Reportedly, an updated 12V-2×6 power cable is implicated, as opposed to the older but closely related 12VHPWR cable, which is a worry.

For the record, the card in question was a Zotac RTX 5070 model paired with a Seasonic Focus GX-750 power supply. It's worth noting that it was the cable that suffered unambiguous damage here, not the graphics card or even, seemingly, the power connector or socket.

This says to me, a dumbfuck stone mason with limited electrics experience, it's possibly an issue with the cable. Though the issue with the cable may never have presented itself if it weren't for how Nvidia, apparently, routes all 12v lines into a single line on the board.
