450W CORSAIR CX450 80+ BRONZE

$75

Power supply prices are in constant flux, so this part of the build is nebulous at best. Really, we just recommend using whatever 140mm PSU you have to hand or can get cheaply online. We’re using Corsair’s CX450, as it’s a good little power brick that comfortably provides all the wattage this system will need; anything in excess of 500W would be overkill. The CX450’s low price means that it isn’t modular, which will leave us with some excess cabling to deal with, but that’s not the end of the world. If you do happen to have a modular power supply, go right ahead and use that instead for a slightly tidier build.
