ATX P4 to EPS 8-Pin Adapter

This 6.1-inch adapter converts a power supply's 4-pin ATX 12V connector into an 8-pin EPS 12V plug for motherboards that require the larger CPU power input. It uses 18AWG UL1007 tinned copper wire rated for 12V DC operation. The short length keeps cable routing tidy inside compact chassis.

Builders with 4-pin PSU and 8-pin motherboard

The cable suits builders whose PSU only provides a 4-pin P4 connector while the motherboard demands an 8-pin EPS header. It does not help systems that already have a native 8-pin lead or need additional PCIe power connectors. Buyers who want more length for full-tower routing should look at something else.

18AWG UL-listed wire and short reach

The bundled 18AWG UL1007 wire meets safety standards for 12V DC power delivery and reduces voltage drop over the short run. Its 6.1-inch span limits slack, which improves airflow in small-form-factor builds. No extra sleeves, combs or software are included.

Questions about this item

What PSU connector must I already have to use this EN-Labs ATX P4 to EPS 8-pin adapter?

Your power supply must provide a 4-pin ATX 12V P4 female connector; the adapter plugs into that header and converts it to an 8-pin EPS 12V male plug for the motherboard.

Will this 18 AWG UL1007 adapter handle the power draw of an older 4-pin PSU rail on a modern 8-pin motherboard socket?

The cable uses 18 AWG tinned copper wire rated for 12 V DC, matching the original P4 rail specification, so it carries the same current the PSU already delivers.

How can I confirm the EN-Labs adapter is seated correctly after installation?

Both connectors are keyed — push the 4-pin female onto the PSU header until it clicks, then seat the 8-pin male into the motherboard EPS socket until its latch engages; the system will POST normally when power is applied.
