   * Vizy's internal 5V switching power supply can supply up to 6A and operates at 90% efficiency.  The 5V supply is used to power the Raspberry Pi, the [[wiki:pinouts|5V output]], and the USB ports.  The sum of all these currents should not exceed 6A.
   * The power input connector is reverse-polarity protected.

   * The USB-C cable should have a high current capacity.
   * When using a 5V supply, the [[wiki:pinouts|12V output]] won't be available and should not be used.

   * You can still do a safe shut-down of Vizy by holding the button until the Raspberry Pi shuts down, indicated by the beep. You can then unplug the 5V supply from the USB-C port.
   * All other aspects of Vizy will function normally.

-You can also power Vizy through the I/O connector, which can be convenient since the [[wiki:pinouts|I/O connector]] terminal blocks are easy to use.  The disadvantage is that you lose the [[wiki:pinouts|12V output]] for the time being (the 12V output is designed to also be a power input.)  To power Vizy through the [[wiki:pinouts|I/O connector]] hook the negative side of the supply to one of the Ground pins (pin 1 or 8) and the positive side to the 12V output (pin 2).  The same conditions apply to this method as apply to powering Vizy through the power input connector, including reverse-polarity protection.
