330W AC Adapter for Alienware Desktops and Laptops

This 330W power supply delivers 19.5V at 16.9A through a 7.4mm by 5.0mm connector. It replaces the original ADP-330AB D unit for Alienware x51 desktops and M18x laptops across revisions R1, R2 and R3. The adapter accepts 100-240V input at 50-60Hz for worldwide use.

For owners replacing a failed

Buyers needing a direct replacement for the listed Dell part numbers will find the correct voltage, amperage and connector fit. Systems requiring a different wattage, voltage or connector size should look at other adapters because this unit is fixed at 330W output.

Includes US power cord and LED indicator

The package supplies the adapter and a three-prong US mains cord so the unit is ready to plug in. A built-in power LED shows when the brick is receiving mains voltage, helping confirm the wall outlet and cable are working before connecting to the computer.

Questions about this item

Does the 7.4 mm × 5.0 mm barrel connector on this ADP-330AB D adapter match the power port on my Alienware M18x R2?

The adapter uses a 7.4 mm by 5.0 mm connector, which is the standard size for the Alienware M18x, R1, R2 and R3 models listed in the compatibility data.

Will this 330 W unit safely replace the original 240 W or 330 W brick that came with my Alienware x51 desktop?

It delivers the same 19.5 V 16.9 A 330 W output and accepts 100-240 V input, so it meets the electrical requirements for the Alienware x51 and x51 R2 systems.

How can I confirm the adapter is working correctly once I plug it in?

The built-in power LED indicator lights up when the adapter is receiving mains power and delivering 19.5 V to the system.
