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.

Questions about this item

Does the 18 AWG cable core generate noticeable heat when the system runs all day?

The 18 AWG conductors are sized for standard PSU loads, so heat stays minimal during continuous operation.

Which existing PSU connectors are required for the Male 5557 to Female 5559 interface to work?

Your power supply must provide a standard 24-pin ATX, an 8-pin EPS and two 8-pin PCIe sockets.

Will the 300 mm extensions reach cleanly in a chassis built for shorter stock cables?

At 300 mm each, the extensions add length for tidy routing in larger cases without excess slack in compact builds.
