Anyone out there with 4+ rigs? how are you powering them? I can't seem to find enough breakers to split the load...
Are you guys at the point of renting space/power? Data center?
I have 12 rigs in my house, each with 3-4 cards (with the exception of 2 of them only having 2). Each of my 20 amp circuits have 2 rigs hooked up. Some of these rigs are in an upstairs room where I had an electrician put in a small sub-panel. There are two rigs that are just in spare bedrooms hooked up to a normal 15 amp circuit each having just two cards.
The subpanel takes up two slots on the main panel, but it is using a much higher fuse - 50 amps I think. I am completely out of spaces. If I had more power and ways to cool them I would put in more rigs.
I have been mining since April of 2013 and am in for $42,000 including hardware and electricity (and a couple of Monarch preorders).
and how was your ROI so far? I'm planning to do the same. I don't believe that crypto mining is dead. I only have 2 rigs right now but i already bought and stacked a couple of r9 280x in my spare room. Just waiting for the powered risers that i ordered in the U.S so i can continue working on my rigs. And i am doing the same as you. I hired an electrician to make a 30 amp circuit for a specific room as sub to my main circuit which is 60 amp. Btw, in my country the standard line is 220V.
