My apologizes for silly question.
I ordered 26 antminers S3 and they are almost here.
How do I set up my mining rig?
What do I need except PSUs?
Thanks in advance!
Do you even have the available power to drive all of them? At 340W each from the wall, you're looking at 8840W minimum available power - or at least 2 220V/30A circuits. Not to mention, you'll need enough network switches, cabling, cooling, to handle them all.
OP, I hope you are not trying to run them in your home, as not many residential house can provide that much power and you need further more electricity for your other electrical appliances.
These miners will also emit lots of heat and so you should monitor the room temp closely to see if you need better cooling or air-conditioning.
