Hi all,

I'm having a bit of trouble with a new build. I've been testing it's capabilities with Oblivion, and the system will power down, without warning, as if someone pulled the plug. It only seems to happen when playing Oblivion, but I have no other real intensive games.

I've noticed that if I have anti aliasing turned on, it happens nearly immediately when I go outside within the game.
Without AA, it runs the game fine for a few hours, but eventually powers offf.

At first I thought it may have been an overheating problem, but my CoreTemp readings all seem to be under 55C.
Then I thought it may be power, so I unplugged the cd drive, and took the side of the case off (which had 2 LED fans, system still runs under 55 without them.)

I've flashed the bios, and that didnt seem to do anything.

I never assumed that the video card would be able to kill the power, but I've been wrong before.

Would you say this is a power, mobo, or video issue?

No wonder... Rosewill PSU :p that cheap piece of junk is overloaded on the 12V rail most likely and shutting down. You skimmed on the PSU and now you're going to have bit the bullet and buy a decent one ;/ Im sorry this happened to you, but when this happens one learns the importance of the PSU (I did the exact same thing 9 months ago when I built my PC).

Any of these should get the job done:
