Not sure where to post this best, it's kinda PSU related.
I just spent the last five hours troubleshooting my PC, finding out that one of my GPU power cables melted which seems to have caused a brown out whenever I started a 3D application.
This is a genuine Cablemod cable which was powering a GTX 1080Ti without overclock. All three 12V wires melted on the PSU side. The center one (2nd connector pin from the top) was the worst, the wire came right off. The top two connector pin housings melted too and the topmost one broke off and is partially stuck in the PSU connector. The PSU (Corsair AX 1200i) seems to be fine, it passed its self test.
My question now is, how likely is this to happen? Did I just get a bad cable? I participated in the LTT Folding (at home) month 2019 and the GPU ran at 100% for ~14 hours a day for 35-ish days, could this have been too much?
In the end I'm glad nothing caught fire.
