We’ve been talking about the 16-pin 12VHPWR power adapters melting on NVIDIA RTX 4090 graphics cards for the past couple of weeks now. While there are other adapters coming and you can even 3D print a tool that will protect the cables, the consensus many people had was to go out and buy a new ATX 3.0 power supply that has the 16-pin native 12VHPWR connector. This is a single cable that comes out of the power supply and connect right into the RTX 4090.
Well it appears even buying one of these new, and very expensive power supplies won’t stop the 16-pin 12VHPWR connector from melting. According to a Facebook user he recently purchased the MSI GeForce RTX 4090 Gaming X Trio 24G graphics card and MEG Ai1300P power supply. He opted for the ATX 3.0 power supply because of the horror stories of the adapters melting. He said that he did not bend the cable excessively, but the native 16-pin 12VHPWR started to melt as you can see from the photos below.
MSI has reached out to him to replace both the graphics card and power supply. As we reported previously NVIDIA has been collecting adapters and cards that have had this issue, but they have yet to report the results of their investigation. While many people have thought the actual adapter was the issue of the failures, it seems it could go deeper than that, and the actual 12VHPWR power connector or even the RTX 4090 itself could be to blame.
Hopefully NVIDIA can shed more light on what is causing these failures.
