After several weeks of calm complaints about melting power cables for GeForceRTX 4090 video cards began to surface again on the Internet. This time, we’re not talking about adapters for video cards but cables that CableMod makes. This manufacturer was the first to release custom power cables with a 12-pin, 4-pin 12VHPWR connector.
NVIDIA claims that the problem with melting power cables can be attributed to users connecting them incorrectly without properly inserting the 12+4 pin 12VHPWR connector into power connector. VideoCardz portal reports that the number of reported melts of power cables for GeForceRTX 4090 has decreased substantially following NVIDIA’s statement. This could indicate that the manufacturer of the card is correct.
Reddit user, however, reported that a non-standard cable had melted for the GeForceRTX4090. This was from CableMod which makes a variety of products for modders. According to the user, the CableMod CableMod cable was correctly used, with its connector fully inserted into the power connector of his video card. The cable was still able to be used, but it melted in the process. The power connector for the graphics accelerator was not damaged, which was a good thing for the owner.
CableMod quickly replied to this message. They indicated that in case of damage to your video card due to a malfunction or defect of the power cable the manufacturer is prepared to replace your graphics accelerator with a brand new one.
“We are saddened by this news. We will solve this problem by contacting our technical support. Along with our products, our service is also available and we are always ready to help our customers.CableMod representatives commented on the matter. We spoke with the owner and found that the card was not damaged. If the cables were causing damage to the graphics card we would be happy to replace it. This has been done in the past, when power cables caused damage on rare occasions.
It is admirable that the manufacturer was willing to resolve any problem quickly. VideoCardz says CableMod’s case with a non-standard melted power cable is the only one currently. Therefore, it will take time for CableMod to identify the exact cause.
