Questions about this item

How can I confirm the H250AD-00 is running correctly once installed in my Optiplex 390?

The system should power on without shutdowns, the fan should spin steadily, and no power-related error codes should appear during boot.

What comes with the 7GC81 H250AD-00 and what extra cables or brackets must I source for an Optiplex 990?

The unit ships as the 250W power supply only; any proprietary Dell power cables or mounting brackets required for the Optiplex 990 must be obtained separately.
