I have the same problem with rtx 2080 super.
Windows 10 21H1 10.0.19043.
I have driver type: DCH
In HWiNFO there is no wattage report.
Usage of old drivers for long term is problematic.
Have you found solution to this?
Thank you for reply. There is HWiNFO debug file.This could be a driver issue, please attach the HWiNFO Debug File.
Thank you for helping with my problem. I am trying to fix nvidia driver,I analyzed the raw data and can confirm that this is a driver-related issue. NVIDIA has removed reporting of all power-related information in the driver.
I don't know why they did this, perhaps reinstalling the driver or downgrading to an older version might work.
