Extension cable kit for liquid-cooled builds

The FormulaMod Fm-NCK1 kit supplies pre-assembled cables that connect a power supply to the motherboard and graphics card inside a liquid-cooled chassis. White 18 AWG conductors run 300 mm from male 5557 to female 5559 connectors, and each cable includes two matching combs for alignment. The set covers ATX 24-pin, PCI-E 8-pin and CPU 8-pin paths in a single package.

Thermals noise and power draw in normal use

Because the kit carries only electrical current, it adds no heat, noise or fan load to the cooling loop. The 18 AWG gauge is rated for the current delivered by standard desktop power supplies, so voltage drop across the 300 mm length remains negligible. No active components are present, leaving the thermal and acoustic profile entirely unchanged.

Build fit what it needs and what it frees

The fixed 300 mm length suits compact reservoirs and tight routing channels where stock cables would bunch or kink. Male-to-female 5557-to-5559 interfaces plug directly into existing PSU and component headers without adapters. Pre-fitted combs keep wires parallel, freeing space around water blocks and radiators for cleaner tubing runs.

Questions about this item

How do I plug the 5557 male end into my PSU and the 5559 female end into the component without forcing the pins?

Align the 5557 male connector with the PSU port and the 5559 female connector with the component header, then press straight in until the latch clicks; the 18 AWG cores are stiff, so do not rock the plug sideways or the pins can bend.

Will the white sleeving or the two included combs per cable yellow or loosen over time, and should I plan to replace them?

The sleeving is colour-fast under normal case temperatures and the combs snap tightly onto the 3 mm diameter cables; they do not require scheduled replacement unless you physically break a comb during a rebuild.

At what point does the 300 mm length become the limiting factor when routing behind a large motherboard tray?

The fixed 300 mm reach from PSU to component is the first constraint; if the grommet-to-header distance exceeds that, the cable will pull tight and you cannot extend it without ordering a custom length.
