After it transpired that Nvidia-supplied 16-pin 12VHPWR adapters may soften if improperly mated with the GPU, a number of producers launched their customized 12VHPWR adapters designed to be extra dependable. Apparently, no less than certainly one of such adapters failed and melted when used with a GeForce RTX 4090 graphics card, in line with a Reddit submit. CableMod, the producer of the machine, promised to interchange the product.
A redditor named Humble-Good-654 posted an image of his 12VHPWR cable adapter that was clearly melted. He mentioned that he inserted the adapter accurately till he heard the press and the machine functioned with out issues for 2 months. Among the different Redditors mentioned that the cable was not inserted correctly, which is why it failed. Certainly, a few of the marks on the cable’s connector appear to point that it was plugged in correctly, however it may have wiggled unfastened after set up.
In the meantime, CableMod mentioned it will change the unit anyway. “Very sorry about that – please attain out to our help and we are going to make it proper with you,” a assertion by CableMod reads. “Our merchandise include service and we assist each buyer out.”

After investigating about 50 instances of overheated and melted 16-pin 12VHPWR cable adapters, Nvidia mentioned {that a} widespread concern was that the connectors weren’t absolutely plugged into the graphics card. The corporate prompt plugging the dongles earlier than putting in the graphics card into the motherboard.
Plugging in energy connectors correctly is extraordinarily necessary since nearly all cables can overheat when linked poorly. In the meantime, it’s critical to correctly plug within the connector on Nvidia’s flagship $1,599 product because the graphics card can draw as much as 450W of energy from the PSU, and transferring such an enormous quantity of energy requires high-quality cables and strong connectivity.
For now, we’ll have to attend and see if CableMods shares any details about the failed connector. Fortunately there have not been many studies of failed connectors with Nvidia’s connectors currently, a development we would prefer to see proceed.
