How much electricity would this build cost? (alien.top)

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!

Would guestimate the PC (with no GPU) to pull maybe 100w assuming an average load of 20 ish percent. - 40 of this would come from drives (about 10w each).

This would be about 2.4kwh/day or in the UK, around £0.70 on a cheap tariff (or £255 a year). Obviously these figures vary massively depending on power cost per kwh in your region
