Genuine Asus ZenBook 14x OLED UX5400 chargers are listed below, please check your model and then select the same from below, this series will be supplied with either the 100W USB-C or 90w USB-C, so for models starting UX5400ZB and UX5400ZF then it is the 90w USB type C ac adapter needed and for the models starting UX5400EA and UX5400EG then you ned the more powerful 100w USB type C ac adapter. (which if unsure also fits with models needing less power, so if unsure this is the recommended one).
