Not for MT DT or USFF chassis

Buyers with Mini Tower Desktop or Ultra Small Form Factor Optiplex models should look elsewhere because this unit is keyed for the SFF case only. It also will not suit builds that need more than 240W or connectors beyond the three listed.

Connector set decides fit

The fixed cable bundle provides P1 24-pin ATX power P2 4-pin ATX power and P3 Sata power with no modular options. Match these exact headers to your motherboard and drives before ordering.

Questions about this item

Will this 240W unit fit a Dell Optiplex 7010 Small Form Factor chassis?

Yes, it is built for Dell Optiplex 390 790 990 3010 7010 9010 Small Form Factor systems only and replaces part numbers such as H240As-00 H240Es-00 D240Es-00.

Which power connectors must be attached during installation?

Connect the 24-pin ATX main connector, the 4-pin ATX CPU connector and the SATA power leads; the step often missed is seating the 4-pin CPU plug firmly.

When should the internal fan be cleaned to keep airflow steady?

Blow dust from the fan vents every six to twelve months depending on environment; no user-serviceable parts inside so replacement means swapping the whole 240W unit.
