Extremely weak tingling sensation, it doesn’t occur with shoes; it appears only when I remove my socks and make contact with that specific spot on the computer.
Alternating current doesn't require a ground—just a hot and neutral connection. Because most floors are made of wood, like tile or carpet, rather than metal. I'm not grounded without shoes. Even a concrete floor won't conduct you. ---- Wait... OP mentions feeling the sensation even when the case is empty. He's just sensing the texture.
there might be a DC component in AC power, which could explain the tingling sensation. this happens when a body with sufficient capacitance lets current pass. if so, it’s a big misunderstanding on my part, but the electric tingle isn’t just a texture—it’s more than that. i’ve noticed this with aluminum chassis and laptop sockets that aren’t properly grounded.
The surface feels unusual at first. The markings in the skin and the marks from the process create that effect. Upon closer inspection, the lines extend from side to side. A clearer image would help. Noticeably, the case has rubber feet and no exposed wires. This section made me chuckle because the guy completely dismantled his setup. Lol
It's an odd feeling, having the PC empty except for the motherboard and power supply, with no processor or other components. When I connect the power cable, I see the PSU either off or on, located at the top of the box. I notice some static in that area. If I disconnect the cable from the power source, nothing changes. I'm concerned something might be wrong or if the motherboard is drawing power from the box itself. I'm not sure if you understand well—I can make a video if you'd like.
Absolutely confirming my idea that his casing isn't grounded. It seems he can sense the potential difference between ground and neutral through his body, which matches the current causing it. This is uncertain since it’s outside my expertise in this area. (Hope someone with deeper knowledge can help.)
Two things occur when you ground current: sparks and heat or the breaker trips. However, the last post varies from the initial one. If the PSU is fixed to the case, the case gets hot. So connect the PSU and test it. Or better yet, let your cat attempt it first—just in case it’s live and you’re grounded, the cat might be the first to face the consequences.
