NVIDIA thinks it knows why some GeForce RTX 4090s are experiencing power supply problems. 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 superlative graphics card from the green giant. This power monster requires a lot of power to operate and several users have reported cases of melted power connectors. In the middle of the game, they noticed that the graphics card power adapter had simply burned ; damaging the RTX 4090 in the process. A dangerous phenomenon and bad publicity for NVIDIA. The chameleon very 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
The manufacturer first of all wishes to reassure, explaining that it is only aware of “50 cases worldwide” of users who encountered this problem. NVIDIA’s first findings “suggest” that the problem is the same each time, namely that connectors are not plugged in correctly. “Our findings to date suggest that the most common problem is that the connectors are not fully seated on the graphics card”, says NVIDIA. The chameleon brand adds a photo to illustrate the problem:
Poorly connected, the 12VHPRWR power connector finds itself at the center of all attention. The NVIDIA theory has also been mentioned by certain specialists. Indeed, a poorly connected cable can cause 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 ensure 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 room for the cable. An additional difficulty as the RTX 4090 displays XXL dimensions. The use of an elbow connector appears to be a relevant solution; especially if your case is not large. 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 could soon evolve. NVIDIA studies ” other ways “ to ensure that “the connector is secure before turning on the graphics card”. This decision could definitively put an end to the controversy and reassure players.
