Kit contents and target builder

This FormulaMod Fm-NCK1 kit supplies a sleeved 24-pin ATX extension, three 8-pin PCIe GPU extensions and two 8-pin EPS CPU extensions, each 300 mm long with white forward-bending connectors. It is aimed at PC builders who want a clean, colour-coordinated cable run without replacing the power supply's own modular loom.

Build integration and clearance

The male 5557 to female 5559 interface lets the extensions plug directly onto any standard ATX PSU cables, so no custom pin-out is required. Forward-bending ends reduce the depth needed behind the motherboard tray, while the included polypropylene comb board lets you cut and arrange combs to keep every wire aligned.

Sustained-load construction

Each lead uses 18 AWG cores wrapped in an insulated middle layer and a soft nylon outer braid, a three-layer structure designed to resist heat during continuous operation. The 3 mm overall diameter stays flexible for routing yet maintains its shape under the steady current draw of high-end graphics cards and multi-core processors.

Questions about this item

How much extra length does the 300mm extension add to my ATX 24Pin cable?

Each cable in the kit measures 300mm end to end, so the ATX 24Pin extension adds exactly that much reach between your PSU and motherboard connector.

Will the 18AWG wires and nylon braid handle continuous load without overheating?

The 18AWG conductors are wrapped in an insulated middle layer for heat resistance and a soft nylon outer braid, a construction designed to run safely under sustained power delivery.

My PSU has fixed cables — will the Male 5557 to Female 5559 connectors fit directly?

Yes, the extensions plug in-line between your existing PSU cables and the component headers, so no modular PSU or extra adapters are required.
