NVIDIA, RTX 4090 and 12VHPWR cable

NVIDIA RTX 5090 graphics cards are melting power cables (again) — but who's to blame for this recurring GPU nightmare?
Melting cables are, once again, affecting high-end NVIDIA graphics cards, as a small selection of disgruntled GeForce RTX 5090 Founders Edition buyers and content creators take to social media to report unreasonably high temperatures radiating from its 600W connector.
RTX 5080 power cable allegedly melts at PSU — Redditor reports another 50-series failure
According to u/Ambitious_Ladder1320, their RTX 5080 GPU flashed a red light while they were using their PC, which meant that a pin wasn’t seated properly. The user claimed that both GPU and CPU cables were connected properly, but to troubleshoot the issue, they switched off their computer and reconnected the GPU cable.
Surely not again: Worrying analysis shows Nvidia's RTX 5090 Founders Edition graphics card may be prone to melting power connectors
der8auer thinks none of the above. Using his own RTX 5090 FE, he loaded the GPU up with Furmark and found some worrying results using his own, higher spec 12V-2x6 cable, which had been in service for six months, and a 1600 W Corsair PSU.
Nvidia's RTX 5090 power cables may be doomed to burn
A rising tide of speculators are arguing that Nvidia's 16-pin 12VHPWR standard is designed with no safety factor, causing melting cables.
More Nvidia RTX 50 Cards Are Melting—It’s Probably The Cables’ Fault
Melting power cables was a persistent issue with Nvidia’s last-generation flagship, the RTX 4090. Its 450W power draw (with occasional spikes well above that) led to some power cables and GPUs overheating at the point the power connector plugs into the card.
Handful of users claim new Nvidia GPUs are melting power cables again
Reports from a handful of early adopters of Nvidia's new GeForce RTX 5090 graphics card are reporting that their power cables are melting (so far, there's at least one report on YouTube and one on Reddit,
Nvidia’s RTX 5090 power connectors are melting
Two owners of Nvidia’s new RTX 5090 Founders Edition GPUs have reported melted power connectors and damage to their PSUs. The images look identical to reports of RTX 4090 power cables burning or melting from two years ago.
Forget the GPU temp, even the Nvidia GeForce RTX 5090 power cable can hit 150°C
Thermal images of the new graphics card show one wire of the 16-pin 12VHPWR cable drawing over 20A and running at a high temperature.
