Sure
but what I calculated... I have to buy psu's for the sp20's and to have the same power than a sp35 , it would cost me pretty much more than buying sp35's and I would need approximately 3 sp20's to equal one sp35. So more outlets and space..:/ anyways I guess it won't cost a fortune to modify stuff... And I guess to be on the safe side it would be only one machine per outlet. I will get in touch with my electrician soon and give some feedback here if anyone needs help on approximate prices for parts etc...
Its always a toss up over what to buy. If the SP35 goes down your 100% down, if 1 SP20 of your 3 goes down, your only down 33%. Most here have been thru a lot of upgrading of equipment and we just sell off the older stuff but keep the PSU's to use on the newer stuff. So I like buying good quality PSU's and am still using the same one I had used on my BFL 60GH Single, then on my S1 and then S3 and now use it on my S5 miner.
