Dunno the case starting sparking the pcie slot melted and took the 3080 with - it i was using a corsair rm1000. Just gutted as 3080 cost the earth. I paid just over 800 for mine. The joys of PCs right.
That means likely:
- Either card possibly failed drawing crazy amount of power from PCIe slot burning it.
Nvidias already exceed 75W limit of power drawn from slot, so wouldn't need much of VRM problem for that to go off the charts.
- Alternative is that motherboard's PCIe slot was somehow faulty with contacts eventually shorting.
And without current limited wire groups in very high power PSU, it wouldn't notice any shorts untill current exceeded 90A level.
Which is very hard to exceed, because resistance of PSU wiring and PCB traces from 24 pin connector to slot could keep current below that.
Card failing first should show as burnt components/damage on PCB around those etc signs.
Again if PCIe slot itself shorted, there shouldn't be damage in card outside slot contact.
What the hell happened. It’s not like you have old past it components. Not sure about your PSU though.
