During the warranty period, I'm still trying to figure out what's going on.
I've noticed similar discussions, and usually it's due to a low-quality PSU, insufficient power supply, or simply an old PC needing a new one. My machine is only about a year old, and I assumed the PSU was adequate.
The GPU temperatures stay around 80°C. I didn't overclock and even skipped activating XMP for my RAM. I haven't opened the PC much since installation; the only potential issue might be the HDD cable added to the PSU.
It could be a faulty cable or PSU altogether. If that's the case, wouldn't it have failed sooner?

It doesn't appear to have melted. It seems the cables were likely damaged when they were pulled too hard, causing the insulation to be stripped. The wires should be reinserted and properly crimped.

Yes, it is better not to tug on the wires, particularly when using 18g wires as Seasonic does. The PSU should be connected via two separate cables to the GPU or a single daisy-chained cable.
