ATX 4-Pin CPU Extension Cable 2-Pack

This 2-pack of ATX 4-pin CPU extension cables adds 8 inches of reach between a power supply and a motherboard P4 connector. Each cable has a male 4-pin P4 plug on one end and a female 4-pin P4 socket with latches on the other. The cables suit PC builders who need extra length when installing a power supply in a bottom-mount case.

Thermals Noise and Power Draw

The cables are rated for a maximum of 80 watts and use 18 AWG conductors. They are passive wiring with no active components, so they add no fan noise, no heat of their own and no measurable power draw beyond the normal resistive losses of the copper. The tangle-free jacket helps keep airflow paths clear inside the chassis.

Bundled Accessories and Software

The pack supplies two identical extension cables and nothing else. There is no software, no driver, no sleeve kit, no comb, no Velcro tie and no adapter included. The second cable serves as a spare for a future build or a second workstation, giving the builder a ready replacement if a connector latch ever fails.

Questions about this item

How do I install the 8-inch 4-pin ATX extension and what step do people often miss?

Route the male end to the PSU's 4-pin CPU output and the female end to the motherboard's P4 socket, pressing until both latches click; the step often missed is fully seating the latch on the motherboard side to prevent accidental disconnection.

What maintenance or replacement will the 18 AWG cable need over time?

No scheduled maintenance is required; inspect the connectors and 18 AWG wires during any build change and replace the cable if you see cracked insulation, melted plastic or loose latch tabs.

What limit appears first when the cable runs at its 80 W rating continuously?

The 18 AWG conductors reach their thermal limit first; sustained 80 W load will warm the cable, so ensure case airflow keeps the jacket temperature within safe operating range.
