ATX Power Connector - KB160 Series
Use a power supply that complies with the ATX12V Power Supply Design Guide Version 1.1.
The system board requires a minimum of 300 Watt power supply to operate. Your system
configuration (CPU power, amount of memory, add-in cards, peripherals, etc.) may exceed the
minimum power requirement. To ensure that adequate power is provided, we strongly recom-
mend that you use a minimum of 400 Watt (or greater) power supply.
Important:
Insufficient power supplied to the system may result in instability or the add-in boards
and peripherals not functioning properly. Calculating the system’s approximate power
usage is important to ensure that the power supply meets the system’s consumption
requirements.

Chassis Intrusion Connector
The board supports the chassis intrusion detection function. Connect the chassis intrusion
sensor cable from the chassis to this connector. When the system’s power is on and a chassis
intrusion occurred, an alarm will sound. When the system’s power is off and a chassis intrusion
occurred, the alarm will sound only when the system restarts.
