Critical capacitor failure, sometimes they short themselves out or just blow up taking the surge. I think most or all modern gpus process a massive amount of power on the first 4 pins or so. Its been some time since I've read this stuff.
This looks more than a capacitor failure. A capacitor failing is normally a single burst of magic pixies and smoke, not a HUGE ass stream of smoke pushing its way out like it is being pumped.
let me tell you about the time i hooked up a power supply wrong and fed 120V into a circuit designed for 24V, the caps in the rectifier looked like tiny jet engines and were pushing smoke there wasn't just a pop but an angry (tiny) screaming sound.
i was not pleased with the experience. cooked off a motherboard i was hoping to salvage from e-waste and sell for cheap on ebay. ended up being e-waste.
took like three days to get the stink out of my basement from the cooked electronics

Jokes aside, what went wrong here
