Recently, a user faced a critical short-circuit issue while operating an RTX 4080 Super graphics card, which ultimately led to the graphics card's PCB being burned through. As per the user's account, a fire broke out in the GPU area almost instantaneously after the graphics card was mounted on the test platform. Upon disassembling the card, it was revealed that the short-circuit was primarily localized in the VRM (Voltage Regulator Module) power supply section of the graphics card. Specifically, the area near the 16-pin power connector suffered severe damage due to high temperatures, resulting in the formation of light-transmitting holes in the PCB. The root cause of the incident is suspected to be a capacitor malfunction or a MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) failure, which triggered voltage instability and current overload.

At present, the user's main concern revolves around the after-sales warranty. The user has stressed that the graphics card had never been disassembled prior to the incident and was only opened afterward to capture photos as evidence. However, this situation has complicated the process for the after-sales team to ascertain responsibility. This incident has significantly amplified consumer anxieties regarding the quality and safety standards of graphics cards.
