what kind of PSU are we talking about, and whats the amp rating? how many 12v rails do you have, and what amps are they? I dont know the exact amp rating for that card, but you probably need at least an combined amp rating of 26-30 amps combined between your 12v rails. not having the proper amp rating could cause those issues, and its an easy thing to check (just look on the side of the PSU it should tell you how many 12v rails you have and how many amps with each) though I would tend to think this is a driver issue like previously stated. I would update your drivers, and after running a PSU calculator and making sure your PSU can handle everything, and your still having problems, Id contact customer support.
