People are letting their hatred of Nvidia blind them to what happened here, a customer upgraded from a 4090FE to 5090FE, they were using a 3rd party ASUS 12VHPWR cable and didn't realize the 5090FE actually uses 12V-2x6 not 12VHPWR, while the port is the same the pins are different lengths.
End of the day PC power cabling is such a shambles with things that look standard but are not so you should only ever really use the cables that came with the product if you don't want to risk issues, especially with this specific ports poor history with 3rd party cables.
