Great eye.  You [both] win three internets and a kitty.  Amazing.

Serious congrats for being the first to take the extra step.  I'm amazed that it took almost 2 pages of people pissing in the wind to do a simple image search.

I don't give a damn about CE markings since I live in the U.S. But, I was under the impression that BFL is still having rigs seized in EU customs for both the CE markings and missing owners manual in the proper language. Just hoping KNC is way out in front of this. Then again, releasing the manual will probably spill the beans on a lot of 'insider info' they don't want public yet.

Yup, the Coolermaster V1000 I bought for my Jupiter has a graph on the back side with their claimed efficiency, which goes from 90% (100% load) to about 93% (50% load) to 92% (20% load) efficiency.

However, there is also a graph for the fan speed which goes from about 1200 RPM at 75% load to about 2300 RPM at 100% load. So there it might matter.

If I read Wikipedia correctly, they can basically slap that marking on their device by themselves. Also they're targeting businesses, I don't know how much that impacts the need for certifications.

That hasn't been true for the last decade but it is a myth which dies hard.

The minimum efficiency for an 80-Gold PSU is 90% at 50% load and 87% at 100% load.  The curve is very flat.

For example here is the test for the PSU linked to:
http://www.plugloadsolutions.com/psu_reports/CORSAIR_CMPSU-850HX_ECOS%201464_850W_Report.pdf

50% load = 90.38% efficiency
75% load = ~90.0% efficiency (estimated due to their horribly low res chart)
100% load = 87.06% efficiency

So using a larger PSU would save you maybe 1% in power, 3% under the extreme example of 100% load vs 50% load.  At 1% power on 600W 24/7 would save you 53 kWh per year.  At $0.10 per kWh we are talking $5.  Spending $50 more on a PSU makes the break even 10+ years. At once time PSU were pretty shitty with narrow "sweet spot" (40% to 60% of peak power), and efficiency tanked (<70%) outside of that.  This is where the advice of buy 2x the needed power.  Those days are long gone thanks to the 80 Plus program and even lower end 80Plus PSU have an almost flat efficiency "curve" for loads anywhere from 20% to 100%.  It is nice companies keep making more and more efficient PSU (Platinum and Titanium are also possible) but once you get to ~90% it starts being diminishing returns.    Still Google and facebook use custom PSU which only output 12V to get 95%+ efficiency.  Really there is no reason for PC PSU to be as complex as they are.  Maybe some future standard will improve that.  

You know what I wanna see? An owners manual and CE certification. They have to have them in order to meet customs, right? Give us some owners manual pdf love, fellas!

Anyone know if these heatsinks can be rotated at all?  From the picture it looks like there is a mounting screw at the front to the board (and I' assuming the back as well) but none on the side.

The way I see it, they took the open source CGMiner code as a starting point and developed their own version. It is not really "CGMiner" anymore.  It is more like "KNCMiner based on CGMiner".  It is a fork of CGMiner and both forks will go in different directions over time. KNC will have to update their version from this point forward.

You could be right, here's a comparison:

Also note the round edges.

... I think he is trying to infer that they may have used a rPi as the embedded linux... and as for the re-flashing / programming, this is totally incorrect, Raspberry pi's run a standard ARM build of linux off of an integrated SSD card. There would be very little retooling involved with these little guys, the units themselves have both integrated USB as well as capacity to feed and poll information via GPIO interface.

I for one would have no problem with them using rpi's for the embedded linux platform. They're a solid choice

I see a custom case in my near future!

It's stand alone. USB would be pointless. Provide power and an internet feed, that's all it needs.

Anyone know what they are doing as far as working with cgminer or bfgminer.. it seems that they are writing some middle open source communication layer for cgminer.. but what if cgminer changes things, will KNC always have to update this open source miner or does it now become the job of cg and bfg to make changes .. also is this a good idea to do this? I mean they claim a 30% increase using their in-between layer but well..

anyone have any ideas or more incite.

I thought they planned on putting a usb port on this thing?  or am i just blind and not seeing it?

I don't even have an order with them, but they do have my mining info. Hahaha

Should be the minimum acceptable wattage for a power supply.  I'd recommend going with something around 1kw... They are much more efficient at 50 % load versus 80 - 90 % load.

did you guys forget to provide your mining pool info..  at the least, we will start to get some coins to let us know they are close to shipping

Alright guys, some of you have a lot more knowledge then me in the PSU area, so if you could help me out here, I'd appreciate it.
I have a Saturn on order, which I plan to upgrade to Jupiter once they start offering the modules separately. The PSU that I have picked out seems like a perfect fit to me, and at a fairly good price. If you guys could look it over and let me know, that would be great. And if it is a good one, it could turn out to be a good deal for everyone.
