yes I have actually.
I have a 1000w Max output PSU, and I have had it stable draw from the wall at 1000w(its 80% gold certified, BFGtech GamerXtreme, 4 +12vRails, so this means about 800w output to the system).
With no video cards, it drew 400 for the CPU, RAM, Board, and 5 fans, and 2 HDDs, this was however under no load, as I had nothing installed except the OS to get board drivers in place before putting in the video cards.
Figure, if you use the PCIex16 slot in full, that is 175w for the board right there, and about 10w Per HDD, and around 10 per fan.
Plugged it in after I got it all installed, and for my rig It drew 1200 from the wall with 2 GTX460s, an slightly overclocked AMD PhenomII 955BE, and 8GB of ram, and with all my fans at full RPM, and 2 HDDs, while running a 2 hour long furmark burn test. Hopefully I dont need to get a bigger PSU when I get 2 580s, but I may have to if the 460s pull that much.
