I don't really need a 1250 PSU for a K64, right? I was thinking a 250 would work fine, as the boards are the only thing I need to power with my planned setup.
Im starting with a 550 watt dual rail 38 amps for, 2 k16, 2 k64's = 320 watts pulled....so.... even if over clocked down the rd,,,still plenty of room....ya even an old 250 will be enough for a singe k64. Some in here are going out and buying godly PSU's for a few boards.... i know a quality one is best though, so it doesn't blow and take out your boards with it...always that chance with any however....
