I am currently running an RPI 4b+ for a home server.

I was able to obtain a small PC with an i5 4690 in it. It has a 300W Be Quite! PSU and a Gigabyte GA-H97M MOBO. I would like to move my stuff from the RPI to this machine, as it has much more slots for HDDs.

For the sake of argument lets imagine I plug 4x4TB HDDs and 1 500mb SSD for the OS and run an Ubuntu LTS on it.

How much average electricity usage am I facing per month in kW/h? How much more would it be compared to the RPI which now has an external 1 TB HDD attached to it over USB?

Thanks a lot!

    I5 4690 idle, with all drives spinning (no read/write) at 60-70watts constant. Maybe a little less. I have a i7 4770s and it’s around 75watts idle with 8 drives, half spun down most of the time. Which is roughly 54 kWH.
