Would be funny if future GPUs end up with 24-pin motherboard connectors. Those things never get loose. Aside from spreading the resistance to many more pins. :D

I just noticed their are a number of automatic fire extinguisher products on amazon.

I wonder when they will start getting integrated into PC cases?

Some of the testers went to extremes trying to get the connector to melt but just couldnt. It appears to be a rare occurrence (relative to GPUs sold) which is sensationalized beyond the numbers reported. The testers views vary as to what could be the cause though.

It really appears that GN nailed it. You need to have it very loose in the socket, and pulled to one side. This also corresponds with nearly all the images of melted connectors where you could see witness mark show the were well out of socket when melting occurred.

Utter nonsense. The cablemod adapters were firmly seated, as witnessed when the plastic fused together. We have objective evidence of this from someone that actually knows what they're talking about.

Likewise, instances of burned connectors on the PSU side were neither "lose or pulled to one side".

Nah, it really isn't. Can you tell us another other tech product in recent history that had 6 instances of melting over the course of just 5 days?

And that's just the last time I randomly checked it. In reality there's a regular stream of this occurring.

Three new ones from the last 24 hours:

Interesting. The recent spike in adapter failures all seem to be Cable mod related. Which happens to be the only adapter that features 2 x 16-pin connecting points (M/F), thus doubling its resistance points and fail potential. If any weak connecting point on either side, it will draw more power, heat and of course melt. As demonstrated by the guy in comments saying his failed adapter was where the PSU cable joins to it (see below):

https://www.reddit.com/r/cablemod/comments/14s6jub

P.S. this does not mean that I think the 12vPHR connector is not a poor design, it is and needs to change to prevent any such occurrences no matter how small in number from occurring. And to ensure no manufacturing variances come into play that may cause any potential failures.

So it turns out the 4090 was also silently changed.

NVIDIA Now Ships GeForce RTX 4090 Founders Edition with Updated Power Connector

A few weeks ago, we reported that NVIDIA is already shipping its GeForce RTX 4070 Founders Edition cards with an improved 12VHPWR connector called 12V-2x6. However, today we learn that NVIDIA is also now shipping GeForce RTX 4090 Founders Edition with an improved 12V-2x6 connector. Thanks to the...

NV isn't spending money on this for fun or because they like us. Hmm, what other reason could it be? o_O

Yes because they prefer to avoid a recall and let their customers deal with the consequences of their mistakes. I bet they don't even test that exhaustively anymore.

No, I expect them to change those as well. It's a simple change as well. They just have to put the new connectors in the machine that solders on the components.

It's a bit more than that. They'd need to respin the PCB to put a thermistor right by the connector and modify the BIOS, so it's a reasonably large change.

They don't have to do that at all to solder a connector on there with shorter sense pins and potentially other changes that are internal to the connector itself.

I think that the chance is very small that they will do a redesign of the PCB. They didn't do one either for the 3090 when double density VRAM became available and they had a chance to fix the excessive memory temps due to VRAM being on both sides of the card.

Oh, yeah replacing the connector is pretty simple. Sorry I misunderstood you, the post and article you replied to was about using an external temperature sensor by the connector and software to shut down programs/the PC if temps get too hot.

Not gonna lie, but I'd buy a case that has its own built-in halon system.

I checked Tom's hardware and NV still haven't got back to them.

To quote the missing DLSS thread: why is NV dodging a straightforward question and not being forthcoming? o_O

We know NV changed the plugs, but still not a peep out of them. Meanwhile AMD confirmed their defective connector on reference 7600 cards.

In the comments section NorthridgeFix says they'll use the new connectors for repairs once they get their hands on them.
