Kit contents and compatibility

The FormulaMod Fm-NCK1 kit supplies a 300 mm ATX 24-pin extension, three PCI-E 8-pin GPU extensions and two EPS 8-pin CPU extensions. All connectors use male 5557 to female 5559 interfaces for direct connection to existing modular cables. The set targets builders who want uniform cable routing without custom-length assemblies.

Capacity and headroom

Each extension uses 18 AWG conductors wrapped in a three-layer structure: insulated core, heat-resistant middle layer and soft nylon braid. The 3 mm diameter cables handle standard ATX, EPS and PCI-E power delivery for current high-end graphics cards and dual-CPU motherboards. Backward compatibility allows 8-pin plugs to serve 6-pin or 4-pin ports with unused pins tucked away.

Build integration

Straight-type connectors and the included polypropylene comb board let you align and secure every cable run inside the case. Ten colour options match motherboard, GPU, RAM or fan lighting themes. The kit replaces stock modular cables entirely, so no additional adapters or soldering are required for a clean, organised interior.

Questions about this item

Will the 300 mm 18 AWG extensions reach from my existing ATX supply to a full-tower motherboard tray?

Each cord measures 300 mm end-to-end, so measure your current cable run; the extra length works for most mid-tower builds but may fall short in very large cases.

How can I verify the male 5557 and female 5559 connectors are seated correctly after routing?

Push each plug until the latch clicks, then tug gently — no movement means the pins are fully engaged; the black connectors on both ends make the latch visible for a quick visual check.

The kit lists one 24-pin, three 8[6+2]-pin and two 8[4+4]-pin cables plus a comb board — are any extra combs or tools needed?

The polypropylene comb board supplies multiple comb sizes you snap out and slide on; no additional combs or tools are required for a clean install.
