The problem with crowning the best power supply for a gaming PC is that each system’s power requirements are different. Not only is wattage an important consideration, but rig sizes can vary widely, meaning there really is no “one size fits all” solution. That said, we’re confident you’ll find something to suit you in our shortlist.
You might not necessarily think of your power supply as the most critical part of your PC, but if the best gaming CPU effectively acts as the brains of a system, then a PSU is the heart of your rig. form. Think about it, the unit supplies the lifeblood of electricity to your hardware, while its network of cables can even look like a jumble of arteries and veins at a glance.
If you invest in a quality power supply, it will likely become the oldest member of your rig over years of upgrades. However, as pricey as some PSUs can be, there are plenty out there for builders looking to push their budget a little further as well.
here is best power supply for a gaming pc in 2022
EVGA Supernova 850 T2
the better diet is the EVGA Supernova 850 T2.
What makes the EVGA Supernova 850 T2 a cut above most power supplies is its 80 Plus Titanium certification, which means it’s 94% or more efficient under typical load . This means that the power supply wastes very little energy, resulting in less excess heat and cooler operating temperatures.
It’s fully modular, so you only need to route the necessary cables to power your system. It’s also built with Japanese Nippon Chemi-Con capacitors, making this PSU an always-reliable part of any rig, and 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.
What we like:
80 Plus Titanium Certification
10 year warranty period
|EVGA Supernova 850 T2 Specifications|
|Watts (W)||850 / 1000 / 1600|
|Connectors||ATX 20+4 pin (x1) / CPU 4+4 pin (x2) / PCIe 6+2 pin (x4) / PCIe 6 pin (x2) / SATA (x10) / Peripheral 4 pin (x4)|
|80 Plus Certified||Titanium|
Gigabyte UD1000GM PG5
the best 1000W power supply is the Gigabyte UD1000GM PG5.
If you’re planning on picking up one of the best graphics cards in the Nvidia RTX 4000 or AMD RDNA 3 line of GPUs when they finally launch later this year, you might want the 1000W monster that is the Gigabyte UD1000GM PG5. It’s already ready, with support for the new 16-pin PCIe Gen 5 power connector, which will likely eventually power any GPUs that come our way in the future.
Of course, it comes with many of the other features you’d expect from a top-tier 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 smart 120mm hydraulic bearing fan should last 1.4 times longer than a standard sleeve bearing found on some cheaper models.
What we like:
Native support for 16-pin PCIe Gen 5 power connector
80 Plus Gold certification
|Gigabyte UD1000GM PG5|
|Connectors||ATX 20+4 pin (x1) / CPU 4+4 pin (x2) / PCIe 16 pin (x1) / PCIe 6+2 pin (x4) / SATA (x8) / Peripheral 4 pin (x3)|
|80 Plus Certified||Gold|
the best SFX power supply is the Corsair SF750.
If you’re building a system in a compact PC case, the small but mighty Corsair SF750 should be high on your list of potential power supplies to power your miniature rig. That said, it will also work great in a larger ATX chassis, thanks to the included SFX-to-ATX support.
The Corsair SF750’s “Zero RPM Fan Mode” ensures the PSU doesn’t kick in its fan until it has to, keeping things quiet when you’re browsing the web and kicking things up when You play. It’s also fully modular, and its individually wrapped cables make it easy to route them through your gaming PC. If your computer doesn’t require 750W, consider the less powerful but cheaper SF600 or SF400.
What we like:
Zero RPM fan mode keeps things quiet until the PSU reaches 40% charge
SFX to ATX support included
|Watts (W)||400 / 600 / 750|
|Form factor||Special effects|
|Connectors||ATX 20+4 pin (x1) / CPU 4+4 pin (x2) / PCIe 6+2 pin (x4) / SATA (x8) / Peripheral 4 pin (x3)|
|80 Plus Certified||Platinum|
the best cheap power supply is the Corsair VS500.
Costing just under $50, the Corsair VS500 is arguably one of the best power supplies available on the market for budget-conscious builders. Despite its cheap price, this power supply doesn’t skimp on the 80 Plus certification, meaning it’s by no means wasteful.
The Corsair VS500 should have no trouble fitting into almost any ATX PC case, thanks to its 125mm long shell that makes it smaller than standard PSUs. A three-year warranty should take away any concerns about this power supply’s reliability, and you can even buy a 600W model instead if you need a little more juice for your system.
What we like:
500W for under $50
Small size makes installation easy
|Watts (W)||500 / 600|
|Connectors||ATX 20+4 pin (x1) / CPU 4+4 pin (x1) / PCIe 6+2 pin (x2) / SATA (x6) / Peripheral 4 pin (x4)|

What food do I need?
In order to determine how much power you need to run your gaming PC, you must first understand the requirements of your system components. Generally, the most important things to consider are your graphics card and processor, as these are often the most power-hungry parts of your rig.
Fortunately, tools like Seasonic’s Power Supply Calculator make what would otherwise be a tedious task and potential miscalculations much easier. Simply enter the parts that make up your current or future build, and you’ll receive a specific answer as to what type of power supply you need.
What is a modular power supply?
A modular power supply is characterized by the flexibility it gives you by forgoing a fixed layout of power cables and instead allowing you to customize the types of cables it uses to suit your particular build. This makes it easier to manage cables in your case, which means it’s much less of a hassle to create the clean look often desired.
