Uh .. is there a Silent Pro M 600W or Silent Pro M 700W? Those two would be better.
Unfortunately not. In order to get some discount, I only have like 14 to pick from where most of them are 750 or 500 w. Would a Silver Power SP-S650, a Silver Power SP, or a XFX ProSeries Core Edition 550W be better? (I'm using i5 3570k)
