Power Supply failing?

[ChezDispenser]

Okay, so I've had a recent spat of shutdowns when trying to play particular games. Originally, it was just stuff that was on the Frostbite engine; now it's gotten to the point where I can't so much as start FO4 without an instant shutdown. No BSOD; just an instant power-off. I think it's my PSU, and I wanted to see if there was anything I could do to repair the thing, or if I should just plan on buying a new one.
