This RTX 4090 GPU has a huge problem. It caught fire


It appears that there might be a problem with the 16-pin connector that powers the Nvidia GeForce RTX 4090. According to a Redditor who owns the card, their GPU actually went up in flames, and parts of it have melted as a result.

Is this a more widespread issue, and should you keep a fire extinguisher nearby at all times if you own an RTX 4090?


One of the first reports of power-related issues with the RTX 4090 is here, and it’s a huge one from the get-go. A Redditor, reggie_gakil, posted on the Nvidia subreddit to announce that their Gigabyte GeForce RTX 4090 Gaming OC went up in flames — all due to the 16-pin power connector, they claim.

The RTX 4090 owner was playing Red Dead Redemption 2 when the GPU suddenly caught fire. The card was connected with the official Nvidia cable, but something must have gone wrong, because, in the end, both the power adapter and the power connector ended up melting. To prove the claim, the Redditor shared two pictures.

The photos show a melted power connector on the card’s PCB, as well as the power adapter in a similar state. It appears that the main 12 pins, located under the four extra pins, were the cause here. However, it’s hard to speculate at this point. The end result is clear, though, because almost the entire adapter has melted. Needless to say, the card is unusable.

This is certainly unfortunate, but as this is the first report we’ve seen, it’s important to take it with a little bit of skepticism and not assume that this will be a common problem with the RTX 4090. However, as noted by Wccftech, the 16-pin adapter cable is very thick, and that might (indirectly) be what caused this problem in the first place.

Fitting the cable alongside the enormous RTX 4090 into a less-than-roomy PC case is quite a challenge. As a result, many users end up having to bend the cable in order to even close their case. Unfortunately, this may have a negative effect on the temperatures and could lead to something as bad as what happened to reggie_gakil.

If you’re one of the early adopters of Nvidia’s latest RTX 40-series GPUs, make sure you’re building your rig inside a spacious PC case so that the GPU can comfortably fit. Cable manufacturers are already working on 90-degree angled connectors to help users with smaller cases fit their RTX 4090 without any risks.

As for the card in question, the Redditor will have to return it, so we may never know what really happened here. Let’s hope that Nvidia or Gigabyte will shed some light on the problem — if there actually is one.
