Hi,
I see people asking if 5V power is needed, here is an unedited email reply from KNC from a few weeks ago when I asked them about this :
Hi,
Our devices will require the correct amount of 12V 6 pin or 6 +2 pin PCI-E connectors depending on model, for example Mercury requires 1 PCI-E 6 pin or 6 +2 pin connectors, 2 connectors for Saturn and 4 for Jupiter.
There will also be one 5V connector on each miner for the controller board which will use minimal wattage.
So YES, the miners will require a 5V power in addition of the 12V PCIe connectors.
(and YES, it would be much better for me and a lot of people if they generated the 5V from the 12V; and NO, I don't think it would have been that hard, and I'm an electronic engineer - well, room for improvement in the next gen

)
Hope this helps
