The single specification that decides fit is the 20 volt 12 amp 240 watt output combined with the 6.0 by 3.7 millimetre DC connector. If your device requires a different voltage, amperage or plug geometry this adapter will not work.

Yes, it is compatible with 180W and 200W ROG Zephyrus models because the laptop only draws the power it needs.

How can I confirm the adapter is delivering the correct 20V 12A output after I plug it in?

The laptop’s battery indicator should show charging at full speed and the adapter’s LED (if present) will stay solid, confirming 20V 12A delivery.
