Looking for some help with PSU choice for s3, have read a few people talking about running two S3 from one power supply, looking at Corsair 850HX 80 plus silver (£75), Corsair 750HX 80 plus silver and (£66) Evga 750 super nova 80plus bronze (£61). Will these psu run 2 machines ?  any user had experience or thoughts on running two S3 or S1 from these power supply's, Overclocked all my Antminer S1 from day one and none of them have ever missed a beat, reading posts on forum don't think i will overclocking the S3 for now. Currently use Corsair cx600m 80 plus bronze for  miners which cost me about £55 each have eight S3 from batch 4 if i could save £200 by using only 4psu goes a long way to helping with ROI, any help would be appreciated.
