klintay, has stated these boards are made by DIPO if so I would think all that is covered, (12v-5v source used and filtered/converted.)

Dunno. I have all Corsair 950tx and up left over from game dev, they have plenty juice single 25/30a 5v rail TX/HX type. 60/80a 12v rail.

Still if this USB board uses 5v off the ATX, for me that is better, as then I can use the 4/6/8 PCIE cables coming off them to run 12v ANT S1's later on.

So I am asking does this hub have its own power regulation ? If so what does it pull 5v or 12v or both ?

Maybe hubs could start using 3.3v rail as those seem to be unused for asic mining.
