Best power supply unit for PC gaming

It comes down to numbers when looking for the best power supply unit for PC gaming. As one of the most important parts of your whole set-up, you should make sure you have the right power supply unit (PSU) to ensure your PC runs as smoothly as possible. There are a few things you’ll need to think about when looking around for the best power supply—it’s not just a matter of finding the biggest one you can afford and hoping it will do the job.

When looking at PSUs, pay attention to the wattage, as you will need enough to power all the components in your system. Having a larger PSU than necessary won’t negatively impact any of your components, but generating more power than is needed could increase your electricity bill and generate more heat—problems that can be eliminated with a little research.

If you’re wondering how much wattage you need, the easiest way to work it out is to locate your GPU, motherboard, and PSU power requirements and add them together. If you round up the final figure by a small margin, you should be fine. As a rough guide, 500W is typically enough in most cases but it’s always worth checking before you make your decision.

But there’s more to a PSU than wattage. If you’re hoping to upgrade your build with an extra GPU or other peripheral connections in the future, a semi-modular PSU is something you might want to consider. This type of PSU will enable you to add extra cables as the need arises while allowing you to remove cables that you won’t be using—great for freeing up valuable space.

On a final note, compatibility is totally a thing when it comes to PSUs, so unless you want to put your entire rig at risk, don’t mix and match cables with different power supplies. To make things even more complicated, not all PSU cables, even if they come from the same manufacturer, are going to be universally compatible. To avoid any unnecessary frustration, take a look at your PSUs PIN connectors and make sure your cable set has ones that match.
