What this adapter is

This 240 W AC adapter replaces the original ADP-240EB B unit for ASUS ROG Zephyrus and Strix laptops. It delivers 20 V at 12 A through a 6.0 × 3.7 mm barrel plug. The unit is new and built to match the factory power specification for the listed models.

Thermals noise and power draw

The adapter supplies a steady 240 W output with no moving parts, so it runs silently. Normal operation produces only modest warmth across the brick casing. Power draw from the wall scales with the laptop load up to the rated 240 W maximum.

The deciding specification

Output is fixed at 20 V 12 A 240 W with a 6.0 × 3.7 mm connector. Do not buy if your laptop requires more than 240 W or uses a different plug size or voltage. Check the model label on your original charger to confirm it reads ADP-240EB B before ordering.

Questions about this item

How do I install the ADP-240EB B adapter and which step do people often miss?

Connect the 6.0 * 3.7 mm barrel plug firmly into the laptop's DC-in jack until it seats, then plug the IEC C5 cord into the brick and the wall outlet; the step often missed is verifying the laptop requires exactly 20V 12A 240W and not a higher-wattage unit.

What maintenance or replacement will this 240W charger need over time?

The detachable IEC C5 mains cord can be replaced if the plug or cable frays; the brick itself has no user-serviceable parts, so replace the whole unit if output voltage drifts or the barrel connector becomes loose.

What limit appears first when this adapter runs at full 240W load for long periods?

Thermal protection will throttle or shut down the brick before any other limit is reached, so keep ventilation slots clear and avoid stacking items on the enclosure during sustained 20V 12A operation.
