I am interested, could you give extra information about the avalon? How much it drains? is 220 GH normal/overclocked?
Also for some reason your link in the OP are broken
At 1500mhz if consumes around 450w, it runs in normal mode i have never turned up the mhz because the power consumption is supposed to skyrocket to the 1000w range then if i do and both run on the same 10amp fuse.
