It's very pessimistic, it takes into account the compunded exponential rise in hashrate, rather than a fixed rate over time, that's why it's become popular. It's not accurate though, nothing can be unless it can foresee the Bitcoin SP, and related price fluctuations.

Also it bases prices of kit bought in November and beyond on what details we have now. Miners won't be selling for those prices come Jan. They will have to be priced more competitively.

Crucially for KnC buyers is what happens between Sept and Jan and how quick we can plug in units configured to wallets, which is also out of out hands currently...

Yes but the SP isn't fixed, is it? Although we can assume within a standard deviation there is some accuracy without a significant newsworthy change occurring to impact it either positively, or negatively.

Sorry you use it in trading, it means 'stock price', or 'sale price'. I was referring to the BTC/USD exchange price.

Your specs simply don't match what was given, and the modules are sold under many names.

What's SP?

Kindly draw your attention to what KNC just told you...

What do you mean? Isn't the rise exponential?

If you will kindly draw your attention to the footer of each page of the datasheet.

Not sure what the relevance of a part made by lineage?  Didn't KNC state the power supply used in from GE Critical Power?

Is http://mining.thegenesisblock.com/ the best calc to use at this point?  I see a bunch of them out there and this seems to be the only one that is either very accurate or is the least favorable.

No.  Of all the risks this isn't one.  Total annual bitcoin revenue is a rounding error for a company like Samsung or Intel.  In theory (and I am not saying it is likely) some years or decades from now when Bitcoin is many magnitudes larger it might attract the interest of a major semiconductor company however by then the Bitcoin ASIC companies who have survived will have years of experience.  A big player would simply buy the company outright to hit the ground running. 

Just buy bitcoins then. Or buy from a company that has stock in hand already, like bitfury. If you want to take a risk and invest into a pre-order I would suggest going with KnC. Also make sure you check out http://mining.thegenesisblock.com/

What is going to happen, people like Intel and Samsung coming in and crushing all the small time players? 

hh, what you want to hear?.)

Answers? Only 15 bucks upfront!

And did you see that ripple voltage? !!!
Oh my gosh, between 8-20mVp-p at 1 volt!

It's too bad they couldn't use 2 of them at once.
It's too bad they don't have a SYNC function.
It's too bad the SYNC function couldn't be programmed to reduce ripple by interleaving.

If only there were such things.

Oh wait.....
They do have those functions.

Gee I wonder if the KnC guys noticed or it was just coinkydink

It's too bad the pdf you linked didn't include examples of how to deal with the known limitations.
Oh wait.....

All DC/DC converters have limitations.
The efficiency is not bad. It's 80+ and that's DC/DC at 1/12th supply V.

An engineer could design better given enough time and money.

But (there's always a 'but')

Not if you wanted off the shelf _and_ wanted some headroom within the $$$/time budget.
IMneverHO

25% of possible total supply voltage range for the device seems quite flexible to me.
They have V to spare if their thermal budget has any room left.

I almost forgot.
"And the whopper, 1.5ms typical rise in output current from 10% to 90%."

It's too bad they couldn't place caps around the ASIC to compensate.
Oh wait.....

Are you some kind of inductorologist with mad skillz?
I didn't notice your suggestion for a better choice.
Please include delivery time and cost savings if you do venture an opinion.

To me their DC/DC supply fits exactly their 'margin on top of margin' claim.
Thx for the link!

Time will tell
