New 12-pin PCIe power connector accepts 600 watt video cards

Last year, Nvidia introduced the 12-pin power connection with the Ampere video cards, which can deliver 648 watts in a compact size. It now appears that the PCI-SIG is working on a new connection with comparable properties. So Nvidia’s 12-pin becomes a industry standard — but not quite.

Igor’s Lab claims that sources within the power and video card industry state that the PCI-SIG is a new ones standard under the name ‘high power connector’, or ‘H+’ for short. It is also called ’12VHPWR’ and is part of the PCIe 5.0 specification. By this, the organization does not mean the connection on your motherboard, and it is also not the same connection as that of Nvidia.

With a width of 18.85 millimeters, it is slightly smaller than that of Nvidia, which is 19 millimeters wide. The power pins are also smaller: 3 mm instead of 4.2 mm. It is therefore not backwards compatible with the existing connections. Still, it will take up less space than three (or more) regular 8-pin connectors, which can deliver 450 watts together.

Componentenmaker Amphenol ICC already has the connection on its website. Where Igor’s Lab mentions a current of 9.2 amps per pin, Amphenol is talking about 9.5 amps per pin. Also new are the four contact points that will probably have a measuring function.

With a theoretically feasible power of 600 watts, cards of all shapes and sizes should be suitable. Whether there are actually products (for consumers) with this connection in the offing is not yet clear, in any case it will present the necessary challenges for manufacturers of power supplies. It could also be that the connector will mainly be used for high-end server products.
