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

SKU CH-JK3S-XJWZP

Connects a standard ATX PSU to Z420 or Z620 workstation motherboards using 18AWG copper conductors for stable power delivery

  • Connects standard ATX PSU to Z420/Z620 motherboards
  • 18AWG copper wire minimises voltage drop
  • 30 cm length eases internal cable routing
  • Precision-moulded connectors prevent accidental power loss
  • Enables aftermarket PSU upgrade on proprietary workstations

Purpose and Compatibility

This 30cm adapter connects a standard ATX 24pin power supply to the proprietary 18pin main power connector found on Z420 and Z620 workstation motherboards. It enables the use of a regular retail ATX PSU when replacing the original proprietary unit. The cable is built specifically for this conversion and is not compatible with other motherboard platforms. Buyers who need to adapt a different workstation connector or a standard consumer board cannot use this cable.

Critical Specification

The cable uses 18AWG copper conductors to carry sufficient current and minimise voltage drop under high load. This wire gauge is the single specification that determines whether the adapter can reliably deliver stable power to the motherboard. Precision moulded connectors on both ends ensure a tight, secure fit with the 24pin ATX PSU port and the 18pin mainboard socket, preventing loose connections and accidental power loss. A different gauge would not meet the current requirements of this workstation application.

Build Quality and Routing

The flexible, durable outer jacket resists wear and allows neat cable management inside the workstation chassis. This makes routing easier during a PSU upgrade or repair project, keeping airflow paths clear and reducing strain on the connectors. The 30cm length is tailored for internal workstation layouts, providing enough reach without excess slack. No additional accessories or software are included; the cable itself is the complete solution for the power conversion task.

Questions about this item

What does the 24Pin to 18Pin conversion actually do for my workstation?

It lets you plug a standard ATX power supply into the proprietary 18Pin main power socket on Z420 or Z620 motherboards, so the board receives the correct pinout and voltage rails from a regular PSU.

Which ATX standard does the 24Pin side follow, and does it limit power delivery?

The 24Pin male connector follows the standard ATX 2.0 pinout; the 18AWG copper conductors are rated for the full current the motherboard draws through its 18Pin socket, so no artificial cap is introduced.

What clearance or mounting space does the 30cm cable need inside the case?

The 30cm length and flexible jacket let you route the adapter behind the motherboard tray or along the PSU shroud; both connectors are standard height, so no extra bracket or standoff is required.
