Questions about this item

How much continuous power can the 300 W unit deliver to a 9010 system?

The supply is rated for 300 W total output, so it can sustain that load for the 9010 chassis.

What noise level should I expect when the PSU runs all day in a 790 desktop?

The 250 W-class design uses a single internal fan; typical office ambient keeps it barely audible during extended operation.
