I can feel electricity through my PC case

[EasonIDontKnowAnything]

I've recently noticed that I can feel electricity through my PC case. It's not like I'm getting zapped, instead it's more a vibration? The reason this is so concerning to me is that it wasn't something that happened before.

 

I did do a quick search about this issue and found a couple reasons why this might be happening. Exposed wires was one, but I checked and there weren't any. The PC not being plugged into a grounded wall outlet is also cited as a possible cause, but I'm not sure that's the culprit since my PC is plugged into an extension cord which is plugged into a wall outlet (that I'm pretty sure is grounded?).

 

Would like to get some advice. I'm not exactly stacked. I can afford a new PSU if that's the issue, but only barely, so hopefully that isn't the issue here? Do I even have to be worried at all?

If you live somewhere with sketchy power standards (including the US), it's entirely possible your outlet isn't grounded. My outlets at my old house were three-prong but the grounding pins weren't connected to anything; the house was old and didn't have grounding wires, so they just put useless three prong outlets on to get past inspection.

 What you're likely feeling is 1/2 mains voltage through from the class X (and possibly class Y, those go between live and earth) capacitor that ties the 0v DC ground to live mains to reduce back EMF and EMI and other issues. That suggests the earth on your PC chassis is not sufficient to bleed the roughly 60-120v AC ripple to ground. I'd suggest you double check the earthing/grounding of the case, and if needed run a dedicated wire to a earthing rod in the ground if it's that much of a concern.

Try plug in directly to the outlet or directly on a different outlet.
