One cable to rule them all? Admittedly, it's a bit of a mess with the many combinations of 12V 6- and 8-pin power connecter headers for graphics cards.

"2VHPWR" is the forthcoming PCIe Gen5 graphics card specification. In its complete arrangement, the cable can handle up to 600W of electricity. In addition, 450W, 300W, and 150W modes will be available. New papers provide the format of the Sense0 and Sense1 sideband signals. When both signals are grounded, the GPU will produce 375W of power and a maximum sustained output of 600W. If those signals are open, the GPU will initially get 100W, with a maximum of 150W during load.

Several power supply manufacturers have already indicated that their initial products would be compliant with the new standard. However, when it comes to graphics cards, NVIDIA's flagship RTX 3090 Ti Founders Edition was intended to be the first to have this sort of connectivity. However, NVIDIA has not released any information on a probable launch date for this device since its unveiling at CES 2022 in early January.
