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.
