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:
Supply Min Max Note
VCC3.3 3.135V 3.465V Should be
±5% for compliance with the ATX specification
Vcc 4.75V 5.25V Should be
±5% for compliance with the ATX specification.
Should be minimum 5.00V measured at USB connectors
in order to meet the requirements of USB standard.
+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 KTQ67 board
5VSB 4.75V 5.25V Should be
±5% for compliance with the ATX specification
