CPU power adapter cable Akasa 8-pin to dual 4+4-pin (AK-CBPW35-20)

Adapter cable Akasa 8-pin to dual 4+4-pin (AK-CBPW35-20) converts a single 8-pin EPS/CPU power lead into two separate 4+4-pin CPU/VRM connectors. The cable preserves the original power path while allowing one 8-pin output from a power supply to feed either one or two CPU power headers that require 4+4-pin plugs. It is designed to simplify cable routing and provide compatibility with motherboards that use split 4+4 connectors without cutting or modifying PSU cables.

Advantages

This Akasa adapter provides a straightforward and reversible way to split an 8-pin CPU power into two 4+4-pin connectors, maintaining correct pin alignment for EPS rails. Its compact inline design reduces clutter inside the PC case and helps with tidy cable management. No soldering or adapter assembly is required, and the cable maintains the PSU's native connector interface, allowing easy installation and removal.

Suitable for

• Motherboards requiring one or two 4+4-pin CPU/VRM power connectors
• Systems where the PSU has only a single 8-pin EPS/CPU cable but the motherboard has split 4+4 headers
• PC builds where improved cable routing and cleaner internal layout are desired

Key specifications

• Input connector: single 8-pin EPS/CPU-style plug
• Output connectors: two 4+4-pin CPU-style plugs (splitable 4-pin halves)
• Cable type: power adapter cable for CPU supply
• Compatibility: standard ATX/EPS CPU power pinout (designed for common PSU/motherboard layouts)
• Construction: molded plastic housings with multi-conductor power cable

How to use

Power off the system and disconnect the PSU from mains before connecting the adapter. Plug the single 8-pin end into the PSU's EPS/CPU power output. Connect one or both 4+4-pin ends to the motherboard CPU/VRM headers as required, ensuring each 4-pin half is correctly aligned and fully seated. Reconnect the PSU to mains and power on the system. Verify system power stability and that the motherboard registers the CPU power connection.

Recommendations

Use this adapter only with compatible ATX/EPS power supplies and motherboards. Do not use as a permanent replacement for a native multi-rail PSU cable if the system requires dedicated independent power rails for high-current CPU configurations. Ensure connectors are fully seated and avoid forcing mismatched plugs; if the motherboard or PSU documentation indicates specific power distribution requirements, follow those manufacturer guidelines.
