19) 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:

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.
