This 240-watt replacement charger supplies 19.5 volts at 12.3 amps through a 7.4mm by 5.0mm barrel connector. It accepts 100-240 volt input at 50-60 hertz and also covers 180W, 150W and 130W requirements. The package includes the AC adapter and a power cord. It is CE, FCC and ROHS certified.

Suits Dell Alienware and Precision owners needing

Buyers with Dell Alienware M17X, M18X, X51, 15, 17 or Precision 7510, 7520, 7530, 7710, 7720, 7730 models using the listed part numbers can use this adapter. Users whose laptops require a different connector diameter or a higher wattage than 240W should look elsewhere.

Connector size 7.4mm by 5.0mm decides fit

The barrel plug measures 7.4mm outer diameter by 5.0mm inner diameter. Match this exact dimension to the laptop's power jack before ordering; an incorrect tip will prevent connection regardless of wattage or voltage compatibility.

Questions about this item

Does my laptop need a 7.4mm by 5.0mm barrel connector for this charger to fit?

Yes, the connector measures 7.4mm by 5.0mm and matches the Dell part numbers listed including PA9E, 330-3514, J211H, Y044M and 450-AGCX.

Will this 240W adapter safely run on a Dell Precision 7510 that originally used a 180W or 150W supply?

The unit delivers 19.5V at up to 12.3A and is also rated for 19.5V 9.23A 180W and 19.5V 6.7A 130W, so it covers those lower-wattage models.

How can I confirm the adapter is operating correctly once connected?

The laptop should show it is charging, the power LED on the adapter stays solid, and the system reports the correct wattage in BIOS or the Dell power manager.
