NVIDIA GeForce RTX 4090 Users Are Still Complaining about Burnt Power Cables: “12VHPWR Adapter Melted after Six Months”


The controversy surrounding NVIDIA’s GeForce RTX 4090 GPUs and the potential for melted 12VHPWR adapters seemingly refuses to die. Per a new roundup of alleged reports that has been shared online, one ASUS TUF Gaming GeForce RTX 4090 owner has claimed that their “fully connected” power cable burned up after 6 or 7 months, while another claims that they ran into a similar issue under the same time frame, presenting the usual and now-tiresome photos of a damaged connector. At least one more involves the GeForce RTX 4090 Founders Edition, which was paired with a Corsair SF Series SF750 Platinum PSU. NVIDIA’s last official update about melting power connectors appears to be from November 18, 2022, and it includes images that imply user error.

From an NVIDIA Support post:

We are actively investigating the reports. We are aware of about 50 cases globally.

Our findings to date suggest that a common issue is that connectors are not fully plugged into the graphics card. To help ensure the connector is secure we recommend plugging the power dongle into the graphics card first to ensure it’s firmly and evenly plugged in, before plugging the graphics card into the motherboard.

We are investigating additional ways to ensure that the connector is secure before powering on the graphics card.

NVIDIA and our partners are committed to supporting our customers and ensuring an expedited RMA process, regardless of the cable or card used.
