Replacement AC Adapter

This WAWEIS 20V 8A 160W unit replaces the original power supply for Alienware Area-51 m766, D900K and D900T laptops. It delivers 100 percent compatibility with the listed device models and uses a 4-pin connector. The adapter accepts worldwide input voltage from 100 to 240VAC at 50 or 60Hz.

Upgrade From Worn Chargers

Swapping a failing or lost brick restores full charging speed and system stability under load. The jump is worth it when the original unit shows frayed cables, intermittent contact or overheating. Safety features include over current, over voltage, short circuit and total power protection.

Power Capacity And Limits

The 160W output comfortably handles the laptop, its battery charge cycle and connected peripherals simultaneously. A 10 ft total cord length provides placement flexibility. It is not for users needing higher wattage for desktop replacement GPUs or multi-device docking stations.

Questions about this item

Does the 4-pin connector fit the Alienware Area-51 m766 D900K D900T power port?

Yes, the adapter is built with a 4-pin connector that matches the original power port on the Alienware Area-51 m766 D900K D900T models.

How do I install this 160W adapter and what step is often missed?

Plug the mains cable into a 100-240VAC 50/60Hz socket, connect the 4-pin plug firmly until it clicks, then power on; the step often missed is ensuring the connector is fully seated before switching on the wall outlet.

Keep the 10 ft cord and ventilation slots free of dust, avoid tightly coiling the cable during storage, and replace the unit if the smart chip triggers overheating protection repeatedly.
