Extension Cable for 12VHPWR GPU Power

The Formulamod Fm-NCK3 is a 300-millimetre internal power extension designed for graphics cards that use the 12VHPWR connector. It adds length between the power supply’s existing PCIe 6+2-pin output and the GPU’s native 12VHPWR input, helping builders route cables cleanly in mid-tower or full-tower chassis.

Braided 18AWG Construction With Adjustable Combs

The cable uses 18AWG copper conductors wrapped in a braided nylon sleeve for stable power delivery and a uniform look. A pre-bent structure holds a consistent curve after installation, while the heat-shrink-free design avoids bulky junctions. Included cable combs are fully adjustable and removable, letting you align each wire for a tidy finish.

Extends Existing PSU Cables — Not a Replacement

This product only extends the original modular cables supplied with a standard ATX power supply; it cannot connect directly to the PSU itself. The jump is worth it when the stock GPU cables fall short of a clean routing path or when you want a sleeved appearance without replacing the entire PSU loom. Builders who need a direct PSU-side modular cable should look elsewhere.

Questions about this item

Does the 12VHPWR connector support the full 12-pin PCI-E Gen5 interface?

Yes, the female 12VHPWR end accepts the 12-pin PCI-E Gen5 plug from a modern graphics card, extending the existing PSU cable by 300 mm.

Will the 300 mm braided cable with pre-bent structure fit behind a mid-tower motherboard tray?

The 11.8-inch length and pre-shaped curve are designed for standard mid-tower and full-tower routing; the combs are adjustable to keep the bundle tight against the tray.

How do I install the extension without reversing the male and female ends?

Plug the 6+2-pin female connector onto the PSU's native PCI-E cable first, then connect the 12VHPWR female end to the graphics card; the keyed sockets prevent incorrect insertion.
