Reports began to appear on the Internet that the 16-pin connector in the new GeForce RTX 4090 from NVIDIA is starting to melt and burn out. Reddit users posted photos (1, 2) of molten 12VHPWR connector from video cards manufactured by ASUS and Gigabyte, reports Wccftech.
The power cable is included and meets NVIDIA’s official specifications, as indicated by the company’s logo. There have been concerns in the past that bending or over-stressing the cable could lead to abnormal temperatures that could eventually cause similar problems.
Looking closely at the photos, it looks like the short is around the main 12 pin pins under the four extra pins on top. But looking at the adapter, it almost completely burned and melted.
A Reddit user reports that he was playing Red Dead Redemption 2 on his NVIDIA GeForce RTX 4090 PC when his power connector caught fire. He also states that the problem could be a faulty cable and he will send it to the dealer for a replacement. Therefore, there is still very little information about the possible causes of the problem and it is difficult to say how widespread it may be, taking into account only the beginning of GeForce RTX 4090 sales.
However, it is worth noting that NVIDIA’s 16-pin power cable for GeForce RTX 4090 video cards is quite thick and difficult to place in small PC cases. Therefore, users have to bend the cable strongly to close the case panel, which is not recommended as it may cause the adapter to heat up and catch fire.
Specialty cable manufacturers and modding companies are trying to solve this problem by offering 90-degree connectors, which should be available later.
