My build is composed of the following, how many watts should I look for in a PSU?
Case - Cooler Master HAF 912
CPU - Intel Core i5-2500k
MB - ASRock Z77 Pro4
GPU - EVGA GeForce GTX 480
RAM - Patriot 2x4GB DDR3 1600
HDD - Seagate Barracuda 500GB 7200rpm
Optical Drive - LITE-ON DVD Burner
The amps on the 12v rail(s) is more important than the watts. Look at that first. And yes, the PSU's listed so far are all good.
