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

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.

In some cases, if the adapter was found to be the culprit, GPU manufacturers directed the unlucky customer to CableMod for refunds. This is because using it voids the warranty. As such, CableMod doesn’t just have to pay for over 25,000 adapters that are eligible for refund, but it’s also had to settle plenty of complaints and fund replacement GPUs for those affected.

“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,” said the U.S. Consumer Product Safety Commission.

The recall covers all CableMod version 1.1 adapters that were purchased between February and December 2023, both on Amazon and directly from CableMod. This includes the 90-degree and 180-degree variants, as well as the reversed adapters. The company will be refunding the entirety of the purchase, including shipping; those who prefer it can choose to get a $60 store credit for non-customized items instead.

This is grim news for CableMod, but the company has previously warned customers not to buy its adapters, going as far as to issue a safety recall in December 2023 — so this should come as no surprise. If you’re thinking of buying the GPU for yourself, we recommend avoiding third-party adapters. Installing the RTX 4090 isn’t easy, so you’ll need a case with plenty of space and careful cable management to make sure your $2,000 GPU doesn’t end up on fire.

This new GPU connector may finally kill the melting 12VHPWR
A hand holding the RTX 4090 GPU.

The 12VHPWR graphics card connector has made a name for itself for all the wrong reasons, with the component frequently melting and causing the death of many a GPU. Now, graphics card manufacturers are apparently testing a replacement that could finally put an end to the sorry saga.

The new version, dubbed 12V-2x6, can reportedly deliver up to 660W of power to a graphics card -- 10% more than the 12VHPWR. Despite that, testing has apparently shown it to be much safer than its predecessor.

The situation with melting RTX 4090 connectors just got more complicated

Nvidia's best GPU continues to melt, and even third-party adapters can't seem to prevent it from happening.  CableMod's adapter, which many had hoped would fix all problems, is now pinned as the cause of some of the instances of melting connectors. Unfortunately, using it voids the warranty on the GPU, as one unlucky user found out from MSI.

Reddit user Agentcamels reported on the MSI subreddit (via Tom's Hardware) that their RTX 4090 went up in smoke. We've heard of this before -- it's a seemingly never-ending saga of melting RTX 4090 connectors. It seems that they were playing Cyberpunk 2077 when they saw smoke. CableMod's 12VHPWR adapter was in use here, and that may have caused the meltdown; in any case, it appears that the adapter is now stuck to the GPU.

Here’s why I’m glad Nvidia might kill its most powerful GPU

A reliable leaker has just revealed that Nvidia might be abandoning the idea of releasing an RTX 4090 Ti. If the project hadn't been canceled, the RTX 4090 Ti would have ended up becoming the best GPU by a mile -- or at least the most powerful. That spot is currently held by Nvidia's own RTX 4090.

But don't worry -- if the report about the cancellation is true, it's not such a bad thing at all. In fact, it might be for the best for pretty much everyone involved. Here's why.
