Jetson orin nano super system throttled due to over current lowcurrent problem

Currently, when I run a program on the Jetson Orin Nano Super, I get an error that says “system throttled due to over current lowcurrent.”

I have the power settings set to Max.

I’ve confirmed that this error is caused by the adapter’s low power output.

I am currently using a 19V/2.37A rated DC adapter.

To resolve this issue, would it be okay to use an adapter with the same voltage (V) but a slightly higher current (around 5A) (A)?
→ If I use an adapter with this capacity, will there be any issues with the board during use? (It won’t damage the board, right?)

When the Jetson Orin Nano Super is set to Maxn mode, what is the maximum power (W) the board can handle?

Are you using the adapter bundled with the Jetson Orin Nano Super Dev Kit or a different one? The bundled adapter should not have any problems with Orin Nano in MAXN Super mode.

The Jetson Orin Nano Developer Kit Carrier Board Specification shows the max current on the DCJ_IN to be 4.2A. As long as the Dev Kit and module are not damaged, a 19V/5A adapter should be ok. But ideally you could try a 19V/4 to 4.2A supply first.

I’m using Jetson Orin Nano Super Dev Kit with official 19V/2.37A adapter. Running in MAXN_SUPER mode with jetson_clocks applied.

I logged power data while running an AI inference program (YOLO + TensorRT) and found that oc3_event_cnt increases every time VDD_IN current exceeds ~2008mA.

Measured values at throttling moments:

- Voltage: 4944mV (fixed) - Current at trigger: 2008mA ~ 2120mA (avg 2075mA)

  • Power at trigger: ~9.9W ~ 10.5W

  • Total throttling events: 257 times in ~40 seconds

It seems the soctherm oc3 threshold is set to ~2A on the internal 5V rail.

Questions:

1. Is this 2A limit a hardware-fixed value in the SoC, or can it be adjusted via BPMP device tree?

2. Will replacing the adapter with 19V/4A resolve this issue, or is the limit internal regardless of adapter capacity?

3. Is this expected behavior for MAXN_SUPER mode on the official Dev Kit?

JetPack version: R36.5.0 (January 2026)

Please do not run with MAXN mode. This mode is not something for you to do long term test.
Hitting OC in this mode is totally expected.
