RTX 4090 12VHPWR cable appears to be very dangerous

It is indeed a really dumb design. For example, I have a Lian Li Evo Dynamic Mid Tower case which actually does provide a decent amount of width for a graphics card and the adapters. Currently have EVGA 3080 Ti in there which has PCIE Plugs on the top too, but the 3 cables do just fine in the space. If I was to get say a 4090/4080 or upcoming 5000 series (if they keep the same design), I am not certain it would fit without bending the cable too close for comfort.

And this is a case which has plenty of space for other GPUs, length or height. The whole design is just WTF from Nvidia.

I hear you. I recently switched out my ITX case with an Antec P10 Flux which is quite large (175mm from the MB to the side panel), but I'd probably still need a right angle adapter on there.

My son has this tower. We leave our computers on pretty much 24/7. I built his computer and his 2 cousins computer in June with a different case, no issues. All 3 has the corsair 1000 RM or whatever its called the new one.

Consumers should immediately stop using the recalled angled adapters and contact CableMod for instructions on how to safely remove their adapter from the GPU and for a full refund, including cost of shipping, or a $60 store credit for non-customized products, with free standard shipping.

Consumers will be asked to destroy the adapter and upload a photo of the destroyed product to https://cablemod.com/adapterrecall/. The instructions on how to safely remove the adapter are also located on that site. Once destroyed, consumers should discard the adapter in accordance with local laws.

The firm has received 272 reports of the adapters becoming loose, overheating and melting into the GPU, with at least $74,500 in property damage claims in the United States. No injuries have been reported.

When it all comes down to it. Having to plug external power to a pcie card that already receives a portion from the motherboard is silly. The power should all come from the motherboard. Its time that a new standard be created that would allow the motherboard to directly supply enough juice. Someone is going to killed in a house fire due to these connectors.

Motherboards would probably have to be radically redesigned to accomodate that much power, increasing costs. Not everybody is going to need that much power.

Besides video cards have been using external power connectors for a long time now. My 3dfx voodoo 5 5500 has a 4-pin connector for extra power and that card is from 2000.
People have been using 6/8 pin pcie connectors for years now without issue. It’s just this connector that has been having issues.

The NVIDIA RTX 4090 graphics card, launched in September 2022, continues to face serious issues with its power supply interface melting. NorthridgeFix, a GPU repair specialist, recently highlighted the persisting problem in a video that showcased a collection of damaged 16-pin power connectors from these cards. On average, the shop addresses malfunctions in 200 RTX 4090 units each month due to this defect. Originally, the RTX 4090 utilized a 12VHPWR connector, which has been prone to poor contact and subsequent melting. In response to the widespread issue, NVIDIA announced a transition to an improved 12V-2x6 power supply interface. Despite this upgrade, many units sold in the past two years still feature the older, problematic 12VHPWR connector.

The melting of the power connectors varies with the intensity of card usage. Some users report damage within months, while others may not notice problems for over a year. Graphics cards that are less frequently used generally show delayed onset of these melting symptoms.

That looks expensive...

Yeah, saw that and man this connector sucks.

Shitty situation. I looked at a couple of articles and didn't see it mentioned - How much does the repair cost when this happens?

Connector is way too small for that much power running through it. There isn't an issue with the other 4000 series cards, under the 4090.

I've been thinking whether getting a 4080S or 7900XTX some time this year, then I saw a video saying it's still an issue and nope, not putting my family in danger because of videogames, Nvidia has to fix their shit before I even think on going back to them.

Nothing wrong with that.

In terms of power delivery- whats the benefit of the Nvidia connector? Why not run 3x 8 pins like AMD?

I honestly wish they had just stuck with the triple 8 pin power connectors.
It doesn't bother me at all with my 3090. The connectors feel snug, secure, and beefy.

I think the issues lies on AI servers, it's waaaaaay more comfortable to arrange and maintain thousands of cards connected by a single cable each instead of 3 per card, that has been my assumption for months since that's Nvidia main point, for them gaming is secondary market already
 
My Corsair GPU power cable is sitting in the box waiting for the day I can buy a RTX 5090.
What are the odds that I will never get to use it? Either because they change the connector or I can't find the 5090.

I think 4080s runs on 320w - same as 3080 etc - it is the jump to 450w for the 4090 that causes the issue maybe?
