Black 6-inch adapter cable with 4-pin female to 8-pin male connectors, 18AWG copper wires

Vszerda 4 Pin to EPS 8 Pin Power Adapter Cable 6 inches

SKU CH-3JXD-6B86P

Converts a 12V 4-pin PSU connector to an 8-pin EPS motherboard socket using 18AWG copper conductors in a 6-inch cable

  • Converts a 4-pin PSU connector to an 8-pin motherboard CPU socket
  • 18AWG copper conductors deliver reliable 12 V power to the CPU
  • Short 6-inch length keeps cable routing tidy inside the case
  • Female ATX 12 V P4 plugs directly into the power supply
  • Male ATX 12 V EPS connector mates securely with the motherboard

Purpose and compatibility

This adapter cable converts a power supply's 12V 4-pin ATX connector into an 8-pin EPS motherboard CPU power connector. It is intended for builders using a PSU that only provides a 4-pin P4 auxiliary plug with a motherboard requiring an 8-pin EPS socket. The cable cannot be used for graphics cards; connecting it to an 8-pin video card power input will cause damage.

Thermals noise and power

The cable uses 18AWG copper conductors to carry 12V power between the PSU and motherboard. As a passive wiring assembly it generates no noise and adds negligible thermal load to the system. Power delivery is limited by the source 4-pin connector and the 18AWG wire gauge.

Sustained load behaviour

Under continuous CPU load the adapter simply passes whatever current the 4-pin PSU connector supplies through the 18AWG wires to the 8-pin motherboard header. No active components alter voltage or current, so behaviour mirrors the PSU's own 12V rail stability. The 6-inch length keeps voltage drop minimal for typical desktop layouts.

Questions about this item

How do I connect the 4-pin P4 plug from my PSU to the 8-pin EPS socket on the motherboard using this 6-inch adapter?

Plug the PSU's 4-pin female P4 connector into the adapter's matching female end, then insert the adapter's 8-pin male EPS connector into the motherboard CPU power socket; the 18AWG copper conductors carry 12 V on both sides.

What upkeep will the 18AWG copper conductors and connectors need over time?

No scheduled maintenance is required; periodically check that both the 4-pin and 8-pin connectors remain fully seated and free of dust or corrosion.

What is the first limitation I will hit when the CPU draws sustained power through this 6-inch adapter?

The 4-pin P4 source is rated for 12 V delivery, so the adapter cannot supply more current than the PSU's 4-pin rail provides, which becomes the limiting factor under heavy load.
