myVolts 240W AC Adapter 19.5V 12.3A 7.4mm x 5.0mm

SKU CH-VXJ3-072BD

240W laptop power supply delivering 19.5V at 12.3A through a 7.4mm x 5.0mm connector, compatible with Dell Precision and Alienware models

  • Works worldwide with 100-240V input
  • Delivers 240W at 19.5V 12.3A for high-performance laptops
  • Fits Dell Precision and Alienware models with 7.4mm x 5.0mm connector
  • Certified UL CE FCC RoHS with over-voltage and over-heat protection
  • Replaces multiple Dell part numbers including PA-9E and ADP-240AB

240W Dell Compatible Adapter

This 240W AC adapter delivers 19.5V at 12.3A through a 7.4mm x 5.0mm barrel connector with centre pin. It replaces original Dell PA-9E family units for Precision mobile workstations and Alienware gaming laptops. The unit ships new with a detachable mains lead included.

Input Range and Connector Fit

The adapter accepts 100V to 240V at 50Hz to 60Hz, drawing up to 3.5A, so it works on mains supplies worldwide without a voltage switch. Output is fixed at 19.5V and 12.3A; the 7.4mm x 5.0mm plug must match the laptop socket exactly or the device will not seat. No other connector sizes or output voltages are supported by this model.

Replaces 180W and Lower Dell Bricks

This unit supersedes Dell 180W and lower-wattage chargers such as ADP-180 and PA-6E variants used on the same Precision and Alienware chassis. The higher 240W headroom prevents throttling when discrete GPUs and CPU turbo boost run simultaneously. It is not for laptops that require 330W adapters or proprietary Dell USB-C power delivery.

Questions about this item

Should I choose this 240W adapter or an 180W version for my Precision 7730?

This 240W unit replaces both 240W and 180W Dell parts, so it covers the higher draw of the Precision 7730 and earlier 7720 models without needing a separate lower-wattage supply.

What does the 19.5V 12.3A rating deliver inside the laptop?

The 19.5V output at 12.3A provides the full 240W the Precision 7730 and Alienware M18x R2 require under load, keeping CPU and GPU clocks stable while charging the battery.

Does the 7.4mm x 5.0mm centre-pin connector fit the Precision 7720 and Alienware 17 R5?

Yes, the 7.4mm x 5.0mm barrel with centre pin matches the Dell PA-9E family used on Precision 7720, 7730, Alienware 17 R5 and the listed M18x models.
