Possibly the first instance of Asus' anti-melting 12V-2×6 power cable…err…melting shows up, adding more fuel to the fire that is Nvidia's connector
Normally I'd suggest burning such things to the ground but they're doing that themselves.

Two months ago, Asus announced the ROG Equalizer, a power cable for certain Nvidia RTX graphics cards designed to banish the fear of melting connectors once and for all. Well, perhaps not completely so, because it seems we now have the first case of a melted ROG Equalizer cable.
As posted on ChipHell and reported by Uniko's Hardware on X (via Videocardz), there's admittedly very little information to go on, other than a crystal-clear picture of a seriously fried connector at the end of an Asus ROG Equalizer cable. Three of the six power pins look properly scorched, with one showing a considerable degree of melting in the plastic housing.

However, there's no indication as to what PSU and graphics card this cable was plugged into, nor the circumstances as to how the melty-melty all came about, so the one thing we can't do right now is point our fingers at Asus and go 'Ha! Your cable is rubbish!' Well, we can, but we just can't use this solitary picture as evidence for such a judgment.
If you're unaware of what all the hoohar is about Nvidia's 12VHPWR (and the subsequent 12V-2x6 design update) connector, let me give you a quick explainer. In order to have its graphics card use gopping great globs of power but also not require lots of big connectors on the card's PCB, Nvidia designed a compact system to be used instead of the traditional 8-pin PCIe system.
A precursor to 12VHPWR first appeared on certain RTX 30-series cards, such as the RTX 3090 Ti and 3060 Ti Founders Editions. This design just comprised twelve power pins (six +12V, six ground), but the iteration of the design that was approved by PCI-SIG and adopted into the PCIe specifications also housed four more pins for sensing.
That format first showed up on Nvidia's RTX 40-series, and almost immediately, reports of melting connectors appeared from owners of GeForce RTX 4090 cards. So much so that it resulted in a class action lawsuit against Nvidia being filed in 2022.
The problem is quite simple. A full load, an RTX 4090 can use up to 450 W of power, but distributed across six pins, each one only has to deal with 6.25 A of current. However, should one pin fail in some way, or the graphics card draw more current in one or two pins than the others, the resulting load imbalance can push the current over the 12VHPWR's design rating of 8.33 A per pin.
