SKU CH-E55Y-MXCAH

A 120 W AC/DC replacement adapter for ASUS VG28U and VG28UQL1A monitors with 100–240 V input and a 10 ft cord

  • World-wide 100-240 V input works anywhere
  • 120 W output matches the monitor’s original supply
  • 10 ft total cord length gives flexible placement
  • Over-current, over-voltage and short-circuit protection guards the display
  • FCC, CE and RoHS certified for safety compliance

Direct replacement for ASUS VG28U

This 120W AC/DC adapter matches the original ADP-120VH B specification and part number 90LM0780-B011B0. It restores power to the 28-inch 4K TUF Gaming display when the factory unit is lost or damaged. The package includes a 10 ft power cord for flexible desk placement. Buyers needing a different wattage or connector type should look elsewhere.

Universal 100-240VAC input

The adapter accepts mains voltage from 100 to 240VAC at 50/60 Hz for worldwide use. Built-in safeguards include over-current protection, over-voltage protection, short-circuit protection and total power protection. A smart chip adds over-heating protection while isolation materials reduce interference. These features keep the monitor running steadily during long sessions.

FCC, CE and RoHS certified

The unit carries FCC, CE and RoHS certifications confirming compliance with safety and environmental standards. A 10 ft cable reaches distant outlets without strain on the monitor port. The barrel connector seats securely in the ASUS VG28U and VG28UQL1A jack. Users requiring an angled plug or a shorter cable will need a different adapter.

Questions about this item

How do I connect the adapter to the ASUS VG28U monitor and what step is often missed?

Plug the DC barrel connector into the monitor's power input, then attach the supplied AC cord to the adapter and a 100-240VAC 50/60Hz wall outlet; the step often missed is seating the barrel plug fully until it clicks.

Which parts of this 120W adapter may need replacement after extended use?

The detachable AC cord and the DC cable can wear from bending; the adapter body itself has no user-serviceable parts and is designed to last the monitor's lifetime.

What is the first limit reached when the adapter runs continuously at full 120W load?

The over-current protection trips first if the monitor draws more than the rated 120W, shutting off output until the load drops and the adapter cools.
