  • Male 24-pin connector fits modern motherboard socket

ATX 20-pin to 24-pin power adapter

This 6-inch cable converts a standard 20-pin ATX power supply for use with a motherboard requiring a 24-pin ATX connector. It features 18AWG tinned copper conductors rated for 3.3, 5, and 12V DC operation. The adapter eliminates the need to replace a working 20-pin PSU when upgrading to a newer motherboard.

Verify PSU and motherboard connector types

Confirm your power supply provides a 20-pin ATX output and your motherboard requires a 24-pin ATX input before ordering. The cable connects a 20-pin female plug to a 24-pin male plug in a fixed orientation. Ensure the 6-inch length allows proper routing between your PSU location and the motherboard socket inside the case.

Stable power delivery under continuous load

The 18AWG copper wires maintain consistent conductivity for the 3.3, 5, and 12V rails during sustained system operation. Short cable length minimises resistance and voltage drop across the adapter interface. Secure connector retention prevents intermittent contact that could cause instability during extended high-draw scenarios.

Questions about this item

Does the cable come with any extra connectors or do I need to buy anything else to use it?

The package contains only the 6-inch 20-pin female to 24-pin male adapter cable. No additional connectors or tools are required; it plugs directly between your existing 20-pin PSU and a 24-pin motherboard socket.

Is the 18AWG gauge suitable for a standard desktop build or should I look for a thicker wire?

The 18AWG tinned copper conductors are rated for the 3.3, 5 and 12V DC lines carried by an ATX power supply, making this gauge appropriate for typical desktop power delivery through the 24-pin connector.

Will the 6-inch length reach from a bottom-mounted PSU to a 24-pin socket near the top of a full-size ATX board?

At 6 inches the cable is designed for tight, direct connections such as test benches or compact cases; it will not span the distance between a bottom-mounted PSU and a top-edge 24-pin header on a full-size ATX motherboard.
