the power draw is huge, but there are not that much options left if you want to mine scrypt.
YUP, not saying don't buy it, just hold off but if you want it be prepared you need two psu per miner or one server PSU at 2400 watts per miner to be safe at least one 240 line at 30 amps id go to at least 60 amps for these, the 30 amps should power two and half of these at a huge increases in power.
The way it looks atm you can buy from them and feel safe only time well tell how they deal with the public.
I really wish bit main had come thu with the L1, but i really think Zeus had some thing to do with that. bit main and Zeus at some point were working to gather, I read some place then that was all, no more .
L1 would have put this to shame .
