So i 've had fun with the u1's I bought from a us supplier how much more complex are the s1's. If I order the miner does it need a seperate power source I think I read this somewhere, and does the power source have to be custom built? Thanks for the replies guys!
You can use an ordinary computer PSU, with some care in selection for one that provides enough power on the pcie power connectors. Beyond that, they're basically self contained— a little embedded mips computer running linux and an ethernet port.
So a 450 w PSU with two pcie connectors should be sufficient , considering bitmain's 360 watts a the wall statement, and do I need to understand the 3 +12 v DC input statement or will the two pcie's sort all this out?
