HP Z820 1125W workstation power supply

This 1125W ATX unit is built as a direct replacement for the HP Z820 workstation. It matches the original DPS-1125AB A form factor and carries part numbers 716646-002 and 623196-001. The supply is new and intended for owners restoring or servicing that specific platform.

Sustained-load behaviour

The 1125W rating supports continuous delivery to dual-processor configurations and multiple add-in cards without throttling. Voltage regulation remains stable across the full load range, protecting sensitive workstation components during long render or compute sessions. Thermal design targets the Z820 chassis airflow path, so fan speed ramps gradually rather than spiking under extended load.

Questions about this item

How loud or hot does the 1125W unit get when running continuously in an HP Z820?

The 1125W supply is designed for the Z820 workstation chassis; its internal fan and airflow path match the original thermal profile for sustained loads.

Which cables or connectors must my Z820 already have to install the DPS-1125AB A?

The replacement uses the same proprietary motherboard and drive connectors as the factory 716646-002 and 623196-001 units, so no extra cables are required.
