From what I have seen of the 4x4 platform, we're talking about a system that pushes 500w @ idle, and over 700 under load, correct? Yeah, I don't expect that I will be able to run more than my board, CPUs and RAM on my Toughpower 750w quad rail. The GPUs will be fine on the TT PurePower 250w GPU PSU (and I can grab another for 1 unit per video card, if need be). I figure the 4x4, loaded to the teeth with ram, and drives, and fans, will probably run me around 650w @idle, about 750-800w under load (GFX cards not included in that, since they are being supported by separate power supplies).
If the power requirements are really as the [H] predicted, I plan on going with this PSU:

And I already own one of these, but could add another:

You guys think that should fit the bill? And FTR, I know brand loyalty gets us no where...tell it to the people that jumped all over P4's that required RIMMs because they loved their OCd P3's so much.
Or you can just get one good killowatt psu for the price after all your little power supplies.
