I sense a strong electrical presence inside my PC case.
I've started noticing a strange sensation of electricity running through my PC case. It's not a shock, more like a vibration. What worries me is that this hasn't happened before. I looked up possible explanations and found a few. One possibility is exposed wires, but I checked and none were visible. Another point mentioned is the lack of grounding for the power source—my PC uses an extension cord connected to a wall outlet, which I think is grounded. My specs are: i3-3220 with 6GB RAM, GTX 750Ti, 256GB SSD, 500GB HDD, CM MWE400W. I’m not sure if these details matter yet. Would it be safe to assume this isn’t the main issue? I’m not confident, but I want to be cautious.
In areas with unreliable electrical systems (like the US), your power supply might not be properly grounded. My previous home had three-prong outlets that weren’t linked to a grounding wire because it was outdated and lacked proper wiring, so they installed them just to meet basic requirements.
You're probably experiencing half of the mains voltage through the class X capacitor (and possibly class Y, which connects live and earth). This helps tie the 0v DC ground to the live mains, reducing back EMF and EMI problems. It indicates your PC chassis's earthing may not handle the 60-120v AC ripple effectively. I recommend verifying the earthing of the case and, if necessary, adding a dedicated wire to a ground rod.
