3.8 – Installing the Power Supply
There are two power connectors on this motherboard. By default, this motherboard requires
that you have an EPS ATX12V power supply that has the standard ATX -sty l e 24-p i n
connector, as well as an additional 8 -pin square connector. The CPU power is provided by the
onboard switching voltage regulator, which is sourced by +12V power. This +12V CPU power
source is from the onboard 8- pin split power planes. The +12V power on the 24- pin ATX
power connector is for system board and separated from CPU +12V regulator power source.
Therefore, the CPU will not be powered if you do not connect the 8- pin CPU power connector.
PW1: 2 4-pin main power connector
PW2: 8pin +12V power connector
NOTE
YOU MUST
unplug the power supply before plugging in t h e 2 4- pin and 8- pin
power cables to motherboard connectors.
