Powering NVIDIA Jetson AGX Orin using custom SMPS / Battery (without default adapter)

Hi everyone,

I am working with the NVIDIA Jetson AGX Orin and I want to power it using my own power source instead of the default power adapter.

I understand that the board requires approximately 19V DC input, and I am planning to use either:

  • a custom SMPS, or

  • a battery with a DC-DC converter

However, I am a bit confused about the correct way to make the physical connection.

My questions are:

  1. Is it safe to power the Jetson AGX Orin directly through a 19V regulated supply (SMPS or converter)?

  2. What is the recommended way to connect the power — should I use the DC barrel jack, or is there a better alternative?

  3. What is the correct polarity and barrel jack specification (size/type)?

  4. Are there any precautions I should take regarding current rating, grounding, or noise?

If anyone has done a similar setup, a wiring diagram or practical guidance would be really helpful.

Thanks in advance!

Hello,

Thanks for visiting the NVIDIA Developer Forums.
To ensure better visibility and support, I’ve moved your post to the Jetson category where it’s more appropriate

That should be ok, if it can handle ~5A load.

The Jetson AGX Orin Dev Kit supports the DC barrel jack or USB-C power adapter. USB-C could be easiest if the adapter can supply 19-20V.

The Jetson AGX Orin Developer Kit Carrier Board Specification has the information:

The jack used on the carrier board is a Wieson Technologies AC0002-0011-001-HH part. This has a center pin that is 2.5 mm in diameter and accepts a barrel plug with an outside diameter of 5.5 mm.
