KT690 Family
Power Consumption 3.7
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/mITX-FW 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:
Should be ±5% for compliance with the ATX specification
Should be ±5% for compliance with the ATX specification
Should be ±5% for compliance with the ATX specification
Should be ±10% for compliance with the ATX specification
Not required for the KT690/mITX board
Should be ±5% for compliance with the ATX specification
