The person on reddit used a third party cable instead of the one supplied with the device.

It melted on both sides (PSU and GPU), which indicates it was probably the cable being the issue.
12VHPWR is a fucking mess, so please don't tempt fate with your expensive purchase.
What I've learned from this whole fiasco after owning a problem-free 4090 for over 2 years:
That said, I'm skipping this GPU generation (and most likely the next one as well). Hopefully in 2-4 years AMD or Intel will be on more level grounds with nVidia so that I can finally stop giving them money just to have good ray tracing performance.
Strolls nervously through room with RX 580...
I got lucky and picked up a 7900 XTX for a reasonable price last gen and it's been a really great card. I've got a couple systems coming up on needing a refresh (1080 Ti and a 2080 Ti) and I'm planning on upgrading both of them to a 9070 XT. I'm staying away from Nvidia until they start pricing their GPUs at prices actual consumers can afford instead of corporations looking to build AI farms.
That's bad, but that aside - It might be time to consider alternate power delivery to these cards. The power they need should warrant having a standard c13 plug directly on em or something.
Who would've thought.... 3DFX was apparently ahead of its time...
Is this the fabled Bitchin' Fast 3d?
A mini fusion drive, perhaps?
Power the house with it when not using the PC, but expect brown outs when gaming.
Four of the standard 8 pin PCIe power connectors would work well.
The new connector really should have used some large blade contacts to handle 50 amps.

It's poor design on Nvidias part. There is no load balancing.
So, when is the first party cable going to be launched? The device only hast an adapter shipped with it, which won't help you connect to the PSU 12VHPWR.
