What are you doing with those 4 computers that you run 650 watts each? Playing videogames on max with dual video cards??
private servers made of not the best parts, 1 is for 3d rendering projects (easy side money...classmates send me the 3d file and then i render it out ), 2 are game servers running, and last 1 is just clone of the game servers
like i said not the best parts like 7-10 years old and pawn store quality
Avalon 6 has a group buy it looks like currently that might be worth looking at if stuck on 110/120. But your right if they are able to power the S7 it is cheaper as far as hash currently.
I think he needs to figure out the wattage like you said though. Unless his line is 220/240 I think one modern miner will use most of his "2 power outlets but are on the same power line"
sry about that
i have standard 110/120 with rare power spikes
