Replacement 240 W AC adapter

The iTekiro adapter delivers 20 V at 12 A for a 240 W output through a 4.5 mm barrel plug with a centre pin. It is built for MSI Crosshair 18 HX AI A2XWGKG and Katana 15 HX B14W series laptops that require this exact voltage and connector.

Upgrade path from lower-wattage chargers

It replaces MSI 180 W, 200 W, 230 W and 240 W units, so owners of those chargers can move to this model without changing tip or voltage. The jump is not worth it for systems that ship with a 280 W, 300 W or 330 W brick because the adapter cannot supply the higher current those machines expect.

Build integration with long cables

A UL-listed 6 ft AC cord and a 6 ft DC cord give twelve feet of total reach, reducing the need for extension leads on a desk or bench. The ruggedised case resists water and humidity, so the unit survives travel in a bag alongside the laptop. The centre-pin connector mates only with compatible MSI ports, preventing accidental mis-connection.

Questions about this item

Will the 4.5 mm centre-pin connector fit the MSI Crosshair 18 HX AI A2XWGKG?

The 4.5 mm diameter plug tip with a centre pin is designed for the listed MSI Crosshair 18 HX AI A2XWGKG and Katana 15 HX B14W models.

How do I install the adapter and which step is often missed?

Plug the 6 ft 3-prong AC cord into the wall, connect the 6 ft DC cord to the laptop, and ensure the centre pin seats fully in the 4.5 mm jack.

What maintenance or replacement will this 240 W adapter need later?

No routine maintenance is required; replace the unit if the cords fray, the connector loosens, or output drops below the 20 V 12 A rating.
