplies.

The RMX 750X comes with an excellent efficiency rating of 80 plus gold. Additionally, Corsair claims that this power supply offers some of the best voltage regulation you can find in gaming power supplies. User reviews also support these claims. In addition, the cabling is completely modular in nature. This is rarely found in the other power supplies on this list. The result is a faster installation since you can first mount the unit and then attach the necessary cables.

Its 120mm fan does a great job of keeping the PSU cool during gaming sessions, and it does so quietly, so you don’t have to deal with a lot of noise. Finally, it’s fully modular, which means you can attach or detach cables as needed instead of having to deal with those that are permanently attached.

Ultimately, the Corsair RM750x is a fantastic PSU that combines high power with exceptional efficiency. It’s a bit pricey, but considering the high performance it’s still a steal. Unless you have an incredibly rugged dual GPU PC gaming rig, this power supply will be perfect for you.

If you’re looking to build a compactness-focused gaming rig, we recommend checking out the EVGA SuperNOVA 1200 GM. It has 1200W of power and an 80 Plus Gold efficiency rating, and it has a 93mm fan that cools quite efficiently, but not as well as the other fans on this list. The fan is also a bit noisy when in operation, but the power supply is fully modular. It is also very compact, which makes it perfect for fitting into smaller PC cases. It delivers the power of a midrange PSU in the size of a low budget, and at a pretty solid price as well.

As you would expect from a product in this price range, the cable system is fully modular in nature. It will lead to a clutter-free experience when connecting various components. Plus, the cables are braided so they don’t get tangled. EVGA also used high quality components inside. We say this because all capacitors and other vital parts are made by Japanese companies.

This makes it a reliable product that will last a long time. On this premise, EVGA has been confident enough to provide a 10 year warranty on the Supernova 1200. The fan size is 140mm and it is manufactured using a double ball bearing configuration. You’ll be happy to know that no user has reported any issues with its noise level or cooling speed. However, its huge size and weight is a downside. All of that put into perspective, we have to say that you won’t go wrong with purchasing this high capacity power supply. In f

The SSR-1000PD Ultra is one of the best power supplies you can buy today. It’s clear proof that skilled engineers can extract performance from analog circuits that years ago we only thought possible with digital platforms. The + 12V rail of this power supply has one of the toughest charging regulations we’ve ever measured, while its other rails perform well as well. The ripple suppression is excellent, its transient response is top notch, the hold time is very long, and you get all the protection features you could want (although the OCP point of the 5VSB rail allows for high ripple under loads. heavy).

Although Seasonic’s best-selling power supplies come from the Focus series, combining good performance with affordable prices, its Prime Ultra line gets all the prestige. The loud noise we saw on the original Prime PSUs is resolved (Platinum and Gold models benefit; the Titanium series was already much quieter). And the removal of capacitors from modular cables, while maintaining extremely low ripple, is also a major breakthrough, allowing modular cables to take up less space. Speaking of cables, we should mention this unit’s 180o SATA connectors and SATA 3.3 support, which could come in handy if you want to take advantage of the power off (PWDIS) feature that some hard drives offer.

With its excellent performance, quiet operation and high build quality, the SSR-1000PD Ultra impressed us
