Short multicoloured 18AWG adapter cable with 4-pin female to 8-pin male connectors

Vszerda

Vszerda ATX P4 4-Pin to EPS 8-Pin Internal Power Cable 6 inch 18AWG

SKU CH-MX9S-4WP31

Converts a PSU 4-pin P4 12 V connector to an 8-pin EPS 12 V motherboard socket using 18 AWG UL1007 wire in a 6 inch length

  • Converts 4-pin CPU power to 8-pin EPS for newer motherboards
  • 18AWG tinned copper wire rated UL1007 handles 12V DC reliably
  • Short 6-inch length keeps cable routing tidy inside the case
  • Female P4 connector plugs directly into existing PSU 4-pin header
  • Male 8-pin EPS end fits modern CPU power sockets securely

Adapter Purpose

This 6-inch adapter converts a power supply's 4-pin P4 12V connector into an 8-pin EPS 12V plug so newer motherboards can be powered from older PSUs. It targets builders upgrading a motherboard while retaining an existing power supply that lacks a native 8-pin CPU header.

Cable Construction

The cable uses 18AWG tinned copper conductors rated to UL1007 with a multi-colour insulation scheme. The UL-listed wire gauge supports the 12V DC delivery required by the EPS specification without adding bulk inside the chassis.

Daily Fit

At six inches the adapter reaches from a typical PSU cable grommet to the CPU socket area without excess slack that would impede airflow. The female 4-pin and male 8-pin ends lock securely, so the connection stays seated during transport or vibration.

Questions about this item

Will the 18AWG tinned-copper wires need replacement after extended use?

The 18AWG UL1007 tinned-copper conductors are rated for continuous 12 V DC delivery and do not have a scheduled replacement interval.

What limits the adapter when the CPU draws sustained power through the 4-pin to 8-pin conversion?

The 4-pin P4 female connector is the limiting factor; it can carry less current than the 8-pin EPS male side, so total power is capped by the source header.

Does the 6-inch 18AWG cable add noticeable heat or resistance during all-day operation?

The short 6-inch length and 18AWG UL1007 wire keep voltage drop and heat rise minimal under normal 12 V DC loads.
