Here we go once more: Half a yr after Nvidia’s final official assertion relating to broken RTX 4090 cable adapters, new instances point out the issue hasn’t pale. The blame has been handed between Nvidia, person error, and the specification writer. Switching to ATX 3.0 energy provides continues to be the most secure wager.
At least three new studies of melting 16-pin adapters for Nvidia’s flagship GeForce RTX 4090 graphics card appeared on Reddit this week. The complaints may sign one thing continues to be flawed with the connectors six months after the controversy emerged.
The issues began in October when a number of 4090 house owners mentioned their energy cables had burned or melted. In November, Nvidia acknowledged 50 instances worldwide, saying the customers had improperly related the adapters. However, Igor’s Lab questioned the soldering high quality of the provided adapters.

The RTX 4090 makes use of 16-pin 12VHPWR connectors and natively helps ATX 3.0 energy provides. Users who do not need to spend additional to improve from their ATX 2.0 PSUs can use the bundled adapters on their 8-pin connectors.
One of the brand new incidents occurred after round six months of use. The person claims to have set the connectors accurately and securely. Similarly, a second person claims his properly-connected adapter went up in smoke about six or seven months after set up. The person primarily used the PC to coach AI fashions somewhat than play video games. A peculiar side of the second report is that the affected PC incorporates a second RTX 4090 that hasn’t skilled any issues.
A 3rd report comes from somebody utilizing a third-party Corsair SF750 platinum adapter. Assuming it was accurately related, this occasion may counsel that the adapter is not the issue. Even stranger is that the person restricted the GPU to 70 % energy and paired it with a modest Ryzen 7600 CPU, so the PSU definitely wasn’t overtaxed.
Reports of 4090 connectors melting or burning in ATX 3.0 provides have not appeared. So one of the best safeguard in opposition to the difficulty might be to keep away from utilizing any adapter and easily improve to an ATX 3.0 PSU, which most likely would not price a lot additional in comparison with the $1,600 graphics card. Those who cannot keep away from utilizing the adapters can verify the standing of their 16-pin reference to a brand new characteristic in GPU-Z.
