NVIDIA has started to equip the reference version of its flagship GeForce RTX 4090 graphics card with an updated 12V2x6 power connector that is protected against melting. The information was shared by a Reddit forum user who recently purchased this accelerator from NVIDIA Founders Edition.
Although NVIDIA has not yet announced any official changes to the 12 + 4-pin power connector for its GeForce RTX 40 series graphics cards, it has recently become known that some models of the Ada Lovelace generation accelerators are already shipping with a new connector.
One of the key differences between the new 12V2x6 connector and the original 12+4 pin 12VHPWR is the shorter signal pins, which are more recessed in the cage in the new version. Changes to the design are believed to prevent incomplete mating of the connector with the power connector – nothing will work if the contact is loose. It’s the loose contact of the 12VHPWR connector with the power socket on the graphics card that can cause it to melt under load.
It was previously reported that some versions of the GeForce RTX 4070 and RTX 4070 Ti models are already equipped with the new 12V2x6 connector.
