 +3V3: Please don't use more than 500mA for the +3.3Volt Rail.
 +5V: Please don't use more than 500mA for the +5Volt Rail. The system doesn't use a lot of +5V, but there are spurious needs for +5V rail when an HDD (spinning) is installed in the system.
 +12V: The limit of current you can draw on the +12V is related to the power supply you are using for your machine. It is better to use that power supply to derive any other from.
