GTX 650 nvidia NVML power usage unsupported

Hi all,

I wanted to get power usage via NVML for GTX 650,but it showed unsupported when I used the function nvmlDeviceGetPowerUsage.

I checked that GTX 650 is based on Kepler architecture. According to NVML reference manual, the power management mode is supported. So getting power usage should be available. I also tried to use nvidia-smi command, again it was unsupported.

Does anyone know what happened?

BTW, GTX 650 is on another machine and I login to that machine through ‘SSH’. Is this the reason?

Thank you
