Recently, a Reddit user shared a post revealing that the 16-pin power interface on their RTX 5090 graphics card melted during regular usage. The user emphasized that they had placed a high premium on power supply safety. They didn't just double-check to ensure the connector was securely plugged in; they also opted to run the system without a case to eliminate any potential pressure from the side panel. Despite these precautions, they were still unable to avert this problem.
