Update:
Hosting: The switched PDUs and PSUs are arriving early next week. We have chosen 550watt 80+gold PSUs to give both high efficiency and fine grain control for power cycling boards should the need arise. Each PSU will power between 13 and 15 boards, depending on the final power usage. The PSU will then be connected to our switched PDUs, which gives us the ability to power cycle the PSU remotely. The network infrastructure and configuration is nearing completion, and we will be ready to receive the units once they are assembled.
Hi SB, maybe you should consider revising your choice of the PSU or plan less boards per PSU. According to the best practices you shouldn't run a PSU at more than 70%. So a 550W PSU would be most efficient running at 385W. 12 boards running at 32W each would consume 384W and with slight overclocking even 12 boards would push past the 70%. +1 on the case. Is that 21 boards in there? I wonder what would it look like once you plug in all the cables. Cheers 24 x K16s. Cabling should be neater than you'd think as the design is based around a central controller and power distribution unit PCB (CCPDU). Two wires will run to each of the "blades" (composed of 3 X K16s) where the wiring will then branch out to individual boards. So only 16 power wires running throughout the chassis. Data comms are another thing, but the plan is to use an I2C chain terminating in a single USB connected K16, which will in turn be connected to a Beaglebone Black which will act as a controller and cgminer/bfgminer host.

It’s amazing what open source and honest collaboration can do on short notice. I’ve seen companies of 50+ people struggling for months on similar projects and not pulling it trough. If Bitcoin can foster such effective collaboration between random people, there’s got to be something of value in it (regardless any exchange rates)
I've been admiring this about the BTC community since day one. It's nuts what some people are able to do in this economy. Exactly so. Just imagine what could be accomplished in what time frame if even one of these bozo vendors would actually deliver their chips.

Based on Bkk's most recent changes to the K16 power distribution will be done via 6 pin molex ("PCIe") type connections.

I placed my batch 7 order 2 days ago but haven't received a confirmation that payment for chips has been received yet. I'm thinking Steam is just busy getting everything in order currently, hopefully it comes soon.

This is most likely the issue. In the past 24 hours BKK released what he believes is the final revision of his K16 board. SB is probably lining up the parts for final changes and stuff now and working his ass off with the rest of his supply chain. With production expected to start very soon I'd be surprised if SB has much free time at all. I know it sucks waiting, but every time I've had a question or placed a order or whatever SB has gotten back to me and always had a great answer. Nothing to worry about. Just time. The enemy of all.

I agree. I own a small business (nothing at all like Steamboat's of course) and... Time... Time kicks my ASS every day 7 days a week. Good ole time

Hi, does anyone know a good (cheap) source of PCI-e power splitters, SATA to PCI-e, and 4-pin molex to PCI-e cables in bulk amounts? I'll need something around 40 PCI-e splitters, 48 SATA-to-PCI-e and 24 4-pin-to-PCI-e. Also, I'm interested in any good prices anyone's found for 550W 80+ gold PSUs.
thanks!

Is your K16 going to use the v0.3.0 revision board, and are you planning on using the 25 Amp buck reg (IR3847) for the banks or the original 16A one?

A quick question about testing:
I was thinking I'd get the DIY kit because I plan on stacking 6 boards. According to the OP and the website, testing is only available with the fully assembled version. Does that mean that there is no testing done on the assembled version that comes with the DIY kit? Is there at least some kind of confirmation that the chips are good? I've got a few chips in reserve, but I'd hate to have to round trip a board or two just because I didn't want to have to take apart the fully assembled kit to stack it.
Thanks,
-Jay

Jay,
From my understanding on the product page:
Assembly Only: Klondike mainboard assembled together with separately purchased ASIC chips to produce the core of the Fusion 16. This option is recommended only for customers using one off designs of the remaining items necessary for a fully functioning unit.
DIY Kit: Similar to the assembly only option with the addition of a DIY kit of final assembly parts for those who enjoy putting things together. Beginner to moderate skill level required.
Full Assembly: A fully assembled, functioning miner ready to be plugged in and begin hashing. This finish level comes with the option of in house testing to ensure full functionality of the unit prior to shipping.
So Assembly does not include all the final items (heat-sink, etc) and DIY includes all parts, but not assembled. If they don't do a full assembly, how can they properly test the unit, which needs all components installed and assembled?
Secondly, why would you need to assemble yourself to be able to stack it? Was that stated somewhere in the BBK thread or otherwise?

+1 Important question regarding the board revision. I'm sure he's using v0.3.0, but can someone confirm?

As i understand it there is no pcb design ready for the ir3847, it is not a drop in replacement, the p/s section of the pcb needs to be redesigned. I think I'm going to remove 4 chips from each board and overclock the remaining 12. Alternately it might be possible to build a separate pcb with the ir3847 on it.

It was all a little unclear to me, that's why I asked the question. In response to your questions: I read the description in the OP and is sounds like the "testing" is a burn in that would require the heat sink and fan be assembled. I want to know if there is any testing done at the assembly/DIY level that at least confirms that all the chips are working at the most basic level. I would think you'd be able to do that just by applying power to the board. As far as stacking goes, if you look at the rendered imaged of the stand-alone miner and that stacked versions you'll see that the fan is in a different orientation. That's what makes me think that the'll require at least some disassembly to stack. Thanks, -Jay

Don't read too much into the renders, they are illustrations more than anything. Which images are you referring to?

I'm pretty sure that when the board is single the fan mounts on top of the board. But when you've got multiples the boards mount on top of each other and the fan goes on the side.
