20) Power Supply Connectors (20-pin block ATXPWR) (4-pin ATX12V)
These connectors supply ATX 12V power. Each power supply plug inserts in
one orientation only. Push down firmly and make sure the pins are aligned.
IMPORTANT: For typical system configurations, an ATX12V power supply
that can supply at least 230W and at least 8.5A on the +12V lead is required. For
heavily-loaded configurations, an ATX12V power supply that can supply at least
300W is required. Your system may become unstable/unreliable and may expe-
rience difficulty in powering up if your power supply is inadequate. For Wake-
On-LAN support, your ATX power supply (minimum recommended wattage:
230watts) must supply at least 720mA +5VSB.
