 ### 2. Power supply
 
-The Jetson Orin Baseboard can be powered with a benchtop PSU or AC/DC wall adapter providing DC voltage in the 9-15 VDC range with at least 30W.
-For starters, it is recommended to power the board via a DC locking connector (`J12`) which accepts a 2-wire Molex Nano-Fit plug.
-You can use an off-the-shelf Nano-Fit Cable assembly (Molex/[451300203](https://www.molex.com/en-us/products/part-detail/451300203)) or build a custom one from a Nano-Fit receptacle (Molex/[1053071202](https://www.molex.com/en-us/products/part-detail/1053071202)) and pre-crimped wires (Molex/[797582130](https://www.molex.com/en-us/products/part-detail/797582130)). 
-You can also power the board via an RJ45 (`J6`) Ethernet connector using a PoE injector or a PoE-capable Ethernet switch compliant with the IEEE 802.3bt standard and offering at least 40W of power budget.
+The Jetson Orin Baseboard supports three power supply scenarios: 
+
+* USB-C port (`J4`) with charger supporting Power Delivery (PD) negotiation.
+  That is the easiest and most recommended solution for starters.
+  The boards produced and distributed by [CircuitHub](antmicro-hardware.circuithub.com) come with pre-configured on-board USB-C Power Delivery controller which enables power sink mode on `USB-C 0` port.
+  If you have built the board from scratch, you need to [configure the USB-C Power Delivery controller](board_overview.md#configuring-the-usb-c-power-delivery-controller) as described in the Board Overview section.
+  You can use a typical smartphone or laptop USB-C charger rated for at least 45W.
