After quite a long break since first reports saying there are problems with 12VHPWR connector which is used for GeForce RTX 4000 graphics cards appeared, NVIDIA has finally done some research and shared intermediate results.
According to the developers, overheating and melting of the power connector can occur if the user is not careful when plugging the connector in. Namely, when doing it not fully. In such cases, the contact area of the conductors decreases, which, taking into account the calculated power of 600 W, can lead to undesirable consequences. However, such cases are rare.
According to NVIDIA, the manufacturers of graphics cards received only about 50 applications stating the melting of 12VHPWR connectors. Considering that about 125,000 GeForce RTX 4090 graphics cards have already been sold, about 0.04% of owners of top graphics adapters faced problems.
To prevent possible connector problems, NVIDIA recommends pre-connecting the power cable or adapter before installing the graphics card in the case. And also additionally make sure that the connector is securely fixed in the final position.
Judging by the release, engineers are studying additional ways to ensure a secure connection of the connector before turning on the graphics card.
Problems with the possible melting of the connector on a very expensive graphics card, of course, do not inspire the potential buyers, as well as owners of GeForce RTX 4090. At the same time, the main competitor does not lose the opportunity for trolling.

Recently, Sasa Marinkovic, one of the heads of AMD’s gaming division on his Twitter wished everybody to stay safe this holiday season by using a photo of a fragment of a Radeon RX 7900 XT/XTX graphics card showing the standard 8-pin connectors for connecting additional power. However, it should be reminded here that new AMD graphics cards will go on sale only from December 13, so perhaps not everyone will have time to buy a powerful new model for holiday gaming battles.
