When shopping for a PC power supply, don't look at the total power, but check the manual for the power that's available on the +12V wires. It is usually less. Also, when have a multi-voltage supply, like a regular PC PSU, and you only draw power from the 12V, the voltage may drop more than in an application where the 5V and 3.3V is also loaded. The H-CARDs don't mind if the voltage drops a bit, but you'll get increased current, and this stresses the PSU even more.
so which PSU can You recommend? wanna be prepared before miners arrives

The fab managed to lose some of the silkscreen (printed graphics on board) unfortunately. There was supposed to be a text "ATTENTION!! Read instructions before assembly!" Now it's just "ATTENTION!!" . And also, just by the PCIe power connectors there was a text "Please use both 12V connectors & PCI polarity" which got truncated to "Please use both". There was a small tribute to Satoshi also, which got truncated. Mental note: Do not use text with multiple lines. So you are saying the PCIe power sockets were wired correctly on the board? I was not entirely sure about the pinout... intron

High efficiency PSU supports high efficiency of the chip, modularity is a plus also, and not required, but helps to keep that classic ATX wire-mess away. If you have several units on order, I think you should consider one of the bigger PSUs, so you can have 1 PSU supporting several units. I use OCZ 1250 ZX myself. Also note: if you are going to use Foofighters case, the maximum depth dimension of your PSU should be no more than 185mm. (This should cover ~99% of what's out there on the market, 1250W OCZ ZX is 175mm deep).

Any news for the august orders (StarterKit & Full Miner)? Estimated delivery date? What steps are still open to achieve for bitfury for a successful delivery of the august orders?

- Latest news is I'm going to China tomorrow to test the H-board produced on the 2nd assembly line. I'll be back on friday, so don't be surprised if I'm a bit hard to reach. - Currently I expect to start shipping next week. - We need to get the H-boards, attach them to M-boards, run tests, pack in boxes, ship.

Punin: what's up with the invoices? Will they be packed with the shipped products? I bought mine on company account and I really need the invoice for accounting purposes...

Will we receive a tracking number when the thing is getting shipped? I wouldn't mind not leaving the house for 24h in order to receive what I ordered

They DID already deliver. And you DID NOT do your homework before writing.

Update
I've added option for UPS Express Saver shipping, and dropped the prices a bit as further october orders will most likely ship in very late october. Those who picked first october orders are likely to receive theirs in very early october, if not september.
Regarding invoices: there was a problem on the site. I will need to send invoices manually. You will get an invoice, don't worry.
I need to sleep now. Shanghai awaits tomorrow. I should have more news for you in about 30 hours.

There seems to be something odd with the chip price. It currently is 1 BTC/chip, which equals around €85. A H-board containing 16 chips sells for €390. If I take €90 for the board excluding the chips, each chip should be around €300/16=€18.75, which equals around 0.22BTC ?! Maybe you meant to say 1 BTC/5 chips ?

these chips are for immediate delivery vs. october....but yes the price is still high, but that's the cost for development. it would be nice to get the price for october prices too. it's difficult to produce hardware without knowing what chip prices will be in the future. originally it was ~$25USD/chip (from the US store) for loose chips and $20/chip for counts of 3K.
one more thing...the card you buy from bfsb and megabig are downclocked to perform at 1.5GH/s. If you buy chips for your own hardware, you can potentially push them to 2.7-3.0 GH/s.

They DID already deliver. And you DID NOT do your homework before writing. October is not far away, will sojourn - we'll see. And come it will be too late when the difficulty will obesmisli everything I work. But good luck. However, throwing a lot of resources. If you have it now, immediately ... even triple the expensive price. The end of October is too late.

The october 400gh kit was 7500euro, but now it is 6500euro, will punin make refunds to who bought them with 7500euro?

If I understand it right, the 7500€ october orders will be delivred approx. a month earlier ... then the october orders for 6500€

Chip prices will only go down with time.. We will be revising our bulk pricing in a few weeks. I believe that this will coincide with another big announcement, that will make planning your own production with our chips much easier. Some people tend to make their purchase decision based on price, others on something else. We have a working product that is over 5 times more efficient than anything that has been proven to exist. We didn't collect preorders before we had this working product. This is how we choose to work, and we hope that our style will be appealing for a large enough amount of customers and developers, so that they will choose to go with us. Our bulk pricing is still competitive, but not the cheapest for sure. At least you're paying for existing product with proven specs. And we have a self-imposed punishment for missing delivery dates (price drops if we're late + option to cancel). So please choose with whom you want to work with. We will always be happy to serve you.

People getting late october orders will be missing out on approx. 4000€ in mining revenue. I think a 1000€ price-break is more than justified.

so, punin, let me get this straight...
the ones who paid M and H board earlier (1000 and 450 eur respectively) will get the hardware in late september?
and all orders from now will be delivered in late october?
