Failing PSU?

Well this has happend twice now in the last 2 days, I'll be playing a game (TF2 the first time and L4D2 the second) and all of the sudden my computer will just shut off as if it got unplugged. The first time I didn't think anything of it because the power cord was almost unplugged from the surge protector but then It happended a couple minutes ago and the cord is firmly plugged in. Could it be too much load on my power supply?

Its only 300w but I figured it should be more than enough for my 4650. I've got an extra PSU lying around I could try out.

What are your thoughts?

Have you checked if the fan on the PSU is spinning? This happened to me not too long ago, so I guess it's a suggestion that comes to mind.

A failing PSU can be extremely difficult to identify. Since you have a spare PSU, though, you have a convenient way to test assuming it is rated for a higher load.

Is that GPU idle temp? Temps seem a bit high. You could try OCCT. It shows graphs of CPU usage in relation to voltages. Might be useful for you. I think it has a PSU test but I haven't tried it

Bump. Any other thoughts guys?

Bad memory can be causing similar issues so, before you swap the PSU, run MemTest+ and make sure you don't have a bad stick of RAM. If your memory is fine, odds are you need a new PSU.

Good luck,
