Description
Dynamic power adjustment
Three selectable operating modes allow the system to scale flexibly from low-noise operation (15 W) to peak performance (35 W).
Efficient Dual fan system
Separate fans for CPU and system components, in combination with copper heat pipes, provide low temperatures and reduced noise emissions.
Extensive interfaces
A USB4 connection at the back and a USB-C port at the front offer high data rates and Power delivery input. Further USB-A connections facilitate the peripheral connection.
