2.11 – Installing the Power Supply
There are two 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. 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 will not be powered if you do not connect the 4-pin square ATX 12V power
connector.
Unplug the power supply before plugging in the 24-pin and 8-pin
power cables to motherboard.
2.12 – Finishing Up
Congratulations on making it this far! You're finished setting up the hardware aspect of your
computer. Before closing up your chassis, make sure that all cables and wires are connected
properly, especially IDE cables and most importantly, jumpers. You may have difficulty
powering on your system if the motherboard jumpers are not set correctly.
In the rare circumstance that you have experienced difficulty, you can find help by asking your
vendor for assistance. If they are not available for assistance, please find setup information
and documentation online at our website or by calling your vendor's support line.
