Power delivery

This genuine Dell 330 W charger supplies 19.5 V at 16.9 A through a 7.4 mm by 5.0 mm barrel connector. It accepts worldwide mains input from 100 V to 240 V at 50 Hz or 60 Hz and includes the matching power cord. The unit is designed for Alienware M18x series laptops, Alienware X51 R1 and R2 desktops, and Precision M6600 and M6700 mobile workstations.

Connector verification

Confirm that the original adapter tip measures 7.4 mm outer diameter and 5.0 mm inner diameter before ordering. Cross-reference your laptop service tag or the part numbers listed — XM3C3, 0XMC3, 5X3NX, D37NX, R5MR2, Y90RR, 0Y90RR, ADP-330AB, DA330PM111, 332-1432, 450-18939, 450-18980 — to ensure an exact match. Supplying a different tip size will prevent the charger from seating or delivering power.

Sustained output behaviour

The adapter maintains its full 330 W rating during extended gaming or rendering sessions on compatible Alienware and Precision systems. Thermal protection regulates temperature without throttling the rated current, so the 19.5 V rail remains stable under continuous load. Buyers needing higher wattage for newer multi-GPU configurations or larger workstation chassis will need a different power solution.

Questions about this item

Does the 330 W charger ship with a mains cable or must one be sourced separately?

A power cord is included with the adapter so no separate cable purchase is required.

How do I confirm the 7.4 × 5.0 mm tip matches the Dell model I own?

Compare the tip size and the part numbers listed — XM3C3, 0XMC3, 5X3NX, D37NX, R5MR2, Y90RR, 0Y90RR — against your current charger or laptop service tag.

What does the 330 W rating mean when the adapter is connected to an Alienware M18x?

It delivers 19.5 V at 16.9 A, providing the full power budget the M18x needs for high-load components such as the GTX 860M graphics.
