SMUGDESK 20cm 4Pin ATX CPU Power Extension Cable 18AWG

SKU CH-38XC-T6TP3

Extends the CPU power connection by 20cm using UL certified 18AWG wire for stable current delivery and tidy cable routing

  • Extends CPU power reach by 20cm for flexible motherboard placement
  • UL certified 18AWG wire minimises voltage drop under heavy CPU load
  • Secure moulded connectors resist loosening from chassis vibration
  • Flexible cable body enables clean routing inside compact cases
  • Plug-and-play design simplifies DIY builds and hardware upgrades

4Pin ATX CPU Power Extension

This 20cm cable extends the 4Pin ATX CPU power connection between a power supply and motherboard. It uses UL certified 18AWG wire to maintain stable current delivery with minimal voltage drop. The moulded male-to-female connectors resist loosening from chassis vibration. Designed for internal desktop PC assembly and cable management.

DIY builders needing extra CPU cable reach

Suitable for custom gaming PCs, compact chassis modifications and hardware upgrades where the stock CPU power cable falls short. The 20cm length helps tidy routing without excess slack. Not for users needing longer runs or those with 8Pin EPS motherboard connectors. Cannot replace 4Pin IDE power cables or serve GPU power needs.

18AWG wire capacity and 20cm routing headroom

The 18AWG conductors handle typical desktop CPU loads without significant voltage loss under load. Flexible jacket eases routing behind motherboard trays and through tight grommets. Secure connectors prevent intermittent contact during transport or vibration. Length suits most mid-tower builds; larger cases or rear-routed PSUs may require a longer extension.

Questions about this item

Does my power supply need a 4-pin ATX CPU connector for this cable to work?

Yes, the cable plugs into a standard 4-pin ATX CPU power socket on the PSU and extends it to the motherboard.

Will this extension reach across a full-size ATX motherboard tray?

The cable is 20cm long, which is intended for tidy routing inside compact or standard cases rather than spanning a full ATX board.

How can I confirm the cable is delivering stable power after installation?

The system should POST and run without unexpected shutdowns or CPU throttling under load, indicating low voltage drop through the 18AWG wire.
