Hi
Is there any more information about power requirements?
If these (and other boards) sell well, there could be a problem buying power supplies of the right quality and size.
We may need to pre-order psu's to obtain the best units.
BFL seem to have had problems along these lines.

These boards use standard 6 pin pci-e connectors, like what you use with a high end gpu
I do not know the exact power requirements per board yet , but it can easily be measured after form assembles the first board using these new rev 1.2 boards.
The datasheet for the chip is here: http://my.root4u.de/BFL_SHA2_Spec_Rev2.2.pdf
Which may be helpful,
But honestly I would just buy a high end certified gold or certified platinum "gaming level" psu
1000w-1200w Seasonic Platinum or Corsair Gold/Platinum Something like that
I actually tested several BFL 50Ghs SC's (they actually do 65Gh/s+) which I believe have 16 chips in them, and I was able to easily run 3 Units from one 1200w Seasonic Platinum PSU. It had enough connectors and plenty of power. So I would imagine the contamination board will use about the same amount of power as the BFL 50 SC here: https://products.butterflylabs.com/homepage/50-gh-s-bitcoin-miner.html
Hope I was able to help.

FYI,
Mini rigs are shipped with two 1500W power supplies. One running 4 singles (64 chips) pulls 950W from the wall, the other is running 4 singles (64 chips) plus all the sidewall fans, pulls 1100W from the wall.
