MSI 400 W AC Adapter 18221P108
This 400-watt AC adapter is built for high-performance MSI laptops such as the Titan 18HX and Creator Pro HX. It replaces a lost or damaged original charger and restores full power delivery for demanding workloads. The unit is supplied new and ready for immediate use.
Replaces original charger or lower-wattage units
A 400 W adapter is required when the laptop draws peak power for intensive tasks such as rendering or gaming. Using a lower-rated charger can throttle performance or prevent charging under load. The jump is worth it whenever the original 400 W brick is missing or has failed.
Barrel-connector AC input limits
The adapter uses a proprietary barrel connector that fits only compatible MSI models. It cannot charge laptops that require USB-C Power Delivery or a different pin layout. Polarity and tip dimensions must match the device exactly or the unit will not connect.
