240W Adapter for Alienware & Dell

This 240 watt AC adapter supplies 19.5 volts at 12.3 amps through a 7.4 by 5.0 millimetre barrel plug with a centre pin. It replaces part numbers GA240PE1-00, LA240PM160 and ADP-240AB on compatible Alienware and Dell laptops. The unit accepts 100 to 240 volt input at 50 to 60 hertz for worldwide use.

For owners of listed Alienware and Precision models

Buyers with an Alienware M17X R1, R3, R4, 15 R2, Precision M4700, M6600 or M6700, plus Latitude 5500 and G5 5500 units requiring this exact connector, can use this adapter. Users whose laptops demand a different voltage, amperage or barrel size should look elsewhere, as mismatched power can damage the notebook.

7.4x5.0mm centre-pin barrel connector

The single specification that decides fit is the 7.4 millimetre outer diameter, 5.0 millimetre inner diameter barrel plug with a centre pin. Only laptops designed for this exact connector and the 19.5 volt 12.3 amp output will work safely with this 240 watt supply.
