  • Converts standard 24-pin ATX PSU to 18-pin HP motherboard connector
  • Enables PSU replacement on HP Z420 and Z620 workstations

  • Compact 30 cm length fits tight workstation chassis
  • Single 24-pin to 18-pin adapter cable included

Targeted Compatibility

This adapter cable converts a standard 24-pin ATX power supply connector to the proprietary 18-pin format required by HP Z420 and Z620 workstation motherboards. It is intended for system builders or upgraders replacing the original power supply in these specific HP platforms. It does not support the HP Z210 model.

Power Delivery Specifications

The cable uses 18AWG conductors rated for a maximum power throughput of 1000 watts. At approximately 30 cm in length, it is designed for internal routing within the chassis without excess slack. Thermals, noise and power draw depend entirely on the connected power supply and system load rather than the adapter itself.

Package Contents

The retail package includes a single ATX 24-pin to 18-pin adapter cable. No additional mounting hardware, cable ties or software utilities are bundled. The accessory simply enables the physical and electrical connection between a standard ATX PSU and the compatible HP motherboard.

Questions about this item

How do I connect the 24-pin ATX side to the 18-pin HP motherboard without forcing the keying?

Align the 24-pin plug with the power supply and the 18-pin plug with the motherboard; the 30 cm cable reaches without strain and the 18AWG wires handle up to 1000 watts.

Will the 18AWG wires or connectors degrade if I run the system at high load daily?

The 18AWG conductors are rated for the full 1000 watt maximum, so normal sustained use does not require scheduled replacement of the cable.

At what point does the 1000 watt rating become the limiting factor during continuous operation?

The adapter is specified for a maximum of 1000 watts; sustained draws above that will exceed the cable's rated capacity first.
