Regarding the 12VHPWR power connectors on the RTX 4090 melting, NVIDIA has issued a comment. According to the chip manufacturer, it is aware of 50 cases and is closely following the reports. Its results suggest that a common cause of these thermal mishaps is human error, specifically unsecured power connector plugs. This is consistent with what JonnyGuru, a power supply specialist for Corsair, mentioned a few days ago.
It’s important to remember that GamersNexus recently claimed that these problems could possibly be caused by a manufacturing defect (or at least worsening them). NVIDIA has reportedly refrained from acknowledging any such flaw for legal reasons. It only advises connecting the power dongle to the motherboard after first making sure the graphics card is securely and evenly plugged in.
Our research indicates that cables not being fully inserted into the graphics card is a prevalent problem. We advise inserting the power dongle into the graphics card first to make sure it is firmly and evenly plugged in before plugging it into the motherboard to help ensure the connector is secure.
We are looking on further options for testing the connector’s integrity prior to turning on the graphics card. Regardless of the cable or card being used, NVIDIA and our partners are dedicated to helping our customers and assuring a quick RMA process.
