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 power

connector that must be inserted into the 24-pin connector. The 8-pin +12V power

connector enables the delivery of more +12VDC current to the processor’s Volt-

age Regulator Module (VRM).

The power connectors from the power supply unit are designed to ﬁ t the 24-pin

and 8-pin connectors in only one orientation. Make sure to ﬁ nd the proper orien-

tation 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.

Important:

Insufﬁ cient 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.
