Hi,
If you select one of these miners and look at the bottom part of the screen, you will see the GPU tab. On the GPU tab you will all GPU's listed for the selected miners. For each of the GPU's you will also see the power usage.

By comparing this list of GPU's between your two miners it should be possible to find out the power usage reported for each GPU. You can also see if the "Map to system monitoring" is enabled.

Can you please share two screenshots from the GPU tab, one for each of these two miners that are idential? Thanks!
