Thanks for the help guys

Still needing information if the PSU is enough. Anyone happen to know how much power 5830 + 5850/5830 eats at max load? (obviously undervolted) Huh

I draw exactly 1000w at the wall between 2 rigs with 9 cards at 0.95v while maximizing core speeds on a per card basis. There are 3 5870's, 5 5830's, and 1 5770. They PSU's are a 750W HALE90 (80plus gold) and a PC Power & Cooling TurboCool 1KW SR (80plus silver). Both are single rail.

I also have an Antec 550w double rail PSU. It -barely- can power 2 5830's without turning off; it requires both cards to be undervolted and virtually no CPU load or the PSU just turns off.
