Two black 24-inch CPU 4-pin power extension cables with locking connectors

SMUGDESK

SMUGDESK ATX CPU 4 Pin Extension Cable 24 inch 2 Pack

SKU CH-WKHG-RA2A8

Two 24-inch ATX CPU 4-pin extension cables extend the 12V motherboard power connection for tidy routing in full-size cases

  • Extends CPU power reach by 24 inches for tidy cable routing
  • Two cables included to support multi-device builds or backup needs
  • Tinned copper conductors maintain stable 12V delivery under CPU load
  • Locking connectors prevent accidental disconnection during long-term operation
  • Compatible with standard ATX power supplies and 4-pin motherboard headers

ATX CPU 4 Pin Extension Cable

This ATX CPU 4 Pin extension cable extends the motherboard 12V power connection from the power supply. It uses a female-to-male design to bridge the gap when the stock CPU power lead is too short. The 24-inch length suits full-size and mid-tower chassis for tidy cable routing. A pack of two cables supports multi-device builds or provides a spare.

Practical limits of the 4 pin standard

The cable is only for CPU 4 pin power and cannot be used for PCIe graphics power or 8 pin CPU ports. Locking molded connectors prevent accidental disconnection during long-term operation. Tinned copper conductors deliver stable 12V power with lower energy loss. Universal compatibility covers mainstream ATX power supplies and desktop motherboards with a CPU 4 pin interface.

Capacity and headroom

Two cables in the pack give enough reach for most dual-connection needs or a backup. The 24-inch length comfortably handles large case layouts and complex routing paths. It runs out when the build requires an 8 pin CPU connector or GPU power, which this cable does not support. Builders needing longer runs or different pin counts must choose a different product.

Questions about this item

One 24-inch cable or the 2-pack — which fits my build?

Choose the 2-pack if you need to extend CPU power on two motherboards or want a spare for future builds; a single cable is enough for one standard ATX CPU 4-pin connection.

Will the 12V delivery stay stable under heavy CPU load?

High-purity tinned copper conductors and secure locking connectors keep 12V power steady, preventing voltage drops that can cause instability when the processor draws maximum current.

Does the 4-pin ATX connector limit the power my CPU can draw?

The cable simply extends the existing 4-pin 12V line from a standard ATX PSU, so the practical limit remains whatever your power supply and motherboard header are rated to provide.
