Issue with power cable and PSU connector.
Issue with power cable and PSU connector.
The power cable port had a minor issue last week (or two weeks ago). It wasn’t a major burn and the computer was working properly, though I detected a faint electrical odor. After replacing the port with a new cable, everything seemed normal for some time. Recently, I caught a weak burnt scent, which isn’t as intense as before. Given my sensitive sense of smell and regular smoke in my area, I’m uncertain. I usually run the PC for about two hours before shutting it down. I noticed a black mark on the cable, but when smelled directly it doesn’t have that strong burning taste. Could the plastic still be fresh? The socket appears intact, though. I’m still under warranty—can I request a return shipping label? Updated August 10, 2022 by davoi_encounter added further details
The cable is upgradable and follows a standard. The connector fitting into the power supply is IEC C13, so you can look it up on Amazon or local shops for a matching power cord or computer cable. The power supply’s plug appears to be in good condition. If needed, use sandpaper to smooth any oxidation on the pins—it increases resistance and can make the plug hot. I believe the PSU socket is fine and you likely don’t need to return it for replacement. The pins are solid-core and thick, so the other end should properly engage the contacts to ensure good connection. Occasionally, contact inside the plug may stretch, reducing pressure on the pin and causing sparks or higher resistance, which leads to heat and a burning odor from the plastic. A tighter connector with more secure holes would help. You can swap the receptacle, but it requires removing the socket, desoldering several wires, and opening the PSU. It’s doable if you have the right tools, or you could take it to a repair shop for a quick fix. If you purchase one, soldering is straightforward with proper equipment (or a local service center can handle it). Some options are available online: https://www.digikey.com/short/2df149bt. If you buy one and the work is simple, it’s worth trying unless the pin surface shows clear damage.
That's correct. If you can, get it fixed. Anything that caught fire from the inside might not be fully safe anymore. Most electrical items that burn should be swapped out and not operated until they're safe. Updated August 10, 2022 by Bombastinator
I've never encountered a soldered house receptacle. It might actually refer to a computer port instead.
The situation could involve melting metal. @mariushm outlined the concerns. From the photo it seems like a quiet PSU is the issue. I’m unsure if it’s available online or in a physical store, so I don’t know the exact process you’re dealing with. It looks like both the cord and the PSU need fixing or replacement. I’ll check the wall outlet too; it might be okay but could have been damaged. The main challenge is figuring out what actually caused the failure. Most likely cause is the cord.
