After Nvidia released its high-end graphics card, the RTX 4090, several users reported that the graphics card’s 16-pin power connector (aka 12VHPWR) was burned or melted. Nvidia said this week that it was still investigating the issue and was unable to provide more information at this time. Testing with the Gamers Nexus found that loose connectors can easily generate heat of over 250 degrees in just a few minutes, causing them to melt and produce smoke. It argues that the problem was the result of a combination of user error and design oversight. The 12VHPWR connector is more prone to unseated errors than the older 6-pin and 8-pin PCIe power connectors because it lacks a mechanism for perceptual confirmation of seating. The RTX 4080 graphics card that just went on the market uses the same 12VHPWR connector and is believed to have the same hidden danger. US users have filed a class-action lawsuit against Nvidia on this issue.
