I was playing WoW and then my computer just shut off. I'm pretty sure the computer didn't overheat, i checked the temps while running WoW, the CPU is at 33 degrees Celsius and the GPU is 47 degrees. Is it my power supply?

It just shut off again, im sure it wasnt overheating, the temps weren't that high. When it shut off it wouldn't start up until i unplugged the power cable from the PSU and plugged it back in.
