Unofficial 12V-2x6V Power Connector Melts NVIDIA GeForce RTX 5090

Der8auer got the card & cable & PSU.
Observed and compared the results with his own 5090.
Finds out there are 2 wires carrying 20A in stress testing. (Other wires carried ~5A)
It makes those 2 wires extremely hot and dangerous.

This does seem like the interesting part in this case. While burning 4090 GPUs seem to have been common enough I do not remember that many pictures of the same thing burning on PSU side.

This is the PSU used:

It only says PCI-E 16-pin but also ATX 3.1 that would imply 12V-2x6.

Also, as the PSU already implied, this is an SFF build.

I mean, a 5090 into this space? I would be quite worried about the heat by itself.

ASUS's product page is mislabeled. It is not ATX 3.1. It is 3.0, because for the PSU to be 3.1 it must have the revised 12V-2x6 socket.

Fortunately something like that already exists, but it’s unfortunate that nVidia couldn’t use it on the FE because… cost?

This is from some AIB variant:

Per pin current monitoring!

When you have this available it’s not difficult to write an instruction to shut down the load after it detects a discrepancy (beyond a threshold) in current between the pins for a couple of seconds and prompt the user to check or replace the connection.
Problem solved!

Lets not forget this is the same NVIDIA that disabled the hotspot sensor. They probably did both of these on purpose, presumably
