330 W 19.5 V AC adapter for Alienware desktops

This replacement power supply delivers 330 W at 19.5 V and 16.9 A through a 7.4 mm by 5.0 mm barrel connector. It accepts 100-240 V input at 50-60 Hz and includes a three-prong outlet plug and a power LED indicator. The unit is built for Dell Alienware x51 desktops and Alienware M18x R1, R2 and R3 laptops.

Replaces original ADP-330AB and DA330PM111 units

The adapter matches part numbers F0K0N, 331-2429, 320-2269, XM3C3, ADP-330AB B, ADP-330AB D, DA330PM111 and CN-0XM3C3. It is a direct swap when the original 330 W brick fails or is lost. The jump is worth it when the system shows charging faults, intermittent power or a damaged cable on the factory supply.

Fits x51 and M18x chassis with 7.4 mm barrel jack

The connector size and 19.5 V output align with the x51 desktop and M18x series power jack, freeing the builder from hunting proprietary Dell bricks. A standard IEC C13 mains lead completes the connection. Buyers needing a different voltage, a higher wattage or a USB-C PD interface cannot use this adapter.
