280 W AC adapter for ROG laptops

This 280 W AC adapter delivers 20 V at 14 A through a 6.0 × 3.7 mm barrel connector. It is built for ROG Flow X16, Strix G15, G16, G17, G18, Scar 15, Scar 17 SE, Zephyrus M16 and TUF Gaming A16 models. The unit accepts 100–240 V input at 50–60 Hz for worldwide use. Buyers who need a different connector size or a lower-wattage supply cannot use this adapter.

Thermals noise and protection

An internal IC chip provides over-current, over-voltage, short-circuit and over-temperature protection during normal operation. The cable uses high-density PC material for wear resistance and durability. A separated line-body design reduces tangling and strain on the connectors. No fan is present so the adapter runs silently.

Sustained load behaviour

Under continuous 280 W draw the protection circuits maintain stable output without shutdown. The robust cable construction resists heat build-up over long charging sessions. The package includes one AC adapter and one power cord. Users who require a higher continuous power rating or a different output voltage must choose another unit.

Questions about this item

How do I install the ADP-280EB adapter, and what step do people often get wrong?

Plug the 6.0 x 3.7 mm barrel tip firmly into the laptop’s DC jack until it seats, then connect the supplied power cord to the adapter’s IEC C5 inlet and a 100 V – 240 V wall outlet. The step people miss is verifying the tip polarity and dimensions against the original charger before first use.

What maintenance or replacement will this 280 W adapter need later?

The detachable power cord can be swapped if the IEC C5 connector or cable sheath wears out. The adapter body itself is sealed; if the built-in protection IC triggers over-current, over-voltage, short-circuit or over-temperature shutdown repeatedly, replace the whole unit.

What limit appears first when the ADP-280EB runs at full 280 W load for long periods?

Internal temperature rise triggers the over-temperature protection first. The adapter will shut down until it cools, so keep ventilation slots clear and avoid stacking items on the brick during sustained 20 V 14 A output.
