18) ATX Power Supply Connector (20-pin block ATXPWR, 6-pin EAUXPWER,
4-pin ATX12V)
These connectors supply power from ATX and auxillary power supplies. Each
type of connector socket requires a special plug from its type of power supply.
Care must be exercised to sellect the appropriate connector for each power source.
See the specifications for each power source below. When plugging the
connectors, push down firmly to make sure that the pins are aligned.
Important Specifications: The minimum requirement for full-power loading is
a 400 Watt ATX 12V power supply; minimum requirement for +5v/3.3.V is 180
Watts; +12 Volts requires 15 Amps; 5VSB requires 1 Amp. Also ensure that the
ATX power supply can put out at least 10mA on the +5-volt standby lead (+5VSB).
You may experience difficulty powering ON the system if the power supply
cannot support the load. For Wake-On-LAN support, your ATX power supply
must supply at least 720mA +5VSB.
NOTE: It is recommended that both ATX power connectors be supplied to achieve
adequate power.
