This mainboard provides two ATX power connectors, a 24-pin ATX_PWR connector and a 4-pin 

ATX_12V connector.  You must use a power supply that has both of these connectors and 
both connectors must be attached before the system is powered on. These power connectors 

support several power management functions such as the instant power-on function.  The 

connector pins are described below.
