Even a small setup ie 4x 3070s uses 590w (if setup right) and hour thats 14.16kw a day. Only makes about us$20 a day most days sometime 27 if really lucky.
So you could maybe just run that. But atm its very expensive to get into mining. If you dont have spare gear already then I doubt you will get any decent ROI.
Even using less gpu say 3x3070s well u still have to power cpu, mobo and ram so it only takes about 135w off not 1/4. So the earning is a bit less then 3/4 then.
Maybe this helps idk.
