WHY YOUR PSU MATTERS

NOT ALL PSUs ARE CREATED EQUAL

Your power supply is the driving force of your system. It powers all your components, defines your potential upgrades, and ideally does so efficiently while keeping noise to a minimum.

When choosing your PSU, first decide what you expect of it. How much power are you going to need at peak load? How important is power efficiency to you? Always keep in mind that some portion of your power is lost as heat, and pay attention to the efficiency rating.

See below for more details on these factors, and how the CORSAIR PSU lineup measures up with your priorities.

HOW TO CHOOSE A PSU

BUILD CONSIDERATIONS

Nobody likes surprises on build day. When you start opening boxes, you'll want to be sure that your PSU fits the size restrictions of your case.

In addition to sizing, consider if you want to invest in a PSU with modular cables (we certainly recommend it) and whether you're going for a custom color scheme to personalize the look of your system. With modular power supplies, you can purchase sets of different colored cables to help create that unique aesthetic.

Use the CORSAIR PC Builder to ensure a PSU that meets your needs.
