Discussions within online hardware communities continue regarding the troubled existence of the 12VHPWR connection standard, while revised technology is quietly being developed in the background. Last summer, PCI-SIG introduced the 12V-2x6 connector as an alternative power delivery method for high-wattage graphics cards. Recent reports from TPU indicate that the 16-pin design of the 12V-2x6 connector has been spotted on select NVIDIA Founders Edition cards, custom designs of GeForce RTX 40 SUPER graphics cards, and various new generation power supplies.
Today, Алексей (AKA wxnod) shared on social media an image of the newly revealed "H++" 12V-2x6 socket with a maximum power of 675W, along with a picture of the familiar "H+" 12VHPWR with a maximum power of 600W.
The fourth generation 16-pin design was introduced with Team Green's GeForce RTX-40 SUPER card series, although wxnod mentioned that some AIC GeForce RTX 4070 SUPER, 4070 Ti SUPER, and 4080 SUPER cards still utilize the H+12VHPWR interface. While the 12V-2x6 connector made its debut on a few Non-SUPER cards in 2023, the recent launch of the SUPER series last month marked a more widespread implementation. AMD has hinted at potentially adopting the Gen 5 H++ in the future, but there have been no significant updates on that front since last August.
A new generation 16-pin PCIe 6.0 power connector design has been associated with the upcoming NVIDIA RTX 50-series "Blackwell" GPUs, although rumors spread by Moore's Law is Dead have been debunked by Hardware Busters. It is anticipated that Team Green will stick with the "H++" 12V-2x6 connector for their next generation graphics card releases.
