Installing the CPU

The MI941 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.
