SMUGDESK 4Pin ATX CPU Power Extension Cable 20cm

SKU CH-WE7A-RC1C3

Extends a desktop CPU 12 V power cable by 20 cm using UL-listed 18 AWG tinned copper wire and locking 4-pin connectors

  • Universally compatible 4-pin ATX design fits Intel, AMD and major PSU brands
  • UL-listed 18AWG tinned copper conductors deliver stable current with low voltage drop
  • 20cm length simplifies cable routing and improves case airflow
  • Locking latch connectors prevent accidental disconnection during operation
  • High-temperature resistant sheath resists aging for long-term high-load reliability

4Pin ATX CPU Power Extension Cable 20cm

This 20cm extension cable uses a standard 4Pin male-to-female connector to lengthen the CPU 12V power lead from an ATX power supply. It is built for desktop builders and upgraders who find the factory cable too short for clean routing inside their chassis. The cord works with mainstream Intel and AMD motherboards and major power-supply brands without adapters. Plug-and-play installation suits both new builds and maintenance tasks.

UL 18AWG tinned copper wire for sustained load

Conductors are UL certified 18AWG tinned copper, chosen for stable current delivery and low resistance under continuous high-load operation. The specification reduces voltage drop so the CPU receives consistent power during extended workloads. High-temperature resistant insulation resists ageing and wear during long periods inside a warm case. Locking latches on both connectors prevent accidental disconnection caused by vibration or thermal cycling.

20cm length aids cable management and airflow

The optimised 20cm reach lets builders route the CPU power cable neatly behind the motherboard tray or along designated channels. Shorter excess length lowers airflow resistance and helps chassis heat dissipation compared to coiled stock cables. Secure locking buckles keep each interface firm during transport or case movement. The cord is intended solely for the CPU 4Pin power port and does not serve PCIe or other 12V connectors.

Questions about this item

Will the 18AWG tinned copper wire run hot when the CPU draws full load all day?

The UL listed 18AWG tinned copper conductors are rated for stable current delivery with low resistance, and the high temperature resistant insulation sheath is designed for long term high load operation inside the case.

Does my power supply need a specific 4 pin P4 12V output to use this extension?

Yes, the cable plugs into a standard ATX 12V P4 4 pin male connector on the PSU side, so the power supply must provide that exact 4 pin CPU power output.

Can I keep my existing motherboard and just add this 20cm extension to reach the CPU socket?

The extension follows the ATX 12V P4 specification and fits mainstream Intel and AMD motherboards, so it will work with your current board as long as it uses a 4 pin CPU power socket.
