At present, NVIDIA’s GeForce RTX 40 series graphics cards based on the Ada Lovelace architecture are equipped with a 16Pin 12VHPWR interface. Compared with the 6Pin or 8Pin external power supply interface used in the past, the new interface seems to have higher connection requirements and is more fragile.
According to Wccftech, at present, when some users use a GeForce RTX 4090 graphics card to play “Red Dead Redemption 2”, the 12VHPWR interface on the graphics card overheats and catches fire, and even flames can be seen, and the plug of the cable is also damaged. The user indicated that the transfer cable used may have quality problems, and has contacted the manufacturer to request a replacement.
However, this is not a single incident. Other users have also posted photos of the damaged 12VHPWR interface of the GeForce RTX 4090 graphics card, and there are also signs of burnout. From the side, it confirms the concerns of many users before. Due to the excessive pressure on the cable due to the bending, the temperature is abnormal and eventually damaged.
In fact, the issue was reported to the PCI-SIG before Nvidia released the GeForce RTX 4090. After testing, it is concluded that if the cable is severely bent or connected/disconnected frequently, in some cases, it may be damaged by overheating or even directly lead to the melting of the cable. It is recommended that the cable be bent more than 3.5cm away from the plug.
Since the GeForce RTX 4090 graphics card itself is relatively large, if you use a 12VHPWR adapter cable and replace it with three or four 8Pin ports, it will take up more space. As a result, it is very difficult for many users to route the chassis, and it is easy to leave safety hazards, and accidents are inevitable.
