Computer Shutting Down Randomly

post #1 of 6
Thread Starter 
I have a 700 watt PSU, 12gb of ram, 3 monitors, and just put in a Titan. So far whenever I load up a GPU intensive game my computer shuts down. I opened up GPU-Z and watched the TDP consumption while loading up BF4. As soon as it got to 80% TDP the computer shut down.

Shouldn't 700w be enough? Could the PSU be bad?

ya know i had a 850w in my system running for years. last week when loading up games or benchmarks, my PC would re boot. I sent a RMA request to EVGA as i thought it was my GPU. They directed me to test PSU and or GPU in another system. My findings were that my PSU was the problem. Went and bought a new PSU and games and benchmarks seem to be fine.

I did some extensive testing thought the other rig was nothing close to my current one it did fail with just PSU and not my GPU.

Do you have a way to make trouble your other components in a system to rule out all options??

this is what they sent to me

check the power supply rails in the BIOS to see if there are any obvious fluctuations or problems. In the BIOS, Look for a menu called something like Hardware Monitor, PC Health, HW Monitor, etc. The 12v rail should be stable and be between 11.5v and 12.5v, the 3.3v rail between 3.135v and 3.465v, and the 5v between 4.75v and 5.25v, and they shouldn't fluctuate much if at all. If any rail fluctuates more than every 10 or 15 seconds, or it's outside these ratings, that rail may be failing and causing your issue. The BIOS reading is just a baseline reading at an idle state though, so it could be a false positive, meaning that the fluctuations don’t happen very often or only under high load. This isn't a definitive test the way testing another power supply is, but it can at least give us a good idea of how the power supply is doing.

I don't think so. According to this YouTube corporate video (skip to about 4:00), it looks more like a well-made but old design 400-450W.

Try removing the side of the computer case and have a table fan blow into it. If that at least reduces the shut downs, you probably have a weak power supply because power capacity drops with higher temperatures, roughly 20% from about 25 Celcius to 40 Celcius.

I'm guessing that the Corsair CX500 that NewEgg currently features for $22 after rebate and coupon code WEEKEBF11: link
