Thermal Dissipation

4 Thermal Dissipation
Each power supply dissipates, i.e., loses energy in form of heat. The graphs below illustrate
typical power dissipation values in watt (W) for one segment for given output currents and
supply voltages. These include the power dissipation of the motherboard.
