How about this:
http://www.bequiet.com/en/powersupply/330
(click technical data)
Does this have 4 rails or something?
It says max combined 12v 576watt so that should be 5 boards?
Confusing stuff suddenly with this rails stuff.
edit:
or perhaps this model
http://www.bequiet.com/en/powersupply/329
Max combined 12v 480watt, 75% if that is 360, which should be about just right for 4 boards
(and then 2 of these to run 7 or 8 boards)
yes? no?

This is weird. Correct me if i am wrong.
150W + 750W + 9.6W + 15W = 924.6 watt yet it said total power is 750 W & obviously 750 W
so maybe 150W + 575W + 9.6W + 15W = 749.6 watt
So i guess 12 V rail only 575 W, so only 5 board maximum but better use 4 board only.

Thanks for the reply. I'm glad my calculations are OK 
About this single rail stuff, I have no idea what it is. How do I find out if a PSU is single rail or not?
And do you care to explain briefly what it means? (just so I know what I'm looking at)

It's usually said +12V1 & +12V2 for double rail.
But some manufacture lie about this too so you need to find review if available or measure it with multimeter.
This is the example. it's said dual rail but the real is single rail.

I've ordered 7 boards and I'd like to run them with as little PSU's as possible. I've found a PSU with 80plus silver certificate which delivers 48A at 12v, so that's 576watt. 75% if that is 432watt, so should be enough to run 4 boards. 2 of those psu's for all my boards.
Read somewhere to hook up a simple device on 5v to make it more stable, like an old HD or cdrom drive.
Would that work?
Since you didn't specify whether you PSU is single rail or double rail, then i will assume it's single rail. 48 A at 12 v rail will be more than enough to run 4 board. So yes, it's will work great.
In case it's double rail then just make sure that you put 2 board on every rail.
About hook device to 5 v rail, i don't know about that since i also hook my TP-LINK TL-MR3020, Pi & powered USB hub on it.

What power supply would i need for these boards?
The 2Good review says about 92w needed for each one.
You need a PC power supply with molex connectors, maybe get some sata to molex convertors, and wire them into the PCI-e wires.
Best if you try to spread them 1 machine per wire, but 18AWG should be able to handle 2 Units (184w)
Get a single rail PSU (so there's less chance of blowing it up if you don't evenly distribute) and don't load it past 75%
This post is actually a bit confusing. 18AWG? single rail? Wire them into PCI-e wires?

I see that you sell both fully assembled boards with chips, and an assembly service including board.
Do you sell/ship just the boards and if so how much are just the boards and how difficulty is it to attach the ASIC to the PCB?

In order to get bare PCB you'll have to order it with PCB house

If you have a solder reflow oven -- no problem -- otherwise it's not for you.

Available on Amazon as well -- only a few hundred to $10K -- a great Christmas gift for your wife. She can cook the Christmas turkey after you solder your chips.

Hi marto, did the electrolyte capacitor had no significant contribution in HEX16A2 because i see none of them mounted in 2GOOD review

Our design is the only one in production with about 50 pieces in the customers hands already, but Avalon team liked drillbit design better.
Now drillbit have to test it quickly to put the chips in action winch is great

Marto now we're in December shouldn't you say the new orders are for delivery January?
It's a short month with Christmas holidays/delivery services and there are Nov/Dec orders still pending.
