The 12VHPWR and 12V-2×6 connectors are both designed to solve a real problem: delivering hundreds of watts of power to high-end GPUs over a single cable rather than trying to fit multiple 8-pin power connectors onto these GPUs. In theory, swapping two to four 8-pin connectors for a single 12V-2×6 or 12VHPWR connector cuts down on the amount of board space OEMs must reserve for these connectors in their designs and the number of cables that users have to snake through the inside of their gaming PCs.
But while Nvidia, Intel, AMD, Qualcomm, Arm, and other companies are all PCI-SIG members and all had a hand in the design of the new standards, Nvidia is the only GPU company to use the 12VHPWR and 12V-2×6 connectors in most of its GPUs. AMD and Intel have…
