Just looked at my mobo guide online. A dip stick tech at frys told me to use a 450watt psu turns out I needed a 500 Or greater for optimal speed for what I got in it
AMD_Man, Zohan hijacked the previous thread; you were accidently responding to him instead of the original poster. I've split the post off and merged it with another hijack of his.Your specs on your first post list a 750 watt PSU. Anyways you need a minimum 600 watt PSU with 42 amps on the +12v rail for a GTX770.
