9.5W2Maker product pagepsref.lenovo.com/Detail/ThinkVision/ThinkVision_M14t_Gen_2Read 8 October 2026Current exact 63FDUAT6WL PSREF publishes 9.5 W maximum power consumption, corroborated by July 2026 platform PSREF and current maker datasheet. Original guide lists 8.5 W without Type-C output and separately 83 W including passthrough draw. Current exact maximum claim takes precedence over the old guide figure. PSREF does not state USB passthrough load allocation or test settings. The reason for the difference is not established. Separate 65 W output is not added to invent total draw.
