Purpose and Compatibility

This 4-pin to 8-pin CPU power adapter extends an existing 4-pin connector and converts it to an 8-pin (4+4) plug for motherboards that require the larger socket. It is suited for builders reusing older power supplies with modern boards that only offer an 8-pin CPU power header.

Cable Construction and Capacity

The cable uses 18AWG tin-plated copper conductors with a 1.02 mm diameter and 0.81 mm² cross-section, rated for 300 V and 80 °C under the UL 1007 standard. At 8 inches long, it provides enough reach for typical ATX layouts while the double-shielded, PVC-insulated wire and mesh sleeve keep routing tidy and resist corrosion.

Interface Limits

The adapter relies on the original 4-pin source, so total CPU power delivery cannot exceed what that single 12 V rail supplies; boards drawing sustained current beyond the 4-pin specification may become unstable. The safety-lock connectors prevent accidental disconnection, but the 20 cm length offers no slack for full-tower rerouting or rear-cable-management channels.

Questions about this item

Will this 8-inch 18AWG adapter reach the 8-pin CPU socket when my PSU only has a 4-pin connector?

The cable measures 8 inches (20 cm) and converts a 4-pin PSU plug into an 8-pin (4+4) motherboard connector, extending the reach inside the case.

How can I verify the cable is delivering power correctly once installed?

The system will POST and the CPU will receive power through the 18AWG tin-plated copper conductors rated for 300 V and 80 °C.

Does the package include any extra cable ties or mounting brackets?

One adapter cable is supplied; the PVC sheath and mesh sleeve help keep the wiring tidy without additional accessories.
