Great, now even the RTX 4090 power connectors are starting to melt

By Nathan Drescher November 4, 2022

The Nvidia drama just got worse as Tom’s Hardware has reported on an Nvidia RTX 4090 power connector meltdown. This comes hot on the heels of stories of the GPU’s 16-pin power adapter overheating and melting.

“Maybe the first burnt connector with native ATX3.0 cable,” redditor u/nk950357 posted, along with a photo of a melted connector. The photo shows a 12VHPWR power connector from the RTX 4090’s own native power supply. This doesn’t appear to be a case of using a cheap third-party power supply.

It’s been a bad week for Nvidia, with nearly two dozen reports of melting 16-pin power adapters hitting the headlines. One 4090 even burst into flames. While the 4090 is a powerful graphics card, there’s clearly a problem here. AMD latched onto it and dunked on Nvidia during its RDNA 3 launch.

“There’s no need to for a new power adapter,” head of graphics at AMD, Scott Herkelman, said during the event.

Nvidia said it will replace any unit with a 16-pin power adapter that has melted, but now it seems there are new components melting.

The Reddit post follows the same post on Facebook from a user called Ricky TO. Although written in Chinese, the post explains he used an MSI GeForce RTX 4090 Gaming X Trio 24G card. He chose to go with the native ATX3.0 power supply rather than risk trouble with the 16-pin power adapter.

If you are using a GeForce RTX 4090 graphics card, you are probably feeling nervous right now. You can use an adapter and potentially void your warranty. Likewise, you may want to stick to your CPU’s integrated graphics for the time being until we hear more about this issue, and any potential fixes.

The problem could be much bigger than issues with the power supply. It could be an issue with the RTX 4090 itself, or at least something with the quality of the components that make up the 12VHPWR power connector. Nvidia hasn’t said anything yet as it continued to investigate. This latest melting component doesn’t make us feel any more confident.

Why I’m feeling hopeful about Nvidia’s RTX 50-series GPUs

I won't lie -- I was pretty scared of Nvidia's RTX 50-series, and I stand by the opinion that those fears were valid. They didn't come out of thin air; they were fueled by Nvidia's approach to GPU pricing and value for the money.

However, the RTX 40 Super refresh is a step in the right direction, and it's one I never expected to happen. Nvidia's most recent choices show that it may have learned an important lesson, and that's good news for future generations of graphics cards.
The price of performance
Nvidia really didn't hold back in the RTX 40 series. It introduced some of the best graphics cards we've seen in a while, but raw performance isn't the only thing to consider when estimating the value of a GPU. The price is the second major factor and weighing it against performance can often tip the scales from "great" to "disappointing." That was the case with several GPUs in the Ada generation.

CableMod’s adapters damaged up to $74K worth of Nvidia GPUs

Melted 12VHPWR connector made by CableMod for the RTX 4090.

CableMod's adapters were meant to fix the problem of melting connectors on Nvidia's top GPU, the RTX 4090, but it appears that things didn't go as planned. The Consumer Product Safety Commission has posted a notice that the CableMod 12VHPWR angled adapters are being recalled due to fire and burn hazards. More than 25,300 adapters are to be returned, and the affected customers are eligible for a full refund.

The connectors on the RTX 4090 have been melting ever since the GPU hit the shelves in late 2022, and so far, the only fix seems to lie in careful installation and picking the right PC case that can accommodate this monstrous card. CableMod's angled adapters showed a lot of promise, at least initially. Seeing as bending the cable can contribute to the overheating, an angled adapter should have been just the fix -- but unfortunately, the melting continued, even with the use of CableMod's solution.

Nvidia just fixed a major issue with its GPUs

If you've been unhappy with the performance of your graphics card lately, you might want to check out Nvidia's latest beta driver. This is a hotfix driver, which is pretty unusual for Nvidia, but it can be helpful if you've been dealing with micro-stuttering, both in games and on the desktop. The update addresses four issues in total, but to get it, you'll have to dig a little deeper than the standard path of updating your drivers.

Nvidia typically bundles bug fixes with its usual Game Ready drivers, as urgent hotfixes tend to be few and far between. However, this time, Nvidia chose not to wait any longer and pushed four updates for its GPU range. The new driver version, 551.46, may fix annoying stuttering issues.
