This system is headless, and all drives while idle are spun down within Unraid. CPU is at 1% usage.
Saying that I am sure that it is exactly 30 Watts, No. I have not taken my Unit to work to Calibrate it. Maybe I will do that soon and get back to you with a tolerance.
Also for Clarification this watt reading is measured by the APC.
Take care,
