240W replacement adapter for ROG Zephyrus M16

This 20V 12A AC adapter replaces the ADP-240EB B unit for ROG Zephyrus M16 models GU603ZX, GU603ZW and GU603ZM. It ships new with a US power cord and a 6.0 by 3.7 mm DC connector. The unit is built as a direct replacement for the original charger. Buyers with a different barrel size or voltage requirement cannot use this adapter.

Capacity and headroom for gaming loads

The adapter delivers 240W total output power at 20V 12A, matching the factory specification for the listed Zephyrus M16 laptops. It handles full CPU and GPU load while charging the battery. Over-current, over-voltage, short-circuit and total-power protection circuits guard the laptop during peak demand. The unit has no headroom beyond the rated 240W, so systems drawing more than that will trip protection.

Fits the Zephyrus M16 power port

The 6.0 by 3.7 mm barrel plugs straight into the laptop’s DC-in jack without adapters. Input accepts AC 100 to 240V for worldwide mains voltage. CE, FCC and ROHS markings confirm compliance testing. The brick frees the owner from hunting for a proprietary ASUS part number. Laptops with a different pin diameter or a USB-C power input are not compatible.

Questions about this item

Will the 20V 12A 240W output and 6.0mm by 3.7mm DC pin match the original charger on my ROG Zephyrus M16 GU603ZX?

Yes — the adapter delivers 20V at 12A for 240W total and uses a 6.0mm by 3.7mm barrel connector, which is the specification for the GU603ZX, GU603ZW and GU603ZM models.

How can I confirm the adapter is operating correctly once I plug it in?

The laptop charging indicator should light immediately and the battery icon in Windows will show it is receiving 240W; the brick runs cool thanks to over-current, over-voltage, short-circuit and total-power protection circuits that are 100% tested before shipment.

Does the package include a mains lead or do I need to buy one separately?

A US power cord is included in the box at no extra cost, so nothing else is required to start charging.
