all in all im predicting 2kw after i bring my quad gpu box + file server online, and counting the rig im running at a friends house. right now its 1350w. at aprox $0.50/KWhr its $4380 a year once i bring the 4th rig online, but lucky me i dont pay for any of it lol. 3 rigs that are at home are on my step dad's bill, and he works in IP lit, makes more in an hour than my personal monthly power bill, and the 4th rig accounting for the last 300w is run at a friends house since it's his actually his. i built it for him 2/3 on my dime and he runs seti and collatz until he pays me back in full . california is not a good state to be in if you're a cruncher LOL. if i keep living here at these rates im either gonna have to go all solar on my farm or pay a friend to run my boxes out of state D:
