90W AC adapter for MSI Modern laptops

This 90W AC adapter delivers 19V at 4.74A and matches the original MSI 957-14D22P-103 unit. It powers compatible Modern 14 and Modern 15 models including B11SB, B11SBL, B11SBU, A11SB, A11SBL, A11SBU and B12HW series. The adapter accepts worldwide AC input from 100 to 240V at 50 to 60Hz.

Capacity and headroom: 90W continuous output

Rated at 90W maximum, the adapter supplies 19.5V 4.62A, 19V 4.74A or 20V 4.5A depending on the connected device. It comfortably handles full-load charging and operation for the listed ultraportables. Systems requiring more than 90W or a different voltage profile will exceed its capability.

Practical limits of the barrel connector interface

The fixed barrel tip fits only the MSI models named in the compatibility list. Laptops with USB-C charging, proprietary slim tips or higher wattage requirements cannot use this adapter. The six-foot AC cord and six-foot DC cord provide reach but do not alter the electrical limits of the single-output design.
