What to Check Before Buying

1. Confirm the Workstation Model

Make sure you have an HP ProDesk 400 G5 Micro Tower (MT).

2. Check the Original Wattage

The ProDesk 400 G5 MT standard configuration is 180W. If you plan to add power-hungry components (like a dedicated graphics card), consider whether a higher wattage upgrade is possible.

Note the model, spare number, and other identification information printed on the existing unit.

4. Verify Physical Dimensions

The PSU must fit correctly inside your MT chassis. The ProDesk 400 G5 MT has specific space constraints that differ from SFF models.

5. Compare Connectors

Ensure the replacement provides the appropriate motherboard connections. The PWRCMD 7-pin connector is standard on this model .
