PCI-SIG is yet to formally introduce a revamped version of 12VHPWR connector that can solve the melting connector issue that has plagued GeForce RTX 40-series graphics cards several months ago. Igor's Lab claims that Nvidia's own GeForce RTX 4070 Founders Edition graphics board already uses the refined 12V-2×6 auxiliary power plug.
The main difference between the original 12VHPWR connector and the new 12V-2×6 plug are shorter sense pins, approximately 1.7 mm. This design ensures that the power header is fully inserted into the connector, otherwise the power supply does not activate high power modes, avoiding overheating and melting when a graphics card requires a lot of power.
