Probably Bound to Happen: Increased Power Draw for DLSS 5 Reportedly Claims Its First Victim After a User Finds an RTX 5090 with a Melted Power Ada...

Soldering would fix the resistance issue, right, but what about the voltage imbalance between pins, it wouldn't fix that would it? I would think some kind of hardware would be needed on the PCB to regulate the voltage per-pin, IIRC NVIDIA removed this hardware function.

So you solder again every time it melts? Fun job!

Or just solder it right for the first time?

The excessive heating is caused by the bad connection / poor surface contact of the pins combined with load imbalance. If it's soldered then you remove a hole from the swiss cheese model.

Also plastic melts away at a lower temperature than solder melts at.

Right but because testers ignored them then.. doesnt mean you can ignore them now.

Right, but if it could be ignored before but not now, that means this connector is worse with no safety margin.

Thats like running a 5090 and high end system with multiple drives on a 800 watt chinesium power supply that is 80 plus bronze but nowhere to be found on the registry.. it might work... or you might need the fire department.

Undersizing your power supply is a choice. With the cable you have no choice. If I could replace the connector with four PCIE power cords I would, but I can't. You shouldn't need to buy a $150 gizmo to prevent your $10000 GPU from catching fire.

The imbalance seems to be caused by poor connection between one or more pins and another pin picks up the slack. Soldering the connection would ensure all pins have a solid connection which should eliminate the imbalance issue which would then eliminate the heat.

On my 5090 I have one pin that's drawing an excessive amount of power and another that's not. I suspect the one that's not drawing a lot of power is a bad connection somewhere which causes the other one to compensate.

It shouldn't melt since it wouldn't get hot anymore. The connector on the GPU itself is soldered to the PCB and it doesn't melt because the the heat doesn't build up there due to a good solid connection. That would then extend to the newly soldered cables.
