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!
find an online calculator used for determining a UPS size (google will help).
That will give you an indication on how power the system will use.
then calculate based on your electricity price (thin there are online calculators that will do that as well).
