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.
4. USB header (10-1 pin USB56)
If the USB ports on the rear panel are inadequate, a USB header is available
for additional two USB ports. Connect one end of the USB port module cable
to this connector, then mount the USB module to an open slot in the chassis.
