330W AC Adapter for ROG Laptops

This 330 watt AC adapter replaces the original power supply for compatible ROG Strix and Zephyrus Duo models. It accepts a wide AC input range of 100 to 240 volts at 50 to 60 hertz and delivers 20 volts at 16.5 amps. The unit matches part numbers A21-330P1A and A22-330P1A. It is sold new and ready for immediate use.

Suits owners of listed ROG models

This adapter fits ROG Strix G16, G17 and G18 series including Scar 16, 17 and 18 variants. It also supports ROG Zephyrus Duo 16 models such as GX650PY, GX650PZ and GX650PI. Buyers with laptops outside these specific model families should look for a different charger. The connector and voltage must match the original unit exactly.

330 watt output decides compatibility

The single specification that determines fit is the 330 watt power rating combined with 20 volt 16.5 amp DC output. Only laptops designed for this exact wattage and voltage should use this adapter. Lower wattage units will not provide enough power for RTX 4060 4070 4080 4090 equipped models. Higher wattage is not required for these systems.
