240W AC adapter for Alienware and Precision

This 19.5V 12.3A AC adapter delivers 240W of power through a 7.4mm tip with a centre pin. It is designed for Alienware 15, 17, m15, m17, m18, m18x, x15, x16, x17 and x51 models across R1 to R5 revisions. It also supports Dell G5 5505, G15 5515, G5530, G7500, G7630, G7700 and Precision 7670, 7680, 7710, 7720, 7730, 7740, 7750, 7760, 7770, 7780, M6700 and M6800 workstations.

Check your current adapter wattage and tip size

Verify that your original charger is rated at 180W, 230W or 240W; this unit does not replace 280W, 300W or 330W adapters. Confirm the laptop uses a 7.4mm barrel connector with a centre pin as shown in the product images. Ensure the input voltage range matches your local mains supply before connecting the 6 ft UL-listed AC cord.

Durable sealed case with extra-long cables

The adapter housing is built to resist extreme conditions and seals out water and humidity for everyday reliability. A 6 ft DC cable and a separate 6 ft AC power cord provide extended reach without needing extension leads. Built-in overload, short-circuit, over-voltage, over-current and over-temperature protection safeguards both the adapter and the connected laptop during daily use.

Questions about this item

Does the box include both the AC power cord and the DC cable or must I buy one of them separately?

The package includes a UL listed 3-prong AC power cord and a DC power cord, each 6 ft long, so no separate cord purchase is needed.

My Dell Precision 7740 shipped with a 230W adapter — will this 240W unit work or should I look for a different wattage?

This 240W adapter replaces Dell 180W, 230W and 240W chargers; it is not a replacement for 280W, 300W or 330W units.

The tip is described as 7.4 mm with a centre pin — does that match the barrel connector on an Alienware x17 R2?

Yes, the 7.4 mm plug with centre pin fits Alienware 15, 17, m15, m17, m18, m18x, x15, x16, x17 and x51 models including R1 through R5 revisions.
