32 cm 24-pin PSU extension cable
This 32 cm cable extends a standard 24-pin ATX power connection between a power supply and a motherboard. It uses 18 AWG tinned-copper conductors with PVC insulation and a 2.1 mm outer diameter. The male end combines a 20-pin and 4-pin section so it also fits older 20-pin mainboards. The female end accepts the PSU's native 24-pin plug.
Sustained-load behaviour
Each conductor is built from 34 strands of 0.12 mm tinned copper rated for 80 °C continuous operation. The 18 AWG gauge keeps voltage drop low across the 32 cm run even when the system draws full load for long periods. PVC sleeving protects the wires from abrasion inside a crowded case without trapping heat.
Deciding specification
The cable uses 5557 24-pin (20+4) on the motherboard side and 5559 24-pin on the PSU side; verify that both connectors match your hardware before purchase. Builders who need a longer reach or a different connector keying will need another solution.

Questions about this item
How much heat does the 18AWG wire generate when the 24-pin cable runs continuously?
The 18AWG tinned-copper conductors are rated for 80 °C and use PVC insulation, so normal PSU loads stay well within the temperature limit.
What connectors must my power supply and motherboard already have for this 32 cm extension to work?
One end needs a standard 24-pin ATX plug (5559) from the PSU, the other accepts a 24-pin (20+4) motherboard header (5557).
Will the 20+4 pin male end fit an older motherboard that only has a 20-pin socket?
Yes, the combined 20+4 pin male connector is designed to plug into legacy 20-pin boards as well as full 24-pin sockets.
