I was recently given a nahelm Mac Pro that i was going to setup as a html / dreamweaver / photoshop workstation. As i was preparing the computer, i got to thinking; should i even use this energy hog or just go out and buy an entry level m1 mac mini? Obviously the power usage between these two computers is significantly different but does anyone know how to accurately prove this theory? I have an old kilowatt meter but I’ve never researched how to use the numbers I get off the readings. Watts and amps all look wildly different between the two but how do i translate that into what i will actually be charged/savings on my energy bill? Just looking for real world/ tangible numbers to make sure i am not just falling back into old habits of tech lust.
