    Default One pin of the PSU male 3 pin has melted, but psu still works

    Yesterday during a load shedding, my pc was running while I was sleeping so the UPS failed & the pc turned off. Then after waking up, I saw that one of the 3 pin port of my psu that connects to the AC out via a 3 pin cable has burnt out & it's covering has melted leaving only a thin plate of metal sticking out from there. The PSU is still working, but I am confused about running the pc in that state. I am attaching a picture of what has happened here. Any suggestions on what to do is appreciated. Thanks.

    You should look for a replacement. Better not take chances. If you are interested I have a dead Delux PSU. You can have the 3 Pin port if you want.

    this is quite a rare phenomena! neway if the internal side of this connection looks ok then simply swap this 3 pin connection with a fresh one from a another psu. in addition do consider changing the power cable. I think your power cables female end is too loose.

    From any dead PSU, rating should not matter at measly wattages like 650W.

    Hell, it's probably fine to keep it running as is, even. That port is probably better built than anything you'll find here.
