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 this connector.

Your power supply unit may come with an 8-pin or 4-pin +12V power connector.
The +12V power enables the delivery of more +12VDC current to the processor’s
Voltage Regulator Module (VRM). If available, it is preferable to use the 8-pin
power; otherwise connect a 4-pin power to this connector.
