Questions about this item

What is the maximum continuous power the 210 W unit can deliver to an OptiPlex GX280?

The supply is rated at 210 W, so sustained draw should stay at or below that figure to avoid triggering protection.

How loud is the fan and how much heat does the 210 W unit produce under full load?

The internal fan spins only as fast as needed; at full load the unit exhausts roughly 210 W of heat, so case airflow must handle that thermal output.
