Im working wth a computer that lost its power supply. Specs are not needed, my question is very general. Helping troubleshoot via telephone. Bestbuy brand power supply died. Owner replaced it with a Thermaltake PSU. The system shuts off after heavy usage like gaming and stuff. Visual inspection shows that the 4 pin ATX connector socket on the mobo next to the CPU has some melted plastic inside it, so the new PSU connector doesnt fit snug. If the connector is held down with tape, it will stay on longer, but eventually shuts off again. I was wondering if I could clean the plastic off, or just get a 8" 4 pin extension cable, plug the female end into the new PSU, cut off the male end and solder it to the mobo. I know that I will have to be careful and make sure nothing will short out. Just wondering if that would be a solid fix or not? Thats the only visible damage. Thanks in advance!
