3. HARDWARE SETUP
11) Power Supply Connectors
These connectors connect to an ATX 12V power supply. Each plug from the
power supply will only insert in one orientation because of the different hole
sizes. Find the proper orientation and push down firmly making sure that 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.
