The 16-pin 12VHPWR connector that powers the Nvidia RTX 4090 graphics card came up with the problem of melting. Nvidia made a statement about the 12VHPWR power connector out of the box with the RTX 4090 graphics card. Stating that there was no problem in the connector design, the company announced that the cable melting problem was caused by the user.
Nvidia users blamed! Description of RTX 4090 power connector from the company
Nvidia made an official statement today about the melting of the power cables for the RTX 4090. The company claimed that around 50 people worldwide have experienced this problem and it was caused by users plugging in the cables incorrectly.
Reddit users announced last month that the power connectors for the RTX 4090 melted at the end of the cable and the graphics card’s connection port. The melting issue is caused by the power adapter that Nvidia shipped with the graphics card to make it compatible with older power supplies.
In September, the Peripheral Component Interconnect Special Interest Group (PCI-SIG) raised a possible overcurrent issue with adapters that Nvidia claims to have fixed. A study by Igor’s Lab revealed that the joints on the connector are fragile and inserting or removing them can damage the connections. Cable supplier CableMod warns that it is unsafe to bend cables over a short distance.
Nvidia RTX 4090 owners announced that they are suing Nvidia for cheating by distributing dangerous and defective adapters. Some users stated that they purchased an ATX 3.0 power supply to avoid problems with the 12VHPWR.
Although AMD partially admits that the new graphics cards cannot compete directly with the RTX 4090, it underlines that there is no need for additional hardware for use with ATX 2.0 power supplies. The Radeon RX 7900 XTX and XT will launch on December 13 for $999 and $899, respectively.
