Questions about this item

Will the 7.4 mm by 5.0 mm barrel connector on this 280 W adapter fit the power port on my ASUS ROG Mothership GZ700GX?

Yes, the 7.4 mm outer and 5.0 mm inner diameter match the original ADP-280BB B specification for the GZ700GX series.

How can I confirm the 20 V 14 A output is stable after I plug it in?

The laptop should charge without throttling and the battery indicator will show a steady charging state under full load.

Does the package include a mains lead or only the 280 W brick?

Only the AC adapter brick is supplied; a compatible IEC C5 mains cable must be purchased separately.
