I can't find the thread, but I believe I've seen someone from NVIDIA mention that 4.8A was way overkill, and they would be refining the requirements later. On my bench setup, I haven't seen the Jetson draw more than 1.5 amps at 12V, and this was during testing of low voltage conditions on the regulator.

The kind folks at elinux.org have benchmarked power consumption for various tasks, looks like nothing draws more than 12 watts of power: http://elinux.org/Jetson/Computer_Vi...r_vision_tasks

If you have additional peripherals, that may raise your power budget, but I'm comfortable running it off of the 12V regulated supply.
