SMUGDESK

SMUGDESK ATX 24Pin to 18Pin PSU Adapter Cable 30cm for HP Z620 Z420

SKU CH-AZKP-S6ZJ2

Connects a standard ATX power supply to the proprietary 18-pin motherboard connector on HP Z420 and Z620 workstations

  • Standard PSU upgrade for Z620/Z420 via 24pin-to-18pin adapter
  • 30cm passive cable fits workstation chassis for tidy routing
  • 18AWG copper wires deliver stable power under full load
  • Factory-mapped pinout prevents boot failure and hardware damage
  • Enables aftermarket ATX supply replacement on proprietary mainboards

Target Workstations

This adapter cable connects a standard 24 pin ATX power supply to the proprietary 18 pin motherboard connector found on HP Z620 and Z420 workstations. It is built for system integrators and repair technicians who need to replace a failed or unavailable OEM power unit with an aftermarket ATX unit. The 30 centimeter length provides enough slack for internal routing.

Who Should Look Elsewhere

The pinout is mapped exclusively for Z620 and Z420 mainboards, so the cable will not work with standard ATX motherboards or other workstation generations. Buyers who need to adapt power for a different proprietary connector or a regular desktop board must choose a different adapter. Professional installation is highly recommended to avoid damage from incorrect wiring.

Deciding Specification

The critical specification is the factory mapped 18 pin pinout that matches the HP Z620 and Z420 motherboard power socket exactly. Without this precise pin definition the motherboard will not boot or may suffer permanent damage, making the pinout the single detail that determines whether this is the correct part.

Questions about this item

Does the 30 cm adapter cable generate any heat or noise when the workstation runs continuously?

The cable is a passive 18 AWG copper link with no active components, so it produces no noise and negligible heat during all-day operation.

What existing power supply must I already have for this adapter to work with my Z620 or Z420?

You need a standard ATX power supply with a 24-pin main connector; the adapter converts that output to the proprietary 18-pin motherboard socket.

Will this adapter let me keep my original HP power supply while adding a newer ATX unit?

No, the adapter replaces the OEM supply entirely — it connects one aftermarket ATX 24-pin PSU to the Z620 or Z420 motherboard and is not designed for dual-supply configurations.
