ATX Power Connector - BT160
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.
