Get voltage and detailed power data via NVAPI

Hi all,

Does anyone know which of the NVAPI function provides access to the detailed voltage and power data like GPU-Z shows it (namely the power readings for the different shunts “8-Pin #X Power”, “PCIe Slot Power”)? I know how to get the total board power via NvAPI_GPU_ClientRegisterForPowerSampleUpdates, but I could not find APIs for the individual power rails, yet I assume that GPU-Z gets it from NVAPI, because I can see using procmon that they are loading the library when showing the sensors.

Best regards,
Christoph
