just curious, but 110v or 240v?? i'm assuming 240v but from your home or do you rent business space?? been crunching numbers lately.. wanted to add a 240v breaker box for my servers and then mining came along.. i'm fine up to 200A - was going to allocate 50A for starters.. keep reminding the wife not to plug the vacuum into room with "all the computer crap".. ups protected, but she just keeps bringing it all down.. the whole breaker thing is too much

I own my own business so I have my farm setup there at my building. Already have 600 amp 3-Phase power to my facility so I just added twin 30A 240v breakers for the farm. Sized each breaker to handle 5 rigs (each with four 280xs). Only running 8 rigs currently. The heat output sucks so im getting quotes for A/C systems. Will need them if we want to expand.
i actually found your pic's.. very nice.. got some nice power toys in there.. very jealous

i can imagine.. the heats getting pretty bad now with cards maxed all day - only a ceiling fan to push some air out.. i really can't add anything meaningful without a small a/c unit in the room and/or ventilation, and more power.. i have 32 sata drives running in 2 servers, 4 systems for tv viewing, switches and the normal crap.. only low-power nvidia cards, 1-2 years old.. no mining investment to date.. $8-$12/day on average - $25.00 yesterday.. have to stop mining on the nvidia cards next month if i want them to last.. they run way too hot..
that's good to know.. i was planning on 2-3 systems per breaker to leave some room, but may just bump that up.. depends on costs and what i find laying around the old man's garage.. thanks for that..
