Found as workaround that I could align the graphs by specifying a column number.
But missing a restriction of label length - or some label abbreviation as the graphs extend deep into the screen for the longest ones.
Maybe "in a distant future in a galaxy far, far away...." o_O
Only NVIDIA knows...
Comparing values of OCCT, HWINFO64, GPU-Z while running OCCT GPU Test (adaptive and standard)
...on nearly idle:
OCCT / HWINFO "GPU Power" and GPU-Z "Board Power" seems nearly identical (slightly different sampling intervals !)
GPU-Z Board Power Draw seems the sum of...
By chance I discovered that I can use HWInfo values in RTSS OSD, obsoleting Afterburner.
But I hadn't luck to move the labels of these graphs to the right side to get the graphs left aligned vertically.
So the graphs start after different length labels in different columns, difficult to survey...
