Best power supply for a gaming PC in 2022

The problem with choosing the best power supply for a gaming PC is that the PSU requirements for each system are different. Not only is wattage an important factor, but the size of rigs can vary widely, which means that there is not really a “one size fits all” solution. That said, we are sure you will find something that suits you in our shortlist.

You may not necessarily consider your power supply to be the most critical part of your PC, but if the best gaming CPU effectively functions as the brain of a system, a PSU is the heart of your rig. Think about it, the device provides the lifeblood that is electricity to your hardware, while the range of cables can even look like a root of arteries and veins at a glance.

If you invest in a quality power supply, it will probably be the longest member of your rig through many years of upgrades. But as expensive as some PSUs can be, there are many out there for builders who want to push the budget a little further as well.

EVGA Supernova 850 T2

The best power supply is the EVGA Supernova 850 T2.

What makes the EVGA Supernova 850 T2 a cut above most PSUs is its 80 Plus Titanium certification, which means it is 94% efficient or higher under a typical load. This means that the power supply wastes very little energy, which results in less excess heat and cooler operating temperatures.

It is fully modular, so you only need to route the cables needed to power the system. It is also built with Japanese Nippon Chemi-Con capacitors, which makes this PSU an always reliable part of any rig, plus it comes with a 10-year warranty period should you need it. While 850W should be enough for most people, you can also find 1000W and 1600W versions of this power supply.

  • 80 Plus Titanium certification
  • 10 year warranty period

Best 1000W power supply: Gigabyte UD1000GM PG5

Gigabyte UD1000GM PG5

The best 1000W power supply is the Gigabyte UD1000GM PG5.

If you’re thinking of buying one of the best graphics cards from the range of Nvidia RTX 4000 or AMD RDNA 3 GPUs when they finally launch later this year, you may need the 1000W monster which is the Gigabyte UD1000GM PG5. It is already prepared, with support for the new PCIe Gen 5 16-pin power connector, which will probably eventually power every GPU that comes our way in the future.

Of course, it comes with many other features you can expect from a top-level power supply, such as 80 Plus Gold certification, a fully modular design and a 10-year warranty. Gigabyte also claims that the power supply’s 120 mm smart hydraulic bearing fan should last 1.4x longer than a standard sleeve bearing found on some cheaper models.

What we like:

  • Built-in support for PCIe Gen 5 16-pin power connector
  • 80 Plus Gold certification

Best SFX Power Supply: Corsair SF750Check prices

Corsair SF750

The best SFX power supply is the Corsair SF750.

If you’re building a system in a compact PC cover, the small but powerful Corsair SF750 should be at the top of your list of potential power supplies to fill up your miniature rig. That said, it will also work great in a larger ATX chassis, thanks to the included SFX-to-ATX bracket.

The Corsair SF750’s Zero RPM Fan Mode ‘ensures that the PSU does not switch on the fan before it has to, keeps things quiet when you surf the web and starts things up when you play. It is also fully modular, and the cables with individual sleeves make it easy to direct them in the game PC. If your computer does not require 750W, consider the less powerful but less expensive SF600 or SF400.

What we like:

  • Zero RPM fan mode keeps things quiet until the PSU reaches 40% load
  • Including SFX-to-ATX bracket

Best offered power supply: Corsair VS500Check prices

Corsair VS500

The best cheap power supply is the Corsair VS500.

The Corsair VS500 costs just under $ 50 USD and is undoubtedly one of the most valuable PSUs available on the market for budget-conscious builders. Despite its cheap price, this power supply does not save on the 80 Plus certification, which means that it is by no means a waste.

The Corsair VS500 should have no problem fitting into almost any ATX PC case, thanks to the 125 mm long shell that makes it smaller than standard PSUs. A three-year warranty should help with any concerns about the reliability of this power supply, and you can even buy a 600W model instead if you need a little extra juice for your system.

What we like:

  • 500W for less than $ 50 USD
  • Smaller size makes installation easier

What power supply do I need?

To find out what effect on the power supply you need to run your gaming PC, you must first understand the requirements of the components inside the system. Usually the most important things to consider are the graphics card and the processor, as they are often the most power consuming parts of your rig.

Fortunately, tools like Seasonic’s power supply calculator make what would otherwise be a task of tedious and potential miscalculations much easier. Just enter the parts that make up your current or potential design and you will be presented with an exact answer as to what kind of PSU you need.

What is a modular power supply?

A modular power supply is characterized by the flexibility it gives you by sacrificing a fixed arrangement of power cables and instead allows you to customize the types of cables it uses to suit your particular design. This makes it easier to handle cables in your case, which means it is much less difficult to create the often desired clean look.
