so 4500gh at 3000 watts

okay that is .666 watts a hash .

my s-3's do 430 gh at 328 watts that is  .763 watts a hash.


lets see some paid 4500 usd some paid 5000 usd.

for 4570 usd I  get   7.8  btc that is 12 s-3's .

I need  4 psu's  to run 12  s-3's

4 evga's 1300 = 680

so I need 5250 usd for 12 x 440 gh = 5280 gh and 3936 watts - s-3's

5000 usd for 1x 4.5th and  and 3000 watts = s-3

while it is sad that the sp30 is short. it is close to equal to buying s-3.s .  

maybe just a bit better if you paid 4500 and get the sp30 before the 2nd of aug.
