Replacement charger for Zephyrus GA502 GA401

The usbroway 180W 20V 9A adapter matches the original ADP-180TB H specification and ships with a 6.0x3.7mm barrel connector. It is built for owners of Asus ROG Zephyrus G GA502, GA502D, GA502DU and GA401 series laptops who need a direct replacement. The unit accepts 100-240V 50-60Hz input for worldwide use.

Thermals noise and power draw

Rated at 180W continuous output, the brick delivers 20V at 9A without exceeding its design limits in normal charging scenarios. The supplied power cord and adapter body run at typical temperatures for a 180W class supply. No active cooling is present, so operation is silent.

Sustained load behaviour

Under prolonged gaming or rendering sessions the adapter maintains its 180W rating rather than throttling to a lower figure. It is not compatible with Asus 200W 20V 10A, 230W 19.5V 11.8A, 240W 20V 12A or 280W 20V 14A models, so systems requiring those higher ratings will not charge correctly.

Questions about this item

How do I connect the 6.0x3.7mm barrel tip to my Asus ROG Zephyrus GA502DU, and what step do people miss?

Align the centre pin and outer sleeve, push straight in until the connector seats firmly; the step often missed is verifying the laptop requires exactly 20V 9A 180W and not a higher-wattage 200W or 240W unit.

What part of this 180W adapter will need replacement first under normal use?

The detachable mains cord and the barrel-tip cable are the wear items; the brick itself has no user-serviceable parts and typically outlasts the cables.

What thermal or power limit appears first when this 180W charger runs at full load for long periods?

The 20V 9A 180W output rating is the hard ceiling; sustained loads at that level will hit the adapter's maximum continuous power before any other limit.
