Electricity leaks into case

I first detected this problem when my mic started acting up , creating weird buzz sounds . Went to the back of the case to check something and the mobo IO zapped me . From the intensity of the shock i think it's 12v ( can bear it for a sec or two , but i have no way of measuring it ) .

 

Took a screwdriver that had those handy led lights in it that light up if you touch electricity and i sure lit up if i touch things ( IO , CPU cooler fins , GPU cooler fins , GPU IO , PSU outside grill )  and NOT on some other things ( PSU case, mobo mounting plate )

 

The first thing i did was unplug it by removing the cable from the PSU , electricity was still there ( probably stuff inside PSU still holding charge ) , then i unplugged the 24 pin and cpu 4 pin and gpu 8 pin and 6 pin , and checked again and it's still there .

 

How should i proceed ?

 

Relevant specs :

 

Case : Corsair C70

PSU : Corsair CX600

MOBO: System specific H61 Asus matx that i pulled of old pc

1: you should be in a grounded outlet.

2: if you arent in a grounded outlet (shame on you) and have a reversible wall power plug design, swap it around. i have a bunch of devices with this exact same issue. (devices that claim to be "double insulation - no grounding required")

The motherboard has capacitors on it that also hold charges.

Is your cage plugged into a grounded outlet? If you're in the US, you need 3 prongs. 

^^^^^^ This happened to me when I was doing a gig. The ground pin of an extension cord was missing and the janitor plugged the cord in wrong. Since neutral connects to ground in most cases (no pu intended), this will lead the hot to actually be going through neutral, which is connected to ground, which goes into your case.

I've been using that outlet for years and i've never had that problem , it only has two prongs so it probably doesnt ground since nothing makes contact with those connectors on the edge

 

i'll try and change power chords , would it instantly disappear if it was the outlet ?

You need to get an electrician in and add a proper grounded outlet, changing power cords will not do anything, or run an appropriate sized extension cord to an outlet that is grounded. If your using the Type F plugs they do have grounding contacts build into the plug so it may have to do with the wiring in the walls. Your running the risk of the case building up a charge that can potentially be lethal if it that charge were to pass through someone's heart.

What i don't understand is why is it so strong now ? Until now i've felt it REALLY faintly once years ago...

 

It depends on the the components and how it builds up it's charge. It's quite dangerous to run appliances that are not double insulted without a ground since the case of the PC is metal and if something were to go wrong with the PSU or a component that shorted out to mains voltage you can get a full zap which would not be good.

 

I would highly recommend to not use that plug and find one that is grounded instead before going further.

And of course that's the main point to having a grounded appliance - it protects the users.

Found grounded plug ( one with the little metal pieces on opposite sides ) IO still zaps me :/

Hmmm if the wall outlet and cord have grounds you might have open grounds in the home especially if it's an older home, back in the day they didn't connect them or they didn't use ground wires. At that point unless you get something like an outlet tester it's hard to say if the plug is properly grounded.

It's probably worth getting a tester and testing them all since this problem suggests there could be danger with the current setup.

If you're sure that outlet is grounded then I suggest looking at your power supply.

I also don't think it's a bad idea to do a double check to ensure that it is properly grounded.
