I know it is not NVidia's connector and that it is just a spec they chose to adopt, but they took the flak for adopting the unproven design. This info is floating around on several sites, in that intel is proposing a revision to the 12VHPWR design to avoid future problems (better electrical connections). Per the picture below, the idea is to replace the dimpled metal connections with leaf springs. Seems like a solid way to fix the problem to me.

No idea how long a change like this would take to roll out.

Intel Readies ATX 12VHPWR Connector Revision to Address Improper-Contact Fire Hazards

Intel is preparing a revision to the design of the 12+4 pin ATX 12VHPWR power connector, specifically its male connector, to improve connector mating and retention; and to minimize a potential fire hazard asiring from improper retention or mating. The male connector design revision will retain...

A half dozen people melted a cord by not using it properly and now it's an issue? I've got a 4080 and a 4090. One uses the adaptor and the other is on an atx 3.0 Power supply with a dedicated 12vhpwr connector. Zero issues. I know a dozen people with the rtx 4 series, zero issues. I've bypassed the power limit and stress tested the 4090. Zero issues.

As long as the connector is fully inserted, there isn't an issue.

The problem is when people don't (though if you visually check you can remove any doubt). Supposedly the dimples can have so much friction that people "think" it is fully in when it isn't. Also, after many remove and install cycles the dimples can wear down. This design change would supposedly help address both scenarios.

Every electrical connector will wear out though. Doesn't matter what it is.
 
There is a clip, same as a 24 pin mobo and 6 pin molex and 8 pin pcie connector. Clip locks it in place. No dimples I can see. On either the ones that came with my GPU's or the one that came with my PSU.

Would I be safe in assuming the "6 pin molex" was a typo, or were you talking about the PSU end of a modular cable? :unsure:

As for the "clip"..... sure, that's why you've had no issues, and there's been a few melted connectors, because you pay close attention to engaging that clip, but not everyone does that. I mean, it's pretty damn easy to plug in various connectors(especially the 24pin mobo, or 8pin EPS), and not properly engage those clips..... I've done it many times, where the clip is engaged, but it didn't make a distinct click, so I've checked to make sure, and other times when the clip DIDN'T engage, so again, I've checked, and made sure the clip has made the proper connection. I've personally seen severe damage that a poor connection can cause, although it's been via cold solder joints, BUT an intermittent connection on this kind of plug can replicate the same situation as a cold solder joint. It almost seems like they need to include an unavoidable sticker on these connectors, with some sort of message proclaiming that, "YOU NEED TO MAKE DAMN SURE THE CONNECTOR IS FULLY ENGAGED BEFORE POWERING ON YOUR COMPUTER!!!"
 
Modern cards are also huge as stress the cables against the side panels and other things. O11 Dynamic and I literally couldn't put on the side panel until I ordered some 180 degree adapters (90s would have worked too of course) and the 40 series is around the same size and it isn't a small case.

However it makes me wonder if it isn't time to abandon the plastic clip locking mechanism and rethink that. Something more along the lines of a BNC connector with a very clear and positive twist lock on these increasingly high power connections.
 
As a side note

A quote from The Design of Everyday Things: Revised and Expanded Edition by Norman, Don

“It is time to reverse the situation: to cast the blame upon the machines and their design. It is the machine and its design that are at fault. It is the duty of machines and those who design them to understand people. It is not our duty to understand the arbitrary, meaningless dictates of machines.”

Ever hear the term Norman Door... this book i'm pretty sure is a keystone in a lot of product design courses still. He goes into it in multiple chapters how really the designs are at fault for a lot of problems that we tend to blame the user for.
Even website design if the user doesn't understand the snap decision should not be the user is dumb it isn't their fault, the design should be questioned to make it more human centric.

I have no problem with people who design things taking the time to work out the ins and outs. But lets face the truth. There will always be an army of idiots out there who will F things up, regardless of how well the thing is designed. Include instructions, include pictures, link to videos, it will not matter.
