I hope they get hit with a class action lawsuit and are forced to recall and properly fix these products before anyone dies as a result of their shoddy engineering.

EDIT: Plantiff dismissed it. Guessing they settled. Here are the court documents (alternately, shakna's links below include unredacted copies):

A GamersNexus article investigating the matter: https://gamersnexus.net/gpus/12vhpwr-dumpster-fire-investiga...
And a video referenced in the original post, describing how the design changed from one that proactively managed current balancing, to simply bundling all the connections together and hoping for the best: https://youtu.be/kb5YzMoVQyw
Sounds like it was settled out of court.

I’m curious whether the 5090 package was not following UL requirements.
Would that make them even more liable?
Part of me believes that the blame here is probably on the manufacturers and that this isn’t a problem with Nvidia corporate.
As a bonus, if the gauge is large enough, the cable would actually cool the connectors, although that should not be necessary since the failure appears to be caused by overloaded wires dumping heat into the connector as they overheat.
Or at least I think so? Was that a different 12VHPWR scandal?
I might actually be happy to buy one of these things, at the inflated price, and run it at half voltage or something... but I can't tell if that is going to fix these concerns or they're just bad cards.
Another problem is when the connector is angled, several of the pins may not make contact, shoving all the power through as few as one wire. A common bus would help this but the contact resistance in this case is still bad.
It is technically possible to solder a new connector on. LTT did that in a video. https://www.youtube.com/watch?v=WzwrLLg1RR4
Now imagine a magnifying glass that big (or more practically a fresnel lens) concentrating all that light into one square inch. That's a lot of power. When copper connections don't work perfectly they have nonzero resistance, and the current running through them turns into heat by I^2R.
And yet you speak of it like it's a representative model. Do you also use a Hummer EV to measure all EVs?
If I were interested in using an EV to haul particularly heavy loads, I might be interested in the Hummer EV and have similar questions that might sound ridiculous.
