I want to clarify the exact power requirements for the Jetson AGX Orin 64 GB Developer Kit when powering through the DC jack, specifically for running in MAXN mode.
NVIDIA documentation lists a wide input range, but it doesn’t clearly state what voltage is required on the DC jack.
Some posts mention 19 V, others 20 V, some say 12–20 V works, and a few reference 19.5 V as the recommended adapter value.
Before powering devkit, I want to confirm what exact voltage NVIDIA recommends for stable MAXN operation via the DC jack, since using mixed USB-C/DC power seems risky based on my earlier experience.
What DC-jack voltage is recommended for full MAXN mode?

The recommended DC jack voltage for the Jetson AGX Orin 64 GB Developer Kit when running in MAXN mode is not explicitly stated in the provided context. However, based on the information available, we can make an educated guess.
The context mentions that the NVIDIA documentation lists a wide input range, but it doesn’t clearly state the required voltage for the DC jack. Various posts and references suggest different voltages, including 19 V, 20 V, 12-20 V, and 19.5 V.
To determine the recommended voltage, let’s consider the following:
The Jetson AGX Orin Developer Kit is designed to operate within a specific power range. The MAXN mode likely requires a higher power input to maintain stable operation.
The context mentions that using mixed USB-DC power seems risky, which suggests that a stable and dedicated power source is recommended.
The recommended voltage for the DC jack is likely to be within the range of 19-20 V, considering the various references and posts.
Based on these considerations, it is recommended to use a DC jack voltage of 19.5 V for full MAXN mode operation on the Jetson AGX Orin 64 GB Developer Kit. However, it is essential to consult the official NVIDIA documentation or contact their support team for confirmation, as the recommended voltage may be specific to the device or configuration.
In comparison, the recommended DC jack voltage for other Jetson devices may vary. For example, the Jetson Xavier NX series and Jetson AGX Xavier series have a default CAN clock rate of 50 MHz, but the recommended DC jack voltage is not explicitly stated in the provided context.
To summarize, while the exact recommended DC jack voltage for the Jetson AGX Orin 64 GB Developer Kit in MAXN mode is not explicitly stated, 19.5 V is a likely candidate based on various references and considerations. However, it is crucial to consult official NVIDIA documentation or support for confirmation.

According to the Jetson AGX Orin Developer Kit Carrier Board Specification, anything within 7V to 20V is acceptable (page 3). There is no “required” voltage for the DC jack, as long as it’s in spec. Given that NVIDIA has shipped a 20V 4.5A USB-C power supply, using 20V for the DC jack seems like a sensible choice.
Thank you @tinyserval for the link to the Jetson AGX Orin Dev Kit Carrier Board Spec, which includes the spec below for the DC Jack on the Dev Kit. MAXN is supported for the full voltage range but the current would vary based on the voltage used by a given adapter. The Jetson AGX Orin 64GB module itself consumes up to 60W (refer to the data sheet: Log in | NVIDIA Developer).
