Hardware Installation
Power Connectors
Use a power supply that complies with the ATX12V Power Supply Design Guide
Version 1.1. An ATX12V power supply unit has a standard 24-pin ATX main pow-
er connector that must be inserted into the 24-pin connector.
The power connector from the power supply unit are designed to fi t the 24-pin
connector in only one orientation. Make sure to fi nd the proper orientation before
plugging the connectors.
The system board requires a minimum of 300 Watt power supply to operate. Your
system confi guration (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 recommend that you use a minimum of 400 Watt
(or greater) power supply.
