HP ProLiant DL320 G4 - Configuring Power Supply


The DL320 G4 supports 450 W PFC (Power Factor Correcting) power supply, which is different from and cannot be swapped out with the previous generation. The form factor and the removal and replacement procedure are similar.

There is only one screw that secures the power supply internally and two screws that secure it to the rear of the chassis for a total of (3) screws.

NOTE: Do not open the power supply module. It is a single spared unit with no serviceable parts inside.
