Power Adapter For MSI Laptops

This 150 W AC adapter supplies 19.5 V at 7.7 A through a 5.5 x 2.5 mm barrel connector. It is designed as a direct replacement charger for specific MSI notebook models including the GP73, GS63VR, GS70 and GS60 series listed in the compatibility data.

Installation And Common Issues

The adapter plugs into a standard IEC C5 or C7 mains lead (US, EU, UK or AU cord included) and the barrel tip inserts into the laptop DC jack. Most installation problems arise when the tip dimensions do not match the laptop socket exactly, or when the laptop requires a different wattage or voltage than the 150 W 19.5 V this unit provides.

Interface And Power Limits

The barrel connector follows a common 5.5 mm outer and 2.5 mm inner diameter format, but polarity and mechanical fit vary by manufacturer. This unit delivers a fixed 19.5 V output up to 150 W; it cannot negotiate higher voltages or currents, so it will not power devices that require USB Power Delivery or other proprietary charging protocols.

Questions about this item

How can I confirm the adapter is delivering the correct 19.5 V 7.7 A output after connecting it?

The laptop should power on and charge the battery without error messages; the adapter label shows 19.5 V and 7.7 A for reference.

What does the package contain and is a power cord included?

The box includes one AC adapter and one power cord with a plug for US, EU, UK or AU sockets.

Which compatible part number should I choose if my machine is listed as MS-16P6 or MS-16J9?

Both model numbers appear in the compatibility list, so the A14-150P1A adapter with the 5.5 x 2.5 mm plug is the correct match.
