7. SSI power connectors (24-pin, 8-pin) These connectors connect to an SSI-type 12V power supply. The plugs from the power supply are designed to fit these connectors in only one orientation. Find the proper orientation and push down firmly until the connectors completely fit. In addition to the 24-pin power connector, this motherboard requires that you connect the 8-pin +12V power plug to provide sufficient power to the CPU. 1. Do not forget to connect the 8-pin +12V power plug. Otherwise, the system does not boot up. 2. Make sure that your power supply can provide 8A on the +12V lead and at least 1A on the +5-volt standby lead (+5VSB). The minimum recommended wattage is 300W. The system may become unstable or may not boot up if the power is inadequate. 24-pin Power Connector 8-pin 12V 12V 12V 12V PCH-DL PCH-DL ATX Power Connectors +3 Volts -12 Volts Ground PSON# Ground Ground Ground -5 Volts +5 Volts +5 Volts +5 Volts Ground +3 Volts +3 Volts Ground +5 Volts Ground +5 Volts Ground Power OK +5V Standby +12 Volts +12 Volts +3 Volts GND GND For Power Supply with 20-pin Power Connector GND GND ASUS PCH-DL motherboard 2-27
