Kit Contents

The FormulaMod Fm-NCK1 kit supplies one ATX 24Pin extension, three PCI-E 8[6+2]Pin extensions, two EPS 8[4+4]Pin extensions and a polypropylene cable comb board. Every cable uses 18 AWG conductors inside a 3 mm nylon braid with insulated middle layers. Connectors are male 5557 to female 5559 in a straight orientation. Length is 300 mm per cable.

Who This Suits

Builders who need longer reach from a standard ATX power supply to motherboard, graphics card and CPU sockets will find the kit covers 24Pin, triple 8Pin GPU and dual 8Pin CPU requirements in one pack. The backward-compatible pin splits let unused halves tuck behind the tray. Buyers who want pre-bent connectors or lengths other than 300 mm should look at something else.

Build Integration

Each extension plugs between the existing modular cable and the component, so no PSU rewiring is required. The included comb board lets you align and separate individual wires for cleaner routing through grommets. The 3 mm diameter and flexible braid help cables follow tight bends behind the motherboard tray without adding bulk.

Questions about this item

Does my power supply need standard ATX 24-pin, PCI-E 8-pin and EPS 8-pin outputs for this kit to work?

Yes, the extensions plug into a standard ATX 24-pin motherboard connector, three PCI-E 8[6+2]-pin GPU connectors and two EPS 8[4+4]-pin CPU connectors on your existing PSU.

Will the 300 mm length reach cleanly in a full-tower case with the PSU mounted at the bottom?

At 300 mm each cable adds 30 cm from the PSU socket, which is long enough for typical bottom-mount full-tower routing while leaving slack for the included comb board.

How can I confirm every pin is seated correctly after I route the cables behind the motherboard tray?

Verify the 24-pin, both 8-pin EPS and all three 8-pin PCI-E connectors click fully into their headers, then power on and check that the motherboard, CPU and GPU all initialise without POST errors.
