8x7990 Power Requirements

Hello all,

I was poking around trying to figure out the actual power requirements for a 7990, and the best I can come up with is a single 7990 has a maximum load power requirement of between 350 and 400 watts (I believe it requires a minimum of 35A on the +12v rail..)

This puts an 8x7990 (actually 2 systems with 4 in each), at 2800-3200w for just the graphics cards. If I include efficiency calculations, I'm actually looking at 3080-3520w for just the cards.

Is this accurate, or am I missing something?
