I have the two GTX 570's SLI under water at 1050mV's Core Voltage with 890MHz Core Clock and 2000MHz Memory Clock (still plenty of room for overclocking). I have 4x4GB memory, 16 fans, 1 pump, 4 SSD's, 4HDD's, a sound card, and an optical drive. My PSU is the Corsair AX1200, we're about the same efficiency (mine's a few % higher).

These are watts being read from the wall with a Kill-a-Watt meter:

219W's Idle

335W's CPU 100% load using Prime95 Blend test with an i7 2600k at 4.9GHz

601W's CPU not being stressed, GPU's being benchmarked by Unigine Heaven V2.1 default settings but with Anisotropy: 16; Anti-aliasing: 8x; and Full Screen at 1920 x 1200. 501W's with stock clocks and voltages on the GTX 570's.

687W's CPU 100% load using Prime95 Blend test and GPU's being benchmarked by Unigine Heaven V2.1 default settings but with Anisotropy: 16; Anti-aliasing: 8x; and Full Screen at 1920 x 1200. 595W's with stock clocks and voltages on the GTX 570's.

This is drawing from the wall with a PSU at about 90% efficiency. You have room.
