PSU make and model and do you have the standoffs in place for the board?

what psu are you using? And the shock from the case is static electricity... There's some earthing problem...
Dont cheap out on your psu, buy a good branded PSU...

it's an AMD psu, i'm not sure which one exactly but its made by amd and is 450 watts

If you can't identify the make and model , it's most likely a poor quality PSU.

I don't think AMD even makes power supplies?

Do you often experience static shocks at home? My last apartment was terrible for static, I would get shocks touching anything metal, PC included. To protect my computer I'd always touch something grounded (e.g. a screw on my light switch fixture) before touching my PC. I've since moved (and humidity is higher because it's summer), and I no longer have a problem with shocks when I touch my PC.

What makes you think your USB voltage is high?

Does the pc run ok? If its does I would suspect you have a grounding problem with that wall socket or your mains wiring, do you get the same problem if you plug the pc in another socket?

I would hope a PSU that was shorting out to ground would not even switch on but maybe if its a low quality minimum safety feature unit it might.

Can you take the pc to a friends house and see if you still get the same problem? If you do then its most likely a faulty PSU which should be changed immediately, if you don't the you most likely have a grounding issue with your home wiring and you should call an electrician ASAP.
