There are three power connectors on this motherboard. By default, this motherboard requires that
you have an ATX12V power supply that has the standard ATX-style 20-pin connector, as well as
an additional 4-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 4-pin square connector and the 4-pin auxiliary drive power connector. The +12V power
on the 20-pin ATX power connector is for system board and separated from CPU +12V regulator
power source. Therefore, the CPU won't be powered neither connecting the 4-pin square ATX
12V power connector nor 4-pin auxiliary power connector.
In addition to the onboard 4-pin square connector for CPU regulator power, the onboard 4-pin
AUX drive power connector provides one addi12V power wire.
