Extension Cable for ATX 24-Pin Power

This 12 inch extension lengthens the connection between a power supply and the motherboard 24 pin socket. It suits builders whose PSU cable falls short or needs rerouting around a CPU cooler. The braided sleeve resists tangles and keeps the interior tidy. Both ends carry standard 24 pin ATX connectors.

Male to Female 24 Pin with 18 AWG Wire

The cable uses 18 AWG conductors rated for 270 W maximum power delivery. Male connector plugs into the PSU cable while the female end accepts the motherboard header. Latches on both ends secure the connection against accidental disconnection. No other wire gauge or current rating applies to this part.

Simple Install with Latch Checks

Push each connector until the clip clicks to ensure full seating. The short 12 inch length limits routing options in large cases or behind motherboard trays. Removable cable ties help dress the sleeve but cannot compensate for insufficient reach. Verify clearance before closing the side panel.

Questions about this item

How much extra reach does the 12 in extension add to my PSU cable?

The 12 in length lets you route the 24 pin ATX power cable around a CPU cooler or behind the motherboard tray without stretching the original PSU lead.

What does the 18 AWG wire gauge and 270W rating mean for my build?

18 AWG conductors are rated for 270W, covering typical ATX 24 pin motherboard power draw from mainstream CPUs and GPUs.

Will the braided sleeve and latch connectors fit a standard 24 pin motherboard header?

Yes, the male end plugs into the PSU cable and the female end clips onto the standard 24 pin motherboard connector with latches on both sides.
