Installing the CPU
The 2808080 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.
