The Dell H180AS-00 is a 180W small-form-factor power supply built for OptiPlex 3040, 5040 and 7040 SFF desktops. It also supports OptiPlex 3650, 3656 and Inspiron 3250, 3650, 3655, 3656 MT systems. Precision 3420 workstations are listed as compatible.

Swaps a failed or noisy unit

Replaces an existing 180W SFF supply that has failed, developed coil whine or lost regulation. The jump is worth it when the original unit no longer holds voltage under load or when a rebuild demands a fresh, new unit with a single cooling fan.

Fits the proprietary SFF chassis

The supply slides into the Dell SFF bay and connects through an 8-pin motherboard header and a 4-pin CPU header. Input range is 100-240V at 50/60Hz, drawing 7.0-3A. No extra cables or adapters are required for the listed OptiPlex, Inspiron and Precision models.
