12V-2X6 "H++" GPU Connector Touted to Safely Deliver 675 W

Online hardware communities continue to discuss the 12VHPWR connection standard's troubled existence , while revised technology gets worked on—quietly—in the background. PCI-SIG's 12V-2x6 connector was first revealed last summer, signalling an alternative power delivery method for high-wattage graphics cards. Past TPU reports show that the 12V-2x6 16-pin design has already popped up on select NVIDIA Founders Edition cards, GeForce RTX 40 SUPER custom graphics card designs , and various new generation power supplies . Earlier today, Алексей ( AKA wxnod ) took to social media and posted an image of the freshly deshrouded "H++" 12V-2x6 (max. 675 W) socket, as well as a shot of the familiar "H+" 12VHPWR (max. 600 W).

This fourth generation 16 pin design rolled out with Team Green's GeForce RTX-40 SUPER card series, although wxnod notes that exceptions do exist: "Some AIC GeForce RTX 4070 SUPER, 4070 Ti SUPER and 4080 SUPER cards are still using the H+12VHPWR interface." As mentioned before, 12V-2x6 debuted on a few Non-SUPER cards back in 2023, but last month's SUPER series product launch marked a more comprehensive rollout. AMD has indicated that it is considering an adoption of Gen 5 H++ in the future, but we have not heard much on that subject since last August . A new generation 16-pin PCIe 6.0 power connector design was linked to the upcoming NVIDIA RTX 50-series of "Blackwell" GPUs, but Hardware Busters has refuted rumors generated by Moore's Law is Dead. Team Green is expected to remain faithful to "H++" 12V-2x6 with the launch of next generation graphics cards.
