random reboot?

I just built a new system thats having random reboot issues only when I game.

Its completely stable with a slight over clock to 3.1ghz (E6700). I was able to run Prime 95 for 2+ hours stable and computed Super Pi 1m in 16 seconds.

However, when I game (Counterstrike Source), it has random reboot issues. Sometimes instantly. Sometimes after a few minutes. Sometimes even after half an hour. It doesnt matter if its a firefight or just looking at a blank wall. It locks up / reboot randomly, but surely.

I am running a single 7900GTX (Dell OEM brand) on a Asus P5N-E SLi board.

Could it be a PSU issue?

BFG's website says "A minimum 400W system power supply (with 12V current rating of 26A or more)" for their 7900GTX. "Minimum 500W system power supply (with 12V rating of 34A)" for their SLi config.

My PSU the Raidmax RX-630A. Its output is +3.3V@30A, +5V@45A, +12V1@18A, +12V2@16A, -12V@1.0A, +5VSB@2.5A.

Could that be the problem?

I should probably mention I have 6 hard drives hooked in also, 2 for main OS raid, 4 for storage. But during my testing, it didn't seem to matter much when I unplugged the extra harddrives.

Any help is appreciated. I have spent way too much on this comp to just 'live' with these random reboots.

Run Orthos for at least 8 hours because 2 hours ain't that long
 
My prior experiences with random reboots have been attributed to one of two things:

A) Not enough juice
B) Bad memory

It could be a hundred different things but I suggest starting with those two as the easy solutions. And don't pay attention to what nVidia says. It depends on how much power is being consumed by everything else you have hooked up to your system.
 
I'm in agreement with both replies to your original post.

Orthos or Prime your system for a minimum of 8 hours to ensure stability... I'm a little more nala when it comes to system stability, so I will Orthos my system for at least 24 hours before I deem my overclock stable. And my PC is not just running Orthos while it's being "Stressed", I also like to run other application while Orthos is running.

You may have diagnosed your own problem... think about it. When does the videocard demand the most power???
Since your reboot issues happens when you "game", you may want to take BFG's advice. Do you have another power supply (with higher rated 12v AMPs) you can test with or borrow from a buddy?
You may want to consider a "quality" (not just a name brand, as some name brands suck too) power supply. If it doesn't turn out to be the power supply, hey, at least you have a good one to build your future machines around.
Best place for PS reviews I've found so far.... is JonnyGURU.com

Good Luck
 
Hey, thanks for the helpful replies. I am not 100% sure but I would bet that the PSU is my problem.

I'll keep you updated on my progress or lack of.
