Questions about this item

What does the 240 W rating mean when the power supply is installed in an Optiplex 390 790 or 990 SFF?

The 240 W rating is the maximum continuous output the unit can deliver to the motherboard drives and expansion cards inside those small-form-factor Optiplex models.

Which power connector standard does the H240ES-01 AC240ES-01 D240ES-01 use and what does it limit?

The unit uses the proprietary Dell SFF power connector which limits use to compatible Optiplex 390 790 and 990 chassis and prevents installation in standard ATX cases.
