FormulaMod NCK1 Series PSU Extension Cable Kit Mix Color 300mm ATX24Pin PCI-E8Pin CPU8Pin With Combs

Extension cable kit for custom-loop builders

This FormulaMod NCK1 kit supplies three sleeved extensions — one ATX 24-pin, two PCI-E 8-pin and one CPU 8-pin — each 300 mm long with 18 AWG cores and 3 mm outer diameter. Male 5557 to female 5559 connectors plug directly between your power supply and existing cables. Included combs keep every wire aligned inside tubing runs.

Steady current delivery across full-length runs

The 18 AWG copper cores maintain voltage stability when the system draws continuous load from GPU and CPU simultaneously. Heat dissipation stays consistent because the fixed 300 mm length adds no extra resistance beyond what the PSU already expects. Combs prevent individual strands from shifting and creating hot spots during prolonged gaming or render sessions.

Verify connector gender

Your power supply must present female 5559 sockets to accept the male 5557 ends on these extensions. Measure the routing path from PSU to motherboard, GPU and CPU headers to confirm 300 mm reaches without tension. Builds using non-standard pinouts or proprietary PSU cables cannot use this kit.
