Can PSU cause graphic corruption ?

I just got a 9800GTX+ 3 days ago, and I have 2 crashing issues, the entire screen becomes corrupted, filled with lines and pink boxes and the computer hangs

1st - when I open a video file. Corrupted and hangs for 1 second and restart

2nd - when I start to run furmark. Corrupted and hangs

However, the card runs perfectly fine during gaming, Crysis and UT3, performs as it should, no corruption or crash.


Don't know if this is helpful but intel monitoring tool shows the 12v to be ~12.300 at idle, and when at full load such as furmark, it drops to below ~12.030

I'm just wondering if its possible for PSU insufficient power to cause those graphic corruption or it has to be the graphic card?

thanks for any input

Your PSU is at the bare minimum for PSU requirements on that card (450watt/24amp), and I'm not sure what they do for calculations but you might want to look at an upgrade there. While typically a PSU doesn't cause artifacting, it's possible. If you get a new PSU, then see if the card keeps artifacting. If so, then the card has some issues.

Sometimes cards only show their weaknesses in certain games/apps. I had a card that would work perfectly fine, except that some of the doors in Oblivion didn't render correctly and in the Deep Freeze benchmark, it would flicker a little bit. It was a video card problem. I sold the card to my friend and he has the same issues.

If you are getting video artifacts your card is either faulty, overheating or not getting enough power. have you installed lates Nvidia driver? Did you uninstall previous driver?

I have a similar problem, only it happens when it wants, more often during games. Same card, my build is in this thread...
