Hello,
is there a way to test it mine is still working? It makes a high pitched sound when plugged in, oh, and it gave me a sweet shock - aside from the fact that I'm an idiot - is my PC issue probably NOT the power supply?

well did it shock u just the metal cover, or did u open it and it shocked u by an internal comprontent? if it was just the cover, throw the thing away...
high pitched sounds usually mean a vibrating/resonating coil or bad capacitor. the 1st is not bad its just annoying, but if its a bad cap then replace the psu. if this psu is a standard power supply, then you can test it out by shorting the green wire in the big 20 or 24 pin connector to a nearby black power. this will get the thing to at least turn on (if it works)... if it fails this test, then yep its the powr supply.

I'll try that - thanks for the speedy reply and thanks for being so descriptive!
I took the cover off and (like the electrical un-genius I am) I rested my palm on one of the two silver alloy-aluminum-looking-identical mine-towers.

I hope you know what I mean...hahah
But YES - the "guts" gave me a JOLT!

Just so people know some PSU will not power up without a drive or something connected to it. I have a few PSU's laying around and most will not power up without a hard drive or something connected.
