Jetson nano power led blinking


Iam training ssd mobilenet on jetson nano,
When the training starts the power led (green led) starts blinking and i get a notification (system throttled due to over current)
Iam powering my nano through a 5v 20A computer power supply through the barrel jack.

Any idea why this is happening?
Thank you

The led blinking indicates over current issue, which is monitored by internal power monitors to keep system in safe. Please refer to this topic too: Power LED blinking meaning?
