At the end of last month, some owners of NVIDIA GeForce RTX 4090 video cards reported that they burned out the power adapters supplied with the adapter with 8-pin connectors on one side and a 12 + 4-pin 12VHPRW connector on the other. Now, on the Reddit site and on the Facebook* network, reports have begun to appear about cases of melting of the native 12VHPRW power connector of the ATX 3.0 power supply.
Despite the rather high cost of the GeForce RTX 4090, the accelerator is one of the best options for gamers. However, against the background of the current situation, consumers are not deterred by the price of the video card, but by the fact that the included 12 + 4-pin power adapter can be dangerous. Only on Reddit 18 similar cases with video cards from different vendors were registered. NVIDIA has responded to these reports and launched an investigation, instructing vendors to return faulty graphics cards to a lab to investigate the issue.
A member of the Reddit community used an MSI GeForce RTX 4090 Gaming X Trio 24G graphics card and a MED Ai1300P power supply. Since at that time there were already reports on the Internet about the possible melting of the complete video card adapter, the user decided to use an ATX 3.0 power supply with a native 12VHPWR connector. However, after a short use, the power connector of the video card still melted, as can be seen in the photos published by the user. According to reports, MSI contacted the user and offered to replace the graphics card and power supply.
NVIDIA has not yet made official statements on the results of the investigation. Perhaps the manufacturer is still trying to figure out the causes of the problem. At the moment, cases of melting of the 16 + 4-pin connector are known, but it cannot be ruled out that the problem is not in the design of the connector. It may turn out that the cause of melting is the 12VHPWR connector, low-quality components, or the video card itself in combination with various factors.
