Precision Workstation Power

This 240 W AC/DC charger is built for Dell Precision 7720, 7730 and 7740 mobile workstations. It delivers 19.5 V at 12.3 A to match the original power requirements. Professionals replacing a lost or damaged adapter will find a direct fit.

19.5 V 12.3 A Output

The single specification that decides compatibility is the 19.5 V 12.3 A output rating. Only devices designed for this exact voltage and current will operate safely. Buyers whose laptops require a different voltage or amperage cannot use this unit.

240 W Headroom

At 240 W the adapter comfortably runs the workstation under full CPU and GPU load while charging the battery. It runs out when the system demands more than 240 W, such as configurations with higher-wattage graphics options or docks that draw additional power.
