Common Applications
This FormulaMod 12VHPWR cable is a 17.7 inch (about 450 mm) male-to-female extension that adapts an existing PSU's pair of 8-pin PCIe outputs to a single PCIe 5.0 16-pin (12+4) connector on the GPU side, sized for the RTX 5090, RTX 5080, RTX 5070, RTX 4090, RTX 4080 and RTX 4070. Conductors are 16AWG tinned copper with alloy copper terminals rated for the full 600 W of the 12V-2x6 / 12VHPWR specification, and the cable is finished in high-density nylon braid. The 16-pin end uses a pre-bent boot to reduce mechanical stress on the GPU port. Three pre-installed cable combs hold the run flat for clean management.
Frequently Asked Questions
Q: Is this a PSU cable or an extension?
A: It is a male-to-female extension: the 16-pin (12+4) end plugs into the GPU and the 2x8-pin female end accepts your existing PSU PCIe cables. It does not connect directly to a modular PSU port.
Q: Which cards does it support?
A: It is sized for the RTX 5090, RTX 5080, RTX 5070, RTX 4090, RTX 4080 and RTX 4070. Cards with peak draws above 600 W or that ship with 4x8-pin adapters may prefer the 4x8-pin variant.
Q: What is the conductor and connector rating?
A: 16AWG tinned copper conductors with alloy copper terminals, rated to the full 600 W of the 12V-2x6 / 12VHPWR specification.
Q: How long is the cable?
A: 17.7 inches (about 450 mm) end to end.
Q: Does it include cable combs?
A: Yes. Three pre-installed cable combs hold the wires in a clean parallel layout.
