COMeap PCIe-to-CPU Power Adapter

This 13.3-inch cable converts a PCIe 8-pin female connector from a power supply into a detachable CPU 8-pin (4+4) EPS-12V male connector for the motherboard. The split design allows the 4+4 section to be used as either an 8-pin EPS or a 4-pin ATX plug. It targets builders adapting an existing PSU for dual-CPU or server boards that require EPS-12V power.

Thermals and Power Delivery

The adapter uses 1007-18AWG tin-coated copper wire rated for the current carried by standard EPS-12V connections. Because it is a passive cable with no active components, it adds no measurable heat or noise to the system. Power draw is determined entirely by the connected motherboard and CPU; the adapter simply passes the supply voltage through.

Build and Daily Use

A black sleeved jacket protects the conductors and resists abrasion during routing. The package includes a self-adhesive tape strip for securing the cable inside the chassis. The connector is keyed for motherboard EPS/ATX sockets only; the supplier warns that plugging it into a graphics card will cause damage. Builders needing GPU power or a longer reach must seek a different cable.

Questions about this item

How do I install the PCIe 8-pin to CPU 8-pin (4+4) adapter and what is the common mistake?

Connect the PCIe 8-pin female end to the power supply's PCIe port, then attach the detachable 4+4 male end to the motherboard EPS socket; the error is plugging it into a GPU instead of the motherboard.

What maintenance or replacement will this 18 AWG sleeved adapter need over time?

Inspect the 1007-18AWG tin-coated copper wires and sleeving for cracking or heat discolouration; replace the cable if connectors become loose or insulation degrades.

What limit appears first when the adapter runs continuously at high load?

The 18 AWG conductor rating and 13.3-inch length set the current-carrying and voltage-drop ceiling before the motherboard's EPS-12V demand exceeds safe levels.
