330W 19.5V AC adapter for Alienware X51 R2

This 330-watt AC adapter supplies 19.5 volts at 16.9 amps to Dell Alienware X51 and X51 R2 gaming desktops. The 7.4 by 5.0 mm barrel connector with a central pin matches the original DC jack. Built-in over-current, over-voltage, short-circuit and total-power protection circuits guard the system during load spikes.

Replaces worn or lost 330W Dell DA330PM111 units

The adapter substitutes for Dell part numbers 0XM3C3, XM3C3, DA330PM111, 0Y90RR, Y90RR, F0K0N, 331-2429, 450-17280, ADP-330AB B, 5X3NX, 332-1432 and ADP-330AB D. The upgrade is worthwhile when the original brick fails, shows intermittent charging or cannot sustain peak GPU loads on the X51 platform.

Limited to 100-240V AC input

The unit accepts 100 to 240 volts AC at 50 to 60 hertz and delivers a single 19.5-volt DC rail at up to 16.9 amps. It cannot power devices that require a different voltage, current limit or connector geometry, and it is not suitable for laptops or other desktops outside the listed Alienware models.

Questions about this item

Will the 7.4 mm × 5.0 mm barrel connector with central pin fit my Alienware X51 R2?

Yes, the connector matches the 7.4 mm outer diameter, 5.0 mm inner diameter and centre-pin layout used by the X51 and X51 R2 power port.

What is the correct order to connect the adapter so the centre pin makes contact first?

Plug the AC cord into the adapter, insert the DC barrel fully until the centre pin seats, then connect the AC cord to mains power.

When should I replace the AC power cord that ships with the 330 W unit?

Replace the cord if the USA plug blades are bent, the insulation is cracked, or the cord becomes warm during normal 19.5 V 16.9 A operation.
