I think my PSU is failing.

post #1 of 6
Thread Starter 
My computer started shutting off during my gaming sessions three times today. After the third time it won't come on anymore. The only thing that comes on is the PSU LED, the green motherboard light and the PSU fan (although it sounds and feels like its spinning slower). Nothing else turns on and I reseted all my connections and it still happens. Do you guys think I may have a failing PSU?
What's going on.

its possible if you have a spare laying around you can always fire that into your rig and test. also take your psu out of the case and conenct a fan to the molex connerctor and put a wire between the green and a black connector on your 24 pin plug on the psu and see if it turns on

Definitely doesn't sound good..luckily replacing PSUs isn't expensive even for quality units

Shorting the green wire isn't the best way of testing a PSU. I've had occasion where the PSU would still start like that, but it would fail to boot a system. You can't go wrong with a $10 PSU tester.

On topic, what were your temps like during the gaming sessions? It sounds like a PSU failure, but could be overheating too.

Cpu never went higher than 60c and gpu's got around 65c during games.
Sadly I don't have another psu to swap.

PSU testers like that are a waste of time. They don't really tell you enough to know if the psu is working like it should or not. I've seen more than enough of them say a Psu that wouldn't power up a system was good.
