Just wanted to note that I am selling a few of my pre-orders if anyone is interested:

Ok, thanks all.
I think the conclusion here is that each 6+2 or 8 pin PCI-E connector (150W) coming from the power supply can easily be split into 2x 6 PIN PCIE connectors, which means that each 6+2 PCI-E connector can power 2 K16 boards. Each K16 board only uses ~32W before overclocking, so there should also be some headroom left to overclock.
With that said though, there will be 1 PCI-E, 6 pin connector on the k-16 board. We can plug a 6 pin in to it ( just like a graphics card )....but it will only draw 32 watts of the 75 available watts supplied via the 6 pin.... in other words it won't shove more 32 watts into the board or will pull as many as needed if OC'd etc...but then not much more than the 32 maybe 40 tops??? good topic in here...I think the conclusion here is that each 6+2 or 8 pin PCI-E connector (150W) coming from the power supply can easily be split into 2x 6 PIN PCIE connectors, which means that each 6+2 PCI-E connector can power 2 K16 boards.

PS: I was clarifying for myself as much as anyone else! lol.... There has been a lot of questions to come up lately with i2c pins, pci-e ,,what comes with the boards etc....so this is all good... Now on to the k 64 power questions,,,lol

The amount of power that is actually available is defined by the power supply, specifically the 12V rail you are using.
I think this is it. Having the available power capacity / rails on your psu might be more important There are all sorts of adapters available that don't make much sense. For example, it's easy to find 6 pin to 2x6 or 2x8 pin PCIE splitters, which can't possibly provide enough wattage to each PCIE connector.
Basically, will a 8 pin to 2x6 pin splitter provide 37.5W or 75W to each 6 pin PCIE connector?
Note that in the picture of the adapter, you can clearly see that only 6 of the 8 pins in the 8 pin PCIE connector are used to split to 2x 6 PIN connectors. 2 of the 8 pins in the 8 pin PCIE connector are not used for anything.

because the extra 2 for and 8pin are just grounds, not adding to capacity per se, but maybe adding to stability... and here are some people saying 6 pins go over 75w

maybe we are overthinking this one?
I know I am pulling way more than 150w on my 7950's, which only use 2x 6 pin. I'm a bit confused about how 8 pin PCIE to 6 pin PCIE splitters work. 8 pin PCI-E devices can provide up to 150W, but a 6 pin PCI-E device can only provide 75W. I also understand that if you use 6 of the 8 pins on a 8 pin PCI-E device, it only supplies 75W in order to be backward compatible (i.e. you need to use all 8 pins to get 150W).
If you use a splitter to go from a 8 pin to 2x 6 pin PCI-E device, does each 6 pin device get 75W or 37.5W? I suppose that it may depend on how the PCI-E splitter is wired and whether or not it uses all 8 PCI-E pins.

I am no EE, but I would guess that the power lead will only provide as much power as the device will draw. IE 6 pin provides up to 75w, so if you plug in only 1x k16 it only provides the 32w that the device is asking for. So, if you had a 8 pin to 6 pin adapter, each 6 pin could still provide up to 75w because your 8 pin provides 150w. The idea for these is that you could then take the 6 pins you get from that adapter and add splitters to them in order to power up to 4 k16s (128w) off that one 8 pin.
Someone correct me if I'm being stupid, but that's what makes sense to me
EDIT- I suppose you're right in that it would matter how the 8pin to 6 pins are wired, but it only makes sense to give it all 150, who wants a 37.5w 6pin??

If your PC has an 8-pin PCI-E power cable, the power supply can be assumed to be able to provide 150W of power to that cable. If you split it with a 6-pin to 2x6-pin splitter, you may get less than 75W supplied at each split because of the two unused grounds, but you should still certainly get a good deal more than just 37.5W per split.

where as the 6 + 2 pins start at 75 watts,,, but connect the 2 extra pins it now supply's 150 watts....I think we're worrying to much but needs discussed for sure.

Already confusing enough...my psu has a 6+2 pins pci-e. I guess thats same as 8 pins which provides 150w?. If that's the case one 8 pins should be enough to power a K64 (32w x 4) with 3 pci-e splitter (tri-y setup).

Unless this info is in here somewhere and I missed it?
You can see the DX large has 3 case fans on it, so you shouldn't need very much air movement for a single k64
Starting to get my setup ready, so I have a bunch of (dumb) questions:
- K64 needs 4 or 1 pci-e power plug?
Looks like 4. See https://bitcointalk.org/index.php?topic=239377.new However, one pci lead from the psu with 2x 6 pin connectors will give a total of 150w (75w for each 6pin), so you could probably use splitters to get 4 pcie connections and power it that way. the k64 needs 128w- K64 needs 4 or 1 pci-e power plug?

- K64 comes with 4 or 1 heatsink?
I would assume 4 from seeing the k16 hashing video, we will get enough heatsinks to cover everything that needs a heatsink though... for all we know it might come with 16 small heatsinks Unless this info is in here somewhere and I missed it? Quote
- Is fan needed? or passive cool is okay? If yes does terrahash provides fan? If no, what size fan do we need? 1 fan or 4 fans?
My understanding is that you will not get a fan, depending on your environment passive might be ok, but I wouldn't try it. # of fans you need will depend on what size you choose I guess You can see the DX large has 3 case fans on it, so you shouldn't need very much air movement for a single k64Quote

It's official. I have cancelled my Paypal dispute, as someone has agreed to invest 50% of the cost and to share the mining. I don't mind as much having 5k on the line as opposed to 10k (with shipping). I have a leased location in which I get .05 kw/h, so I will be hosting the unit and everything in the order stays the same.
As I think has been clear since Terrahash started providing updates, I obviously changed my tone once updates were being sent out. Did I overreact to the long silence? Maybe, but silence that long was very concerning in this high risk investment.
Figured I'd come here and eat some crow to show I admit when I'm wrong about something.
As an aside, here's where it will be going:

Dumb question, but if terrahash is providing the chips on our order we wouldnt need to reserve a spot for assembly right?
The service they are referring to is if YOU have your own chips.
If you bought a finished miner from their website this does not apply to you
