18) Power Supply Connectors (20-pin block ATXPWR) (4-pin ATX12V) (6
pin block AUXPWR (optional)
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: Make sure that your ATX 12V power supply (minimum recom-
mended wattage: 230 watts; 300W for a fully-configured system) can supply at
least 20 amperes on the +5-volt lead and at least 720mA on the +5-volt standby
lead (+5VSB). Your system may become unstable/unreliable and may experi-
ence 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.
