faint hissing from power supply
I've got your joe-average ATX case and I can hear a faint hissing coming
from the power supply even after the computer is shut down. I can kill the sound by flipping the switch on the back of the power supply (which kills power into the psu). I know "faint hissing" isn't super descriptive, but can anybody tell me whether I should be afraid of this psu? Is in the process of frying itself? its capacitor? or some other part that I'd rather not fry? Or is it no big deal and some psus make a bit of noise? I don't have any past experience with this hardware, so I'm afraid I can't say if it used to be quieter or not.
