2.1.2 Power Requirements
The MITX-CORE-820 is designed to receive power from an input power connector that accepts
+12V or +14.4V~+19.5V in the back-panel IO region, or from a 4-pin +12V ATX power
connector. When a charger board is used, the power can be supplied using a 4-pin +12 V ATX
power connector from the adapter or battery connected to charger board. The TDP of the
board is 70W (no peripheral). The maximum power consumption of the board is 180W (with
the following assumptions: 75W PCI Express Graphics card, all of the USB ports are active or
powered, all components and peripherals on the boards are running at full loading). The power
supply used for MITX-CORE-820 should have margin to meet the power consumption in
different circumstance.
When the back-panel IO power connector is used to power the board, the 4-pin +12V ATX
power connector can also be used as an output DC source, but assuming this wouldn't affect
the power of the board.
2.1.3 Power Dissipation
The following table shows the power dissipation of the board’s critical components.
