Nvidia says it’s investigating two reports of RTX 4090 cards that have had power cables burn or melt. Reddit user reggie_gakil was the first to post details about their Gigabyte RTX 4090 issues yesterday, showing burn damage on the new 12VHPWR adapter cable that Nvidia ships with the RTX 4090. The connection on the actual card was also damaged and melted.
A second Reddit poster replied to the same thread showing off similar damage to an Asus RTX 4090 graphics card power connector.
“We are investigating the reports,” says Nvidia spokesperson Bryan Del Rizzo in a statement to The Verge. “We are in contact with the first owner and will be reaching out to the other for additional information.”

Nvidia initially moved to this new 16-pin power connector for its own RTX 3090 Ti cards, and it has now become a standard on the RTX 40-series GPUs across vendors. There are concerns that the 12VHPWR power connector, which is designed for new ATX 3.0 power supplies, could cause issues if it’s bent a certain way.
The 12VHPWR connector and terminals are a lot smaller than the previous generation, and cablemod warns that “it appears that bending the wires too close to the connector could result in some of the terminals coming loose or misaligning within the connector itself.” The site recommends not bending a connector vertically or horizontally, and instead having a minimum distance of 35mm from the connector before any bends occur.
That’s rather difficult in practice, with Nvidia’s adapter hitting the side panel in most modern cases. The original Reddit poster vertically mounted their RTX 4090, which means the cable could have bent before the minimum distance.
