2.6.9 Power Connectors

We recommend that you use a power supply that complies with the
ATX12V Power Supply Design Guide Version 1.1. An ATX12V
power supply has a standard 20-pin ATX main power connector
that must be inserted onto the CN7 connector.
The system board requires a minimum of 250 Watt power sup-
ply to operate. Your system configuration (amount of memory,
add-in cards, peripherals, etc.) may exceed the minimum power
requirement. To ensure that adequate power is provided, use a
300 Watt (or greater) power supply.
