Questions about this item

How does the 525W rating translate to actual power delivery inside a Z440 workstation?

The 525W rating represents the maximum continuous output this supply can deliver to the Z440's components through its native connector, matching the workstation's original power specification.

What interface does the DPS-525AB-3A use and what does it limit in practice?

It uses the proprietary HP Z440 power connector, which limits installation to compatible Z440 workstations and prevents use in standard ATX chassis without an adapter.
