PSU:How to choose a Power Supply
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.
Corsair's website features a wealth of information about power supplies, including an online tool to help you plan your build. Explore the new PSU information hub and PSU finder tool at Corsair PSU Family, and visit their Explorer page here for more details.
