ATX 20-pin to EPS 24-pin adapter

This adapter converts a standard 20-pin ATX power supply for use with a motherboard requiring a 24-pin ATX connector. It features an 18AWG tinned copper cable measuring 6 inches with a 20-pin female connector on one end and a 24-pin male connector on the other. The unit supports 3.3, 5 and 12V DC delivery.

Sustained load behaviour

The 18AWG tinned copper conductors handle continuous current at the rated voltages without the voltage drop seen in thinner wires. A short 6-inch run minimises resistance so the adapter remains stable during extended operation. It simply passes through the power supply's own regulation and protection.

ATX 24-pin interface limits

The 24-pin connector adds four pins carrying extra 3.3, 5 and 12V lines plus ground compared to the 20-pin version. This adapter supplies those pins from the existing 20-pin source, so total current cannot exceed what the original supply provides. It does not create additional power capacity.

Questions about this item

Will the 18AWG wires run hot or draw extra power when the adapter stays connected all day?

The 18AWG tinned copper conductors are rated for the 3.3, 5 and 12 V DC lines the ATX connector carries, so normal continuous use adds no measurable heat or power loss.

My power supply only has a 20-pin ATX plug — is that the only thing I need to use this adapter?

Yes, the adapter mates a 20-pin female ATX PSU connector to a 24-pin male motherboard socket; no extra cables or converters are required.

I'm keeping an older 20-pin PSU — will the 6-inch adapter reach the 24-pin socket on a modern board without strain?

At 6 inches long the cable bridges the gap between a standard ATX PSU and a 24-pin motherboard header, leaving enough slack for tidy routing in most chassis.
