Kit contents and purpose

The FormulaMod Fm-NCK1 kit provides three sleeved extension cable types: one ATX 24-pin, three PCI-E 8-pin (6+2) and two EPS 8-pin (4+4), each 300 mm long with black connectors. It is intended for builders who want to route power cables neatly behind the motherboard tray while keeping the original PSU cables in place.

Compatibility check before ordering

Verify that your power supply uses standard ATX 24-pin, PCI-E 8-pin and EPS 8-pin outputs, because these extensions connect male 5557 to female 5559 and do not replace proprietary modular cables. Confirm there is enough clearance behind the motherboard tray for the 3 mm diameter, 18 AWG sleeved wires and the included polypropylene comb board.

Build integration

The extensions sit between the PSU cables and the motherboard, graphics card and CPU power inputs, adding 300 mm of reach for cleaner routing. Backward-compatible 6+2 and 4+4 pins let unused halves be tucked away, while the comb board lets you align cables in custom patterns without cutting or splicing.

Questions about this item

Does the kit include every cable I need for a typical ATX build, or must I buy any modular PSU cables separately?

The kit supplies one ATX 24-pin, three PCI-E 8[6+2]-pin and two EPS 8[4+4]-pin extensions plus a polypropylene comb board. They plug between your existing modular PSU cables and the components, so no extra modular cables are required.

Should I choose the straight, forward-bend or opposite-bend version for a standard mid-tower case?

Opposite-bend connectors angle away from the component, making the 300 mm length easier to route behind the motherboard tray in most mid-tower layouts. Straight works if you prefer a direct run, while forward-bend suits top-mounted PSU cut-outs.

What does the 300 mm length mean once the extensions are installed in a real system?

Each extension adds 300 mm to the reach of your PSU cables, giving enough slack to run ATX 24-pin, GPU and CPU power behind the motherboard tray and still attach the included comb board for a clean finish.
