Common Applications

This 17.7-inch (450 mm) 12VHPWR extension cable terminates a single PCIe 5.0 16-pin (12+4) connector at the GPU end into two standard 8-pin PCIe male plugs at the PSU end. All twelve power conductors are 16AWG - the gauge mandated by the PCIe 5.0 12VHPWR specification. The 12+4 housing wires through the four PCIe 5.0 sideband sense pins so the GPU can read its assigned power budget. For cards whose envelope can be served from two 8-pin rails; higher-draw cards should use the 4x 8-pin variant.

Frequently Asked Questions

Q: What is the conductor gauge?

A: 16AWG on all twelve power conductors, per the PCIe 5.0 12VHPWR specification.

Q: Are the four 12VHPWR sense pins wired?

A: Yes. The 12+4 housing wires through all four PCIe 5.0 sideband signals.

Q: Should I use this on the highest-draw 600 W cards?

A: No. The 2x 8-pin input variant is sized for cards that can be served from two 8-pin PCIe rails; for cards specified up to the 600 W envelope, use the 4x 8-pin variant of this cable.

Q: How long is the cable?

A: 17.7 inches (450 mm) end to end.

Q: Are combs included?

A: Yes, cable combs ship in the box.
