65W AC adapter for OptiPlex Micro

This 65 watt AC adapter delivers 19.5 volts at 3.34 amps and also covers the 45 watt 2.31 amp requirement for Dell OptiPlex Micro desktops. It accepts a universal 100 to 240 volt input at 50 to 60 hertz. The 4.5 by 3.0 millimetre three-prong connector matches the original factory specification. It is intended for owners of compatible OptiPlex Micro units who need a direct replacement power supply.

Thermal performance and power draw

The adapter operates from standard mains voltage without requiring a separate voltage selector. Built-in overload, over-voltage and short-circuit protection circuits limit stress on internal components during normal use. No active cooling fan is present, so acoustic output remains negligible in a typical office environment. Power consumption scales with the connected Micro desktop load up to the rated 65 watt maximum.

Bundled power cord and protection features

The package includes one AC adapter and one detachable AC power cord, providing a complete connection from wall outlet to desktop. Integrated protection circuits guard the host system against overload, over-voltage and short-circuit events without additional software configuration. Buyers who need a higher wattage unit for larger form-factor OptiPlex models cannot use this adapter.

Questions about this item

How do I install the 4.5*3.0 mm connector on my OptiPlex Micro desktop?

Align the 4.5*3.0 mm barrel tip with the DC-in jack, push straight in until it clicks, then plug the 3-prong IEC cord into a 100-240V 50-60Hz outlet. The step people miss is seating the barrel fully before applying mains power.

What maintenance or replacement will this 65W adapter need later?

The AC power cord and the 3-prong inlet are the only user-serviceable parts; replace the cord if the insulation cracks or the plug loosens. The adapter body has built-in overload, over-voltage and short-circuit protection and is not designed for internal repair.

What limit appears first when the 65W unit runs continuously at full load?

Sustained 19.5V 3.34A output makes the internal thermal protection the first limit; the adapter will throttle or shut down until it cools rather than exceed its 65W rating.
