Compatible AC adapter for Alienware 17 R2

This 240W power supply replaces the original charger for the Dell Alienware 17 R2 notebook. It delivers 19.5V at 12.3A through a 10 ft cord. The unit is new and built to match OEM specifications.

Deciding specification — 240W at 19.5V 12.3A

The adapter provides exactly 240 watts at 19.5 volts and 12.3 amps. This output matches the power requirement of the Alienware 17 R2. A lower wattage unit would not sustain the system under load.

Sustained-load behaviour and protections

Over current, over voltage, short circuit and total power protection circuits guard the laptop during continuous operation. The 100-240VAC 50/60Hz input handles worldwide mains voltage without a separate converter. FCC, CE and RoHS certifications confirm compliance with safety standards.
