Close-up of 12V-2X6 power supply interface: 'H++' design supports up to 675W power consumption

News from this site on February 20, the source wxnod recently shared detailed photos of the 12V-2X6 power supply interface, indicating that the new generation "H" interface design supports a power consumption of 675W, and compared the details of the "H" interface.

When NVIDIA launched the RTX 30 series GPU, it introduced a 16-Pin power supply interface, but the 12VHPWR interface was exposed to have a melting problem.

The PCI-SIG Alliance (responsible for developing new PCI standards, including connector design) released an updated 12V-2X6 standard in mid-2023.

NVIDIA’s new Founders Edition RTX 40 Super adopts the new 12V-2X6 standard, which is more safe and reliable.

Note from this site: Most of the new GeForce RTX 40 SUPER series graphics cards are equipped with the new 12V-2x6 power supply interface, among which RTX 4080 SUPER, RTX 4070 Ti SUPER and RTX 4070 SUPER are equipped with the newer Gen5 connector, but there are also a few models of RTX 4070 SUPER equipped with an ordinary 8-Pin PCIe power supply interface.

@wxnod showed a close-up of the "H" and "H" power connectors in the tweet. The new H design is based on the newer 12V-2x6 power connector revision and can provide up to 675W to the graphics card. Power output.

The two plugs look almost identical and users can see the difference by removing the top shield, marked "H" and "H" respectively.
