Reddit reported the first case of PCIe 12 + 4 Pin (12VHPWR) powering a GeForce RTX 4090 burning and unplugging.
A gamer with ID u / reggie_gakil on Reddit posted an image on the NVIDIA subreddit of a PCIe 12 + 4 Pin (12VHPWR) burnt graphics card, the picture shows, including a PCIe 12 + 4 Pin (12VHPWR) and a connection of power supply on the PCB Both eventually fell into flames and melted.
Looking closely at the image, it appears that the problem occurs around the main 12 pins below the top four extra pins. But almost the entire adapter burned out and melted. The supplied cable confirms NVIDIA’s official specifications and has been reported earlier that bending the cable or applying too much pressure on the cable can cause abnormal temperatures which can eventually lead to problems like this.
The user reported that while playing RDR2 on his NVIDIA GeForce RTX 4090 PC, the graphics card suddenly caught fire and burned out the power connector. He also said it could be a faulty cable, although the cause of the problem cannot be pinpointed until more information is available.
I recently found that the PCIe 12 + 4 Pin (12VHPWR) adapter cable for the GeForce RTX 4090 graphics card is just too thick to handle in a smaller PC case and hits the side panels a lot. The user will therefore have to frequently bend the cable to close the panel, but even then this is not recommended as it may heat the cable and cause the adapter to burst and fire.
