I’m using a Jetson Nano Developer Kit B01 with a fresh install of Jetpack 4.4.1. It’s powered through the barrel connector, using a 5.15V, 4A USB power brick. Immediately after displaying the Desktop, a notification appears that says “System throttled due to Over-current.” After acknowledging the…

The issue here is NOT an overcurrent condition. It’s undervoltage. The notification is misleading. I finally got around to put a scope on the barrel jack input and found the cause: Both my microUSB and my barrel jack cable just were too long/low crossection to deliver enough current while staying w…

hello couka, there’s a built-in under voltage and over current protection mechanism. please refer to developer guide, you may check Under Voltage and Over Current Protection session for more details. you may also access TegraX1 Technical Reference Manual from download center, please refer to Ch…

Hello JerryChang, I read through the resources you mentioned. Unfortunately I’m still clueless whether there is something wrong with my unit. Is there a standardized, quantifiable method to verify the performance of the Jetson Nano? Thanks for your help.

I have the same issue, I use an AC adaptor (5V-3A) connected to USB-C (Jetson Nano 2GB) and the notification appears while running an Object detection model so I suppose as @couka said that is an under-voltage problem due to high requirements of the model.

@lrondan95 Thanks for confirming the issue. I can confirm the notification has not reappeared since I started using short (10cm), beefy (1,5mm²) wires and a stable 5.2V power source.

Hi people. I was also having the same problem, in my case, I was using a 5V 5A power supply. With no load, the power supply has 5.2v with a 0.200V decay, when I turn on the card everything works properly without over current or low voltage warnings. But when I test the detectnet program with the …

I was getting the same notification [“System throttled due to Over-current.”] I am wondering if the cables I am using are way to thin (24AWG). These do not seem to have any issues powering the Xavier NX @ 12V. However, at lower volts perhaps the current (Amps) needed is higher. Also, I needed to r…

I am grateful for your support I am using right in the moment a 5 V power supply with a current range of 2,5V. Using those parameters allowed me to use the maximal power (10W) on my new jetson nano without any problem now

I would like a support, I am using a jetson nano together with a camera, lcd screen and 2 sensors, the system is powered by a 5.5v 20A switching source. When running an algorithm the system is not stable, it also generates this error “system throttling due to over current” and the equipment shuts …

Hi fg12,

Please help to open a new topic if it’s still an issue.

Thanks
