2.6 Power Consumption
In order to ensure safe operation of the board, the ATX12V power supply must monitor the supply
voltage and shut down if the supplies are out of range – refer to the hardware manual for the actual
power supply specification. The KTQ67 board is powered through the ATX/BTX connector and
ATX+12V connector. Both connectors must be used in according to the ATX12V PSU standard.
The requirements to the supply voltages are as follows:
