I've been getting some errors occasionally with my GPU, and in the process of figuring it out, I've narrowed it down to the GPU itself, or the PSU. I haven't really paid much attention to power supplies over the years so I don't know if this is normal behavior or not.

During Idle the 12v averages about 11.85v, and when I put everything at full load (cpu, gpu, hdd) it decreases to 11.42v. It's not much of a drop, but I'm thinking it could be the problem. Any thoughts?

What specific errors are you getting that led you to suspect PSU or GPU issues?

As the PSU heats up. its transfer becomes less efficient. Obviously you want it as close to 12v as possible. The issue is less of a problem with the higher end multi rail PSU's such as the ones Enermax makes, and can be particularily a problem on the cheap generic ones. Blow any dust in the PSU out as best you can, if that doesn't do the trick, consider upgrading to something a bit higher end.

All kinds of weird artifacting and glitches. Here's a "screenshot" I sent to EVGA regarding the issue. Happens on very rare occasions, to me it seemed more like a video memory problem, had some issues during hardware video acceleration once. But power is seeming more likely.

Hah! Reminds me of crap my old Atari 2600 used to pull.

One way to check for VRAM issues is to look in your Windows Event Log for errors 500 and 501. The VRAM in my GeForce 9600 is beginning to fritz out, and those are the errors I've gotten left and right. "Windows Desktop Experience has degraded."

thats definitly hardware. Its either the card or the PSU. Either way I wouldn't even power the computer on until you get a replacement PSU because if it is a bad PSU, it may cook your motherboard.

Don't have one of those.

Well everything is under warranty right now, and has been stable for months, save for the few GPU errors. Can't live without my computer on. Guess I'll start looking for a good deal on a PSU.

And if the new PSU doesn't fix it, time to RMA that card. Smiley: nod

Was looking at this one, anyone suggest something different? I'm fairly broke pretty much of the time.

PSUs are one area where you really shouldn't skimp. This would be my recommendation.

Is that supposed to mean the PSU will explode my computer? :(

Raidmax has a reputation for building bad power supplies. I would look really hard at any power supply claiming 85% efficiency and isn't even certified 80+.


Edit note
replaced had with has
