It is reported that Nvidia RTX 4070 graphics card has started to use the improved power supply interface.

CTOnews.com July 5 news, NVIDIA RTX 40 series graphics card first used 12VHPWR interface power supply, power supply capacity increased to 600W. At the beginning of RTX40 series graphics card market, there were reports on the Internet that the power supply interface was burned, partly because of poor contact. NVIDIA and PCI-SIG have been working on improved versions with better latch systems and improved pinouts to ensure better connectivity between GPU and power supplies.

According to VideoCardz, NVIDIA's latest RTX 4070 graphics card has adopted the power supply interface of the improved sensing pin shown above. The new "12V-2x6" connector shortens the sense pins (the four data pins that define the wattage of the cable), a design that disables high power mode when the cable is not fully plugged in. In addition, MSI has deployed this new "12V-2×6" connector on its upcoming power supplies.

According to CTOnews.com previously reported, NVIDIA RTX 4070 and higher RTX 40 series graphics cards use this 12VHPWR high-power power supply interface, RTX 4060 series basically uses the traditional 8 pin power supply interface. It is recommended that users who use high-end RTX40 graphics cards connect the power supply interface strictly according to the instructions to avoid accidents.
