1-18 Chapter 1: Product introduction
4. ATX power connector (20-pin ATXPWR)
This connects the power plug from the power supply. The power supply plug is
designed to fit this connector in only one orientation. Find the proper
orientation and push down firmly until the connector completely fits.
If you will need to replace the power supply in the future, make sure that your
new ATX 12V power supply can provide 8A on the +12V lead and at least 1A on
the +5-volt standby lead (+5VSB). The minimum recommended wattage is
230W, or 300W for a fully configured system. The system may become unstable
and may experience difficulty powering up if the power supply is inadequate.
