INSTALLATIONS
Installing the CPU
The MI940 motherboard supports an LGA 775 processor socket for Intel® Core 2 Duo processors.
The LGA 775 processor socket comes with a lever to secure the processor. Refer to the pictures below, from left to right, on how to place the processor into the CPU socket. Please note that the cover of the
LGA775 socket must always be installed during transport to avoid damage to the socket.
ATX Power Installation
The system power is provided to the motherboard with the ATX2 and ATX1 power connectors. ATX2 is a 24-pin power connector and ATX1 is a 4-pin 12V power connector.
The 24-pin power connector can to be connected to a standard 20-pin ATX power connector in a standard ATX power supply (Min. 400watt).
Note: The power supply 5VSB voltage must be at least 2A.
