I agree absolutely about the almost total lack of actual power
consumption figures for PCs.  It took me a long, long time to find
some useful figures.  I did find something in the end though, it's a
spreadsheet from 'EU Energy Star', the one I have is a few years old
but it covers systems up to four or five years ago so is ideal for
refurbished systems like the Esprimo ones above.  (That should be Q556
not Q557 by the way).
 
The file name of the actual spreadsheet I have is:-
 
    eu_energy_star_computers_61_-_20180220.xlsx
 
I think searching for that name should get you somewhere, but if not
then drop me an E-Mail (valid address here) and I'll send you a copy.

Oh, that's super useful:

For those wondering (I had to look it up):

Short-idle mode means a state where the computer has reached an idle condition five minutes after operating
system boot, after completing an active workload, or after resuming from computer sleep mode, and the primary
computer display is on and the computer remains in the working mode ACPI G0 (S0)

Long-idle mode means a state where the computer has reached an idle condition 15 minutes after operating system
boot, after completing an active workload, or after resuming from computer sleep mode, and the primary computer
display has entered a low-power state where screen contents cannot be observed (for example, backlight has been
turned off) but remains in the working mode ACPI G0.
