Unfortunately I don't have the tools to measure the power draw directly from the outlet.

But the software reports 30-45W power draw when the systems at max load. However lower-end titles and idle draw hovers between 10W-20W.

It has no HDMI port. Some DP > HDMI adapters do CEC.

If you get the right adapter, I've seen others get HDMI CEC working.

However, quality of life features like sleep/hibernate don't work at all on this system. I've also seen people use an ESP32 to power on the system with a bluetooth controller which is pretty neat especially if you combined that with CEC.

Not at all
