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.
