ATX 24Pin to 18Pin & 8Pin to 12Pin Power Adapter Cable, Standard ATX PSU Conversion Cord for HP Z440 Z640 Workstation Motherboard Upgrade

This matched power conversion cable set contains an ATX 24Pin to 18Pin main motherboard power adapter and an 8Pin to 12Pin CPU power adapter, tailor-made for HP Z440 and Z640 workstation motherboards.

HP Z440 and Z640 motherboards adopt proprietary 18Pin main power and 12Pin CPU power interfaces, which cannot directly connect to ordinary standard ATX power supplies. This adapter set perfectly solves the upgrade limitation, enabling you to replace the original factory PSU with universal aftermarket ATX power supplies.

Adopted high-quality 18AWG tinned copper wires, the cable effectively reduces resistance and voltage drop under high load. Strictly reproduced official pin definition ensures safe and stable power transmission during heavy computing, rendering, data processing and long-time workstation running. Reinforced connector terminals prevent loose contact caused by vibration inside the chassis.

Ideal for workstation maintenance, power supply upgrade, DIY modification and hardware testing. Direct plug and play without extra modification. It is widely used for CAD design, video editing, 3D rendering and other high-load scenarios based on HP Z440 / Z640 platforms.

Important Reminders:

1. This cable only fits HP Z440 and Z640 workstations. It is NOT compatible with other HP workstation models such as Z420, Z620.
2. Please select an ATX power supply with sufficient rated power to match your workstation configuration.
3. Double-check all connectors are fully locked before powering on to prevent unstable startup.
4. Wrong pinout adapter may cause permanent damage to motherboard; please confirm your model before purchasing.
