240W AC adapter for Dell workstations

This 19.5V 12.3A unit powers Alienware 16 and 16X models alongside Precision 7530, 7540, 7550 and M2800, M4600, M4700, M4800 workstations. It replaces original Dell 180W, 230W and 240W chargers with a 7.4x5.0mm centre-pin tip.

240W output headroom and limits

The adapter delivers 240W maximum, covering systems originally shipped with 180W, 230W or 240W bricks. It will not support laptops that require a 280W, 300W or 330W power source, so buyers needing higher wattage must look elsewhere.

7.4x5.0mm centre-pin connector

The plug tip measures 7.4 by 5.0 millimetres with a centre pin inside and is explicitly not the 9.0x6.2mm variant. This single physical interface decides compatibility; verify the original adapter tip before purchase.

Questions about this item

Will this 240 W adapter run my Dell Precision 7550 alongside the older 180 W brick I still own?

Yes — it replaces Dell 180 W, 230 W and 240 W chargers, so the Precision 7550 will draw the 19.5 V 12.3 A it needs while the older brick stays as a spare.

How can I confirm the 7.4 × 5.0 mm tip with centre pin is seated correctly after plugging it in?

The laptop charging LED should light immediately and the battery icon in Windows will show “Plugged in, charging” once the tip is fully inserted.

Does the box include both the 6 ft AC cord and the 6 ft DC cord, or must I buy one separately?

Both cords are supplied — a UL-listed 3-prong AC cable and a matching DC cable — so nothing extra is required to start charging.
