Power cable Supermicro CBL-PWEX-1034Z-30 2×ATX 1×4 P4.2 to 2×MicroHi 4+2 30cm 16AWG

The Supermicro power cable CBL-PWEX-1034Z-30 adapts a single 4-pin P4.2/ATX power input into two MicroHi 4+2 outputs. Built with 16 AWG conductors and a 30 cm jacketed length, this internal cable is intended for server and workstation power distribution where two MicroHi connectors are needed from one ATX-style feed. The cable is suitable for direct connection to compatible power supply units and internal components in Supermicro and similar systems.

Advantages

This cable provides a compact, single-cable solution to split one 4-pin ATX/P4.2 power source into two MicroHi 4+2 connectors without requiring additional adapters. The 16 AWG wiring supports reliable current delivery for typical server peripheral needs, while the 30 cm length offers a balance between reach and cable management inside chassis. The molded connectors ensure secure mating and reduce the risk of loose connections in dense internal layouts.

Suitable for

• Internal server or workstation builds requiring two MicroHi 4+2 power connectors from one ATX/P4.2 feed
• Replacing or extending existing PSU-to-component power connections in Supermicro systems
• Dense rackmount or compact chassis where short, split power runs are needed

When it may not be suitable

This cable is not intended for use as an external power lead or for applications that require mains voltage connections. It is designed for internal DC power distribution and may not meet requirements for devices that need higher gauge conductors or longer cable runs. If components require individual dedicated power feeds with higher current capacity, a different wiring solution may be preferable.

Key specifications

• Connector configuration: 1 × 4-pin ATX/P4.2 input to 2 × MicroHi 4+2 outputs
• Cable length: 30 cm
• Conductor size: 16 AWG
• Application: internal server/workstation power distribution
• Number of outputs: two MicroHi 4+2 connectors

How to use

Install the cable by connecting the 4-pin P4.2/ATX end to the appropriate power output on the power supply unit, ensuring correct orientation and secure seating. Route the cable inside the chassis to avoid obstructing airflow and to maintain tidy cable management. Plug each MicroHi 4+2 connector into the target internal components, confirming that pin alignment and latch engagement are correct before powering the system. Verify connections during initial power-up and monitor for any signs of loose contact or overheating.

What to consider before purchase

• Ensure the target devices accept MicroHi 4+2 connectors and that the single ATX/P4.2 source provides sufficient current for both outputs
• Confirm 30 cm length is adequate for routing inside your chassis
• Verify that 16 AWG conductor size meets the current requirements of connected components

Usage recommendations

For reliable operation, use this cable only within compatible internal systems and avoid bending the cable sharply near connector ends. Keep cable runs clear of hot components and secure with cable ties as needed to prevent strain on connector housings.
