Nvidia RTX 4090 GPUs Are Apparently Burning Power Cables

A growing number of users are reporting their Nvidia RTX 4090 – the company’s flagship GPU – is causing power connector melting.


Reports are gathering pace about issues stemming from the RTX 4090 graphics card. It seems the flagship GPU is causing power connectors to meet on a selection of PC setups. It does not appear the problem affects all PC builds, but it is unclear how widespread it is.

Certainly, owners of several setups and gaming PCs have discussed their experiences with the problem online. According to Reddit user reggie_gakil (via Windows Central), their power adapter melted when using the Nvidia RTX 4090.

In images to accompany the report, reggie_gakil shows the damage is more focused in the upper left corner of the connector. It does seem that the GPU is causing too much power to pass through the power connector, with more in certain parts.

Nvidia has responded to the growing number of reports with the following statement:

“We are investigating the reports. We are in contact with the first owner and will be reaching out to the other for additional information,” says NVIDIA's Bryan Del Rizzon to Tom's Hardware.

RTX 4090 Power

The RTX 4090 is the newest flagship consumer GPU from Nvidia and requires a huge amount of power. It draws a maximum of 450W but an overclocked version may go up to 500W. If the PC owner wants to overclock the 4090 manually, it can draw up to 600W or higher. All that power passes through a single connection.

In his post, reggie_gakil points out that his GPU was running at an optimal 400W while running Red Dead Redemption 2. A graphically intensive game for sure, but well within the capabilities of Nvidia's flagship… at least on paper.

Tip of the day: With a single registry tweak, it's possible to add a ‘Take Ownership' button to the right-click context menu that performs all of the necessary actions for you. You'll gain full access to all possible actions, including deletion, renaming, and more. All files and subfolders will also be under your name.

The Take Ownership context menu will set the currently active user as the owner of the files, though they must also be an administrator. They can then enter the folder or modify the file as they usually would.
