65W 19V AC Adapter for Asus Laptops

This 65-watt AC adapter supplies 19 volts at 3.42 amps for compatible Asus notebooks including the X401, X501, X550 and X551 series. It accepts a universal 100 to 240-volt input at 50 to 60 hertz for worldwide use. The unit is intended as a direct replacement for original Asus part numbers such as ADP-65DW B and ADP-65GD B. Buyers who need a higher-wattage 90-watt supply or a different connector size cannot use this adapter.

Simple Plug-In Replacement With Fixed Tip

Installation requires only connecting the barrel plug to the laptop DC jack and the IEC mains lead to a wall socket. The connector measures 5.5 by 2.5 millimetres and is permanently attached, so there are no interchangeable tips to lose or misalign. The most common issue is ordering this 65-watt model for a system that requires 90 watts or more, which will prevent charging or cause the adapter to overheat. Verifying the original adapter's output rating and tip dimensions before purchase avoids that mismatch.

5.5×2.5 mm Barrel Connector Decides Fit

The single specification that determines compatibility is the 5.5-millimetre outer diameter and 2.5-millimetre inner diameter barrel connector paired with the 19-volt 3.42-amp output. Only Asus models listed in the compatibility data that use this exact tip size and power rating will work correctly. If the laptop requires a different connector geometry or a higher current rating, this adapter will not fit or supply sufficient power.

Questions about this item

How can I confirm the adapter is delivering the rated 19V 3.42A output after connecting it?

The laptop should power on and charge the battery normally; a steady charging LED on the notebook indicates the 65W supply is operating within its specified range.

What cables are included and is a mains lead supplied?

The unit integrates the DC cable with a 5.5×2.5mm barrel tip; a detachable AC mains cord for the 100-240V inlet is not included and must be purchased separately.

Which connector size matches the Asus X551 series — 5.5×2.5mm or a different tip?

The adapter uses a 5.5×2.5mm barrel connector, the exact size listed for the X551, X550, X501 and X401 families in the compatibility data.
