GeForce RTX 4090 and melted connectors: NVIDIA explains

NVIDIA thinks it knows why some GeForce RTX 4090s are experiencing power issues. If the cables melt, it’s because they weren’t plugged in properly.

Remember. NVIDIA created a sensation at the end of September by formalizing the RTX 4090, the graphics card of all superlatives from the green giant. This power behemoth needs a lot of power to run, and several users have reported cases of melted power connectors. In the middle of the game, they found that the graphics card power adapter had simply burned out ; damaging the RTX 4090 in the process. A dangerous phenomenon and bad publicity for NVIDIA. The chameleon quickly announced the opening of an investigation to find out more about the abnormal overheating of this essential component.

A problem between the chair and the keyboard? Yes, according to NVIDIA

First of all, the manufacturer wants to be reassured, explaining that it is only aware of “50 cases in the world” of users who have encountered this problem. NVIDIA’s first findings “suggest” that the problem is always the same, namely that the connectors are not plugged in properly. “To date, our findings suggest that the most common problem is that the connectors are not fully seated on the graphics card”, claims NVIDIA. The chameleon mark adds a photo to illustrate the problem:

Badly connected, the 12VHPRWR power connector is at the center of all attention. NVIDIA’s theory has also been mentioned by some specialists. Indeed, a badly connected cable can lead to a short circuit and overheating of the connector. To avoid this problem, NVIDIA recommends of “plug the power connector into the graphics card first to make sure it is firmly and evenly plugged in, before plugging the graphics card into the motherboard”. Let’s also not forget that it is also important to leave enough space for the cable. An additional difficulty when the RTX 4090 displays XXL dimensions. The use of an angled connector appears to be a relevant solution; especially if your case is not large in size. This avoids twisting the cable or exerting too much pressure.

Towards a new version of the connector?

Criticized since the announcement of the GeForce RTX 40×0, the 12VHPWR connector may soon evolve. NVIDIA is studying ” other ways “ to make sure that “the connector is securely attached before powering up the graphics card”. This decision could definitively extinguish the controversy and reassure the players.
