Anyone know the power requirements for the Neptunes? I have some coming in and i want to buy some power supplies before hand. i can't really ask for a refund as i have others depending on me making bitcoins for them.

There is only speculation at this point as KnC has not released any final details yet. But it's likely going to require you to run your Neptune inside a co-location as you will likely need two to four 20AMP circuits to power one. In co-lo's you pay per circuit and not pay for the consumption of power.

What 40A to 80A at 230V to power one Neptune I don't think so. Even 40A@110V sounds far too high as Bitmine can get ~1(GH/s)/~1W@28nm at the wall socket.

Going by KnC's old numbers it was speculated you would need about 3500 watts to power a 4TH/s machine, if KnC bumped it up that high. At this point it's hard to say what the new number means, 43% less power, is that less than original predicted or less than what the 28nm wafer, or chip? So instead of being 0.7watts per GH, I guess its 0.57 watts per GH?

Using the new numbers, I would speculated that you will need 600 to 700 watts of power per 1TH/s. Regardless though I will be sticking my Neptune into a co-lo this way I don't have to worry about the added costs involved in cooling it and I will also able to run it on cleaner power, 200V.

+1 Well spotted. I was wondering what that % was based on too, 43% less power consumption of something that doesn't exist doesn't make sense really does it? Meaningless number without something to compare it from.

This is so much more fun without any money in Swedish hands to worry about I have to say.
I wish you good fortune come summer. You're braver than I. lol
