NVIDIA Says That It Is Still Continuing to Investigate Reports of Melting 12VHPWR Adapters

[Peter_Brosdahl]

It has been roughly three weeks since the first reports of melting 12VHPWR connectors and NVIDIA says that it is still investigating the matter.

See full article...

One odd thing is that some people are stating that the MSI instructions are incorrect because they say they plugged the wrong end of the connector into the power supply. I'm not sure if there is an incorrect way as I looked at my FSP instructions and nothing is noted.

 

[Peter_Brosdahl]

Yeah, and people on Reddit were joking about the MSI instructions in that they only highlighted the PSU connector and nothing about the graphics cards which is what the majority of the reports have been about.

Maybe that was what they were talking about in the thread I was reading as well. Just up to early and misinterpreted what they meant.

An interesting detail to note is that there are no Founders Edition graphics cards on the lists

Yeah, about that, that is no longer true.

I guess the so-called "experts" are hiding now! Where do they find these clowns analysts?!

Yeah, about that, that is no longer true.

Fully Connected 16-Pin Connector On The NVIDIA GeForce RTX 4090 Ends Up Melting Too

A fully connected 16-Pin '12VHPWR' connector on the NVIDIA GeForce RTX 4090 has melted & we also get our first Founders Edition case.

Edit: the site above mentions an engineering change request (ECR) of the 12VHPWR cable by PCI-SIG, and links to the review zone. I'm uncertain of the significance, however.

12VHPWR Cable Plug Update ECR
*Please note, this ECR is an ECR to address a system-side shroud design. This is unrelated to high power connections.

• Review period closes on Tuesday, December 13, 2022.

No worries. Most sites are just regurgitating stuff with this but I am trying to connect the dots hence why I include extra things and then:

I thought it was odd that no FEs were listed. Sure, they could've had a better connector on the card but if that isn't the issue then it won't matter, and again why I leave my own hooks. I do come from a family of hunters and fishermen..

It's all good. I posted about this in the AIC thread and went a little deeper for this particular post. The change is for the shroud around the "sense" data pins and is said to not affect whatever is happening with his.

I will say for all concerned, the bit about user error may have some weight. As I have 2 3090 Ti's, and many benchmarks show them using over 450W with a 12-pin to 3x 8-pin adapter. I've been watching them closely. For the hybrid, I don't have to OC it as it already clocks high. For the air-cooled card, I've been gaming, in particular CP 2077, and using Precision X1 for a maximum boost along with the 107% power limit boost, and a mild core/mem OC to force it a bit further. I'm not going to waste time with TPU-Z as Igor also had an article about TBP vs actual power at the wall and so on but I can tell you it's been fine. However, since this is in an open chassis I can walk up and touch it, at the GPU connector, and tell you it's warm to the touch. It has the better part of 70 mm straight to the card and at the PSU. Not that it matters though and not something anyone should be doing (touching while live or with a PSU that hasn't been discharged).

Since this type of connector will "clip/snap" even without fully being inserted, I've witnessed it, this is something to be concerned about. I'm paranoid enough that I worry about such things and even if I hear that click I'm going to inspect it further until I believe everything is right. When I installed my cards I saw this and simply worked with it until I felt it was right. So far, so good.

You really do have to push down extra hard to connect the adapter into the video cards I'm finding, what was typical force prior on 8-pin connectors is not going to cut it now, you have to put even more forced to really make sure it's connected all the way. I do see this as a big issue, I don't think people are doing that, they are used to using a certain amount of force for decades, but now, you have to use more and make sure it's fully flush, it's more effort, and this is a learning and educational thing.

Doing a post right now that includes this and much more info from Igor. He's really gone all-out in researching it and in contact with both NVIDIA and its partners.

Thanks! I'll watch it tonight when I get home.
