Purpose-built power for ASUS ROG Mothership

This 280 W AC adapter is engineered for the ASUS ROG Mothership GZ700GXRTX2080. It delivers a steady 20 V at 14 A through a 7.4 mm by 5.0 mm barrel connector. The unit replaces the original ADP-280BB B brick for owners who need a direct spare.

Single-voltage output limits flexibility

The adapter provides only the fixed 20 V rail required by the host laptop. It cannot negotiate lower voltages for other devices, so it is unsuitable as a universal charger. The 280 W ceiling also means it will not support higher-wattage workstations or multi-GPU docks.

OEM-spec housing with standard barrel fit

The moulded enclosure matches original dimensions and meets the same safety specifications. The 7.4 mm by 5.0 mm tip seats securely in the Mothership’s power jack without wobble. A 12-month warranty backs the build, with a 60-day free replacement window if the unit arrives defective.
