KT690 Family
KTD-00738-J Public User Manual Date 2012-06-01 Page 19
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:
Supply Min Max Note
Vcc3 3.14V 3.46V Should be
±5% for compliance with the ATX specification
Vcc 4.75V 5.25V Should be
±5% for compliance with the ATX specification
+12V 11.4V 12.6V Should be
±5% for compliance with the ATX specification
–12V –13.2V –10.8V Should be
±10% for compliance with the ATX specification
-5V -5,50V -4.5V Not required for the KT690/mITX board
5VSB 4.75V –5.25V Should be
±5% for compliance with the ATX specification
Static Power Consumption
The power consumption of the KT690/mITX and KT690/mITX-FW Board is measured under:
1- WindowsXP, Running 3DMARK & CPU BURN, mean
2- WindowsXP, Running 3DMARK & CPU BURN, peak
3- S1, mean
4- S3, mean
5- Inrush, peak
