Computer turning off while gaming

So a month or two ago this was the same issue and stopped for a while but has been happening again the last few days.

I'll be playing a game and then my computer turns off (sometimes 10 minutes in, sometimes 20-30minutes. And won't start up again unless I unplug the cable and plug it back in or mess with it a little bit. I have monitored CPU (Core Temp) and GPU (Catalyst Control Center) temperatures. Both were about 53C the last time it happened a little bit ago. So it doesn't seem to be an overheating problem, which makes me think it has to be the PSU.

I used compressed air to clean out everything and the CPU heatsink. And tried to just blow through the back of the PSU but nothing really came out that I saw. Should I just bite the bullet and try a new PSU? Or would the problem be somewhere else?


Specs --

Mobo: ASRock 870 Extreme3
CPU: Phenom II X4 Black 955
GPU: Radeon HD 6950
PSU: Cooler Master 750w
Mem: 4gb

Hmmm, the GX-450 is one of the few (if not the only) low-end unit from CM that HardwareSecrets passed, but you probably are stressing it, and their tests don't include longevity.
Replacing your PSU is not a bad idea. Another possibility is the VRMs are overheating, but having to unplug suggests a PSU problem is more likely.

Yep, I would put money that the PSU is failing. It's only a 450W model for a 6950 which should be a minimum of 500W. Here is a little bit of reading that is disconcerting regarding that model from Hardware Secrets review.

Linked the wrong one, it's just where it took me but it's actually a Cooler Master GX - 750W.

That's what I figured about unplugging. Won't turn back on unless I unplug and fiddle with it, other outlet etc. And I have tried other cables. It seems like CM mostly does 5 year warranties which I am still in for -- no issues since 2011.

Ooh, the GX-750 is likely using the same project that HardOCP called a "polished turd in a box" when they reviewed the GX-650.

Mmh, guess I'm in the market for a new PSU. Any recommendations about wattage and brands?

I have been running a nearly identical spec PC with a corsair TX series 750W for years and its been fine you will be fine with a good 600W I had the 750W as I used to run 2 x Radeon 4870s (which managed to kill an OCZ 850W PSU).

Corsair TX is good, Corsair CX is not. Anything built by Seasonic will be good, like their own, XFX, and some Antec. Delta-built Antec are also good. Superflower-built Rosewill Capstone are good too. For your system, 500W-550W should be sufficient.
