PCIe 5.0 is just around the corner, debuting on Intel’s new Alder Lake platform with the new 600-series motherboards powered by the Z690 chipset, which shakes PCIe 5.0 slots and DDR5 memory support.

We’re now hearing about a new PCIe 5.0 power connector that would be a leap from what we have now with a new PCIe Gen5 power connector teased. The new PCIe 5.0 power connector would offer up to a whopping 600W of power, quite significantly up from the 150W offered over the current 8-pin PCIe power connector.
The new PCIe 5.0 power connector has 16 lanes (12 power, 4 signal lanes) and is a brand new connector. You can see the 12 power lines, but the strange new 4-signal line position under the 12 power lines is new. This new connector has a smaller distance than the current connector, down to 3.0 mm from 4.2 mm. The new connector is 18.85 mm wide, making it much smaller than dual and especially triple 8-pin PCIe power connector setups.
That means we can have future GPUs with a single, smaller power connector that provides up to 600W (and more) of power over a single cable. PCI-SIG says that each pin can handle 9.2A power, which means a total of 55.2A at 12V with a maximum power of 662W, even though the specification itself is 600W.
As VideoCardz points out, some manufacturers, including Amphenol, have started listing the specifications for the new 12VHPWR connector, explaining: “Amphenol ICC introduces Gen 5, Minitek; Pwr PCIe; connector system. This new introduction CEM 5.0 PCI Express; 12VHPWR extra hybrid connectors and cable assembly support 600W GPU cards “.
The 12VHPWR connector is not designed to fit older PCI Express. 2×3 and 2×4 12V auxiliary power connectors. , 20 mm pitch. The new PCIe® connector system (CEM5) is designed for power applications with a current of up to 9.5A / pin (12 pin current) and the 4 signal pins that support signal transmission “.
- Rated current up to 9.5A per Contact with all 12 power connectors and 4 signal connectors
- Fully insulated terminals
- Positive locking on the housing with low thumb lock
- Low level of contact resistance: 6m max.
As VC points out, the 12-pin PCIe power connector that NVIDIA uses on its GeForce RTX 30 Series GPUs is actually useless with this new high-power PCIe 5.0 connector.
We could see NVIDIA using the new PCIe 5.0 power connector on its new flagship GeForce RTX 3090 Ti or RTX 3090 SUPER graphics card that has been teased recently and was due to arrive in January 2022. I do not think these cards will use 600W of power , but gimme, gimme, gimme new Ada Lovelace and RDNA 3 graphics cards with up to 600W and I will be a happy man.
