I recently made some upgrades to my system (added a radeon HD6850 for crossfire, a few fans, and an i5 2500k cpu) and everything was going smoothly for a few minutes after boot-up until i got a blue screen. The pc then turned off, then on, then off and on again until i shut it off. I thought my PSU (the kentek 775W) might not be able to handle what i was throwing at it so i took one HD6850 out and booted up. i got a message saying i recovered from a problem and it said this:

Thats all i really know at the moment. So far it has run fine with one GPU out, but i cant tell if it was a software issue or if my power supply couldnt handle it.
My specs are:
24A each on the two 12V rails (equaling around 45A combined), for a max output of 540W on the 12V rails (and I would definitely say that that's a max rating and certainly not continuous). Pitiful for a supposedly 775W PSU.
Still, I wouldn't Crossfire with that PSU, even if it was capable. From what I can tell about it, it's liable to make a nice little light show for you at any moment.
