Dual PSU Extension Cable

This cable lets a single motherboard start and control two ATX power supplies simultaneously. It connects the 24‑pin motherboard header to both PSUs using 18AWG wire with 5557 and 5559 connectors. The 30 cm length suits compact dual‑PSU builds. Builders running multiple graphics cards or high‑current mining rigs gain a tidy way to share the power‑on signal.

Upgrade From Single PSU Wiring

It replaces the common workaround of shorting the green wire on a second PSU, which leaves that unit running independently of the motherboard. With this cable both supplies power up and down together when the case button is pressed. The jump is worth it when a build draws more current than one PSU can deliver cleanly, or when separating GPU power from system power improves stability.

Sustained Load Behaviour

The 18AWG conductors rated to the 1007 specification carry continuous current to the second PSU without significant voltage drop across the 30 cm run. PVC insulation and a 2.1 mm outer diameter resist heat buildup during extended mining or compute sessions. Both PSUs remain synchronised through the motherboard signal, so the secondary unit does not stay live after a shutdown.

Questions about this item

What connector types are on each end of the 30 cm dual PSU extension cable?

One end has a 5557 24pin (20+4) connector and the other end has a 5559 24pin connector.

How do I connect the two PSUs so they start together?

Plug the 5557 end into the motherboard 24pin socket, connect the 5559 end to the second PSU 24pin socket, and both units will power on from the case button.

When should I replace this 18AWG dual PSU cable?

Replace it if the PVC insulation cracks, the 34×0.12TS conductors are exposed, or the 5557/5559 pins become loose or bent.
