IT House March 3 news, Intel recently exposed the next generation of graphics PCI-Express 5.0 power cord official specifications.
According to the PPT released by the leaker @momom_us, the official name of the upcoming PCIe Gen5 graphics standard is "12VHPWR", and the Intel data responsible for defining the ATX specification shows that the interface will support 4 power configurations, which are 150W, 300W, 450W, and 600W.
In addition, the PPT shows the binary configuration of sense0 and Sense1 sideband signals. When both signals are grounded, the start-up power supply is 375W and the maximum continuous power supply is 600W.
In addition, breaking news confirmed that the power supply interface was not compatible with existing 6pin and 8pin cables due to different contact spacing.
IT Home has learned that several power supply manufacturers have confirmed the introduction of PCIe 5.0 interface power supply, to achieve a single port 600W power supply, the need for 12 + 4 pin interface, 4 additional pins is the data signal interface, must be fully compliant with PCI-SIG's "12VHPWR high power connector (H+)" standard, that is, the new high power interface for the next generation of GPUs.
It is also reported that the next generation of NVIDIA RTX 40 "Ada" graphics cards will be equipped with this 12+4 pin interface.
