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.  

J26: 24 pin EPS 12V power connector 

J37: 8 pin EPS 12V power connector 

Note 

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.
