HP Z840 replacement PSU

This 1125W unit is built as a direct replacement for the HP Z840 workstation. It matches the original DPS-1125AB-1 A specification and part numbers 719799-002 and 792340-001. The ATX-type form factor fits the proprietary chassis without modification. Buyers needing a different wattage or a standard ATX pinout for a custom build should look elsewhere.

Installation fits the Z840 bay

Slide the module into the dedicated power-supply bay until the latch engages; no cables need repinning because the connector matches the factory layout. The most common issue is forgetting to seat the unit fully so the locking tab clicks, which leaves the system without power. Verify the part number on the label matches 719799-002 or 792340-001 before installing to avoid a mismatch.

Questions about this item

How can I confirm the 1125W PSU is operating correctly after installing it in my HP Z840?

The system should power on without errors, the PSU fan should spin, and the workstation should remain stable under full load.

What comes with the DPS-1125AB-1 A unit and what must I source separately?

The power supply itself is included; you will need to provide the AC power cord and any HP Z840-specific mounting hardware or cables not already present in the chassis.
