Cable Matters 104036x2 2-Pack ATX 4-Pin CPU Extension Cable 8 Inches

What it is and who needs it

The Cable Matters 104036x2 pack contains two ATX 12V P4 4-pin male-to-female extension cables. Each cable measures 20cm (8in) and uses 18 AWG wire rated for up to 80W. The set is built for PC builders who need to bridge the gap between a power supply and a motherboard CPU socket when the stock cable falls short, especially in bottom-mount chassis layouts.

Practical limits of the ATX 4-pin interface

The 4-pin ATX 12V connector delivers auxiliary CPU power up to the cable's 80W rating. It fits older or entry-level motherboards that use a single 4-pin socket rather than the 8-pin EPS variant. The male and female ends both carry latches to prevent accidental disconnection, but the cable cannot supply power to an 8-pin EPS header or support processors that demand more than the connector's rated capacity.

Deciding specification: connector gender and length

The male-to-female gender arrangement extends an existing PSU lead without replacing it, while the fixed 8-inch length determines reach inside the case. Buyers whose motherboard uses an 8-pin EPS socket or whose PSU cable already reaches the CPU header will not benefit from this part.
