Common Applications

This FormulaMod 12VHPWR cable consolidates three PCIe 8-pin outputs on a modular PSU into a single PCIe 5.0 16-pin (12+4) connector for current-generation graphics cards, including the RTX 5080, RTX 5070, 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 spec, and the cable is finished in high-density nylon braid for abrasion resistance. Total length end to end is 17.7 inches (about 450 mm) with a pre-bent boot to reduce stress at the GPU plug. Three pre-installed cable combs hold the wires in a clean parallel layout for tidy cable management in a windowed chassis.

Frequently Asked Questions

Q: Which graphics cards is this cable rated for?

A: It is sized for the GeForce RTX 5080, RTX 5070, RTX 4080 and RTX 4070, which use the PCIe 5.0 16-pin (12+4) power input. The RTX 5090 and RTX 4090 typically demand a 4x8-pin variant for full headroom.

Q: How long is the cable?

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

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: Does it include cable combs?

A: Yes. Three pre-installed cable combs hold the wires in a clean parallel layout.

Q: Is this an extension or a PSU-side cable?

A: It is a PSU-side cable: the 3x8-pin end plugs into modular PSU PCIe outputs and the 16-pin (12+4) end plugs into the GPU.
