NVIDIA might have a problem with some RTX 4090 catching fire

[EHW Ai]

I noted that, but don't feel it was extensive enough. That said, he did allude to the possibility it might require a lot more time, a lot more testing, etc.

 

In my not so humble opinion, a 20 minute influencer's video often proves little more than the fact they got free product from a manufacturer.

 

Anyway, see the following two applicable documents that separate the wheat from the chaff:

 

GS-12-1706 GENERAL PRODUCT SPECIFICATION
Minitek Pwr CEM-5 12VHPWR Wire to Board Connectors

GS-20-0704 APPLICATION SPECIFICATION

Furthermore, just in from r/nvidia:

I think my Asus 4090 TUF OC adapter is melting too

Had to disconnect my GPU to make space for the 13900k installation and I noticed that one of the pins looks melted. What should I do?

 

EDIT:

 

Here's pictures of how the cable sits in the case:

It has not been touching the side panel. I used all 4 of the connectors. PSU is EVGA 1200W P3 brand new. All stock settings - no OC or underclock.

 

EDIT 2:

 

An Nvidia rep contacted me to go over my system system specs. A call is scheduled for tomorrow.

 

I was offered to send my ASUS GPU direct to Nvidia in exchange for a FE GPU. I declined due to price difference.

...have two of the ones highlighted coming from Seasonic for my Seasonic PX PSUs, so everyone can (hopefully) sleep better at night now. I think I'm going to list my 4-into-1 adapter dongle set on the marketplace here so you folks can outbid each other in a frenzy...the money will come in handy for when the Galax HoF 4090 Ti comes out with two of the 12VHPWR connectors 

 

Now back to delicious gaming framerates on full eye candy

^chuckle, you can keep your dongle.

 

They're now saying it's the dongle NVIDIA supplied that's made by Astron Corporation that's the culprit. Igor's Lab shared some details (Google translate if you don't schpeak sharemany).

Good find ! Igor's 'full dissection' vid (also performed by others, like he mentioned) really shows what the problem is - it's not at the 12VHPWR connector 'receptable' on the card side itself, but that silly final bit in the dongle where the cables are soldered to...silly is an understatement; probably more like liability-producing engineering faux pas. The solution is really as stated above, get a full dongle-free 12VHPWR cable - preferably from your specific PSU's maker, or even from a respectable custom manufacturer.

Looks like the ride may not be over yet (read through this post):

 

 

Spoiler

 

 

But Teaktown claims Jensen flew to Taiwan for a different reason:

This news lines up with NVIDIA CEO Jensen Huang flying out to Taiwan to meet with TSMC (Taiwan Semiconductor Manufacturing Company) to nail 3nm wafers for its next-gen Blackwell GPUs... but maybe Uncle Jensen was calming AIB partners down as they're about to get reamed with returns, bad reviews from customers, and more.

 

Anyway, the he saids she saids appear to be propagating wildly.

So glad I didn't buy 4 series. I would be one of the guys with a lit dungeon.

...very glad I got my 4090 - Bonus: got it at entry-level pricing, and with big OC potential on top. It is not the Intel-spec connector on the card itself that is the issue, but the 4-into-1 dongle. As to said dongle, Seasonic is sending me (at no charge) a proper 12VHPWR 600W-rated single-strand designed specifically for my PSUs per approval email below. In the meantime, I will be careful (dongle has never been unduly bent, card is vertical mount).

 

Second pic below shows my 3090 Strix... 8-pin PCIe cables were bent too much, with the resulting partial melt (arrow)...card still works great, though, once I fixed the cable paths.

 

FYI, 4090 topics at extremehw.net have been a real eye-opener for me
