This 200W AC adapter delivers 20V at 10A for compatible ASUS ROG Zephyrus G15 models including GA503QM, GA503QS and GA503QR. It replaces part number ADP-200JB D and features a 6.0×3.7mm DC connector. The unit accepts 100-240V input at 50-60Hz for worldwide use.

Included Power Cord and Protections

The package supplies one AC adapter and one AC power cord so the laptop can be powered immediately. Built-in safety features include V-0 grade flame-retardant materials plus over-voltage, over-current and short-circuit output protection. The adapter meets CE, FCC and RoHS standards and is 100% tested before delivery.

200W Capacity for Gaming Laptop Loads

Rated at 200W, the adapter comfortably handles the power draw of the supported Zephyrus G15 gaming laptops during intensive workloads.

Questions about this item

How often should the 6.0×3.7mm DC connector be inspected or replaced under normal use?

Inspect the connector whenever the adapter is unplugged; replace it if the pin feels loose, shows bent contacts or the cable sheath is frayed near the plug.

Which protection circuit — OVP, OCP or SCP — typically activates first during a sustained 200W load?

Over Current Protection (OCP) is designed to trip first if the 10A output limit is exceeded during prolonged high-power operation.

Does the V-0 flame-retardant casing keep the brick cool enough for 24-hour continuous use?

The V-0 rating covers fire safety, not temperature; the adapter will warm up during all-day 200W use, so keep ventilation clear around the unit.
