This came into my service area the other day. Card was able to run basic benchmarks but at random times, would black screen. Cable shown is the included 3 8pin to 12Vhpwr in box.

Second time seeing this in person , first time documenting it! I was also aware other users experienced the same tragic fate with their AMD 12vhpwr cards but who doesn't love some good tech gore?!
The receptacle on the card looks fairly good at first glance until you get a light right to the back and some black loveliness shows its face.
