240W SFF power adapter

This 240 watt replacement adapter is built for Dell Optiplex small form factor desktops including the 390, 790, 990, 3010, 7010 and 9010. It matches the H240AS-00, AC240AS-00, L240AS-00 and related part numbers listed by the manufacturer. Buyers who need a unit for tower or micro-tower chassis cannot use this adapter.

Sustained 240W delivery

The unit is rated to supply 240 watts continuously rather than only in short bursts, keeping voltage stable during long work sessions or background tasks. Component selection targets steady output without thermal throttling under the load profiles typical of these SFF systems. Systems that demand more than 240 watts will require a different power solution.

SFF form-factor fit

The single specification that decides compatibility is the small form factor chassis requirement; this adapter only fits the SFF versions of the listed Optiplex models. Installing it in a full-size or micro-tower case is not supported by the mechanical design. Verify the chassis type before ordering.
