Power Consumption

In order to ensure safe operation of the board, the ATX power supply must monitor the supply voltage and
shut down if the supplies are out of range – refer to the hardware manual for actual power specification.
The KT690/mITX and KT690-FW/mITX board is powered through the ATX connector and the additional 12V
separate supply for CPU as specified in the ATX specification; besides this the power supplied to the board
must be within the ATX specification.
The requirements to the supply voltages are as follows:
