As the power of video cards grows, there is a need for a new power connector. Resource Igor’s Lab published the diagrams of the connector designed to work with PCIe 5.0. Its support may appear with the release of a new generation of AMD and NVIDIA video cards.
The 12VHPWR power connector includes 16 contacts: 12 power and 4 signal, and at the moment it is not clear for what purposes the latter will be used. The connector is designed to work with PCIe 5.0 graphics cards and does not support legacy peripherals. With the advent of 12VHPWR, it is assumed that there will be no need to use multiple PCIe connectors, as a result there will be less confusion with cables: manufacturers will not have to supply especially powerful video cards with two or three 8-pin connectors – one 12VHPWR is enough.
According to the drawings, 12VHPWR does not comply with Molex MicroFit standard. The power contacts are spaced 3 mm apart, while the existing 6- and 8-pin connectors have a distance of 4.2 mm. Its width is 18.85 mm, so it cannot be called miniature, although it clearly takes up less space than three 8-pin PCIe power connectors. However, it still has its own 12-pin connector from NVIDIA, which is 19 mm wide.
Each 12VHPWR power contact supports a current of up to 9.2 A, which at a bus voltage of 12 V will provide the connector with a total power of 662.4 W, although the official figure is capped at 600 W. Amphenol ICC has already indicated the connector on its website, however, calling it “the Minitek Pwr CEM-5 PCIe connector system” and noting that the maximum contact current is already 9.5 A. consoles, graphical interfaces, networks, servers and storage systems.
With the release of products based on the Ampere architecture, NVIDIA began to promote its own 12-pin connector, which was hardly used by manufacturers who prefer standard 6- and 8-pin solutions. With the advent of the 12VHPWR connector, manufacturers will have to either implement it in their products or provide customers with adapters.
