Problem with Video Card? Overheat? Not enough power???

[Deptacon]

Ok, I running 2 BFG 6800GT's on SLI, and in game snow if I play for more than say 10-15 minutes, the video starts blacking out, in diamonds from the center of the screen. I think I may not have enough power since I added the 2nd card about a month or 2 ago. Does this sound accurate? or is actual hardware failure on the card(s)?

Tell me what you guys think....

what's your system specs and PS?

2 BFG 6800GT's SLI
ASUS A8NSLI Deluxe
1 gig 3200
AMD 3500+ 2.2

Power Supply 420W (I think)

Yepp, I would go with the psu being the issue. 6800 cards take up some serious wattage. Are you running more then one hd? how many case fans? cd drives? all this should be taken into account here as well. But I would bet on the psu being the issue, what make is it?

Sounds like it's probably heat to me, if it only happens over time.

Im running a thermaltake case, with multiple cans, im assuming its power as well. ITs the 420 that came with my thermaltake case, anyone got any good reccommendations for a PSW With more power????

500W Liberty Enermax or if you want a bit more headroom...OCZ 520W Powerstream

that power supply is definitely the problem. Most PSU that comes with case are generally mediocre in quality, except for Antec since they provide their own PSU

a quality psu with at least 450watts and 30 amps would do
