Compatible replacement charger for listed MSI models

This 19V 3.42A 65W AC adapter from Chicony is a new replacement power supply for the specified MSI laptop series. It matches the required voltage and current ratings and uses a 5.5 x 2.5mm barrel connector. The unit has passed UL safety testing and includes a US cable plug for mains connection.

Replaces a lost or failing original adapter

When the original charger is missing, damaged, or no longer holds a charge, this unit restores full power delivery without modification. The jump is worth it if the laptop will not start or the battery refuses to charge with the old supply. It covers the CX, CR, EX, FX, GE and related model families listed in the compatibility data.

Delivers 65W for standard workloads

The adapter comfortably handles everyday office tasks, web browsing and media playback on the supported notebooks. It runs out of headroom when the system demands sustained loads above 65W, such as discrete GPU gaming or heavy rendering, which may cause the supply to overheat or the laptop to throttle.

Questions about this item

Will the 5.5 mm by 2.5 mm barrel connector fit my MSI CX605 charging port?

Yes, the adapter uses a 5.5 x 2.5 mm centre-positive barrel plug that matches the CX605 DC-in jack.

What is the common mistake when plugging this adapter in for the first time?

Connecting the barrel tip before the AC cord is fully seated in the brick can leave the laptop without power.

How often should I replace the detachable US power cord?

Replace the cord if the insulation cracks, the plug prongs loosen, or the connector feels hot during use.
