I wonder if there will be any problem combining several old power supplies to power knc miners, since I have few lying around.
Dude I would stick with the 80+ standard certification, downtime costs coin, killing your machine is also not profitable. Play it safe man. Love the username.

Also with regards to all this ROI nonsense. Two things;
1. Did the OG CPU/GPU miners know Bitcoin would increase the way it has? No. They were hoping it would, it's only now just began to gain momentum, and that depends on innovating mainstream uptake, ease of transaction, and availability to exchange, which is pretty sad most people concentrate on mining over this, it's where the profit really is.
This is because it takes brainpower to innovate and turning a box on takes none, and as a lot of the comments here prove Bitcoin mining is now full of the latter. I can only assume most are n00bs that have become interested subsequent to the media interest from the Cypriot ECB theft fallout, or were just plain daft prior, but I find it hard to believe many of the recent posts are from individuals, capable of handling command line code and GPU rig assembly, handle heat, etc. Clearly plugging in, and flicking 'on' is testing the limits of their intelligence, if they cannot navigate the reasoning behind recent hashrate multiples being the result of thr transition of GPU rigs --> what
few ASICs devices have actually surfaced after the fraud that's occurred with BFL, and Bitsyncom.
Therefore you are still purchasing with the intention Bitcoin will move north over time, that is your real ROI if you must fixate. You'd have to be stupid to believe whilst profit margins over electricity exist people won't keep piling in to profit over a box they just plug in. How can you not expect this to got the way GPU farms once were? Oh right you were never there in the first place.
2. Ever heard of FinCEN (the US Finacial Crimes Enforcement Network), or the FSA (UK'sFinacial Services Auhority)?
NO Bitcoin mining company can promise a 'return on investment', promise to 'protection for your investment', or even mention the word; 'INVESTMENT', unless they have met ALL the requirements of a heavily regulated finacial services product. None of them have.
It is illegal. This is why under Bitsyncom's 'No Bullshit Terms', they should actively be packing their pants, as they are a US incorporated company that promised just that, and claimed to price accordingly. This is very, very serious and any company offering such terms is quite frankly, screwed, and lying to their customers.
If I purchase Avalon Unit right now when can I expect to receive my unit?
At the time of writing Batch #3 is expect to start shipping early May.
How is each batch’s unit price determined?
The price of each unit is the current mining difficulty which at the time of writing, just got readjusted to about 6,695,826. We take that number and multiply it by two ( predicting the network speed will double. ) and calculate the return in a thirty day window, which is about 75 bitcoins. See this site for more details.
Avalon ASIC Chip
The no bullshit, no fine print terms of sale
the only payment accepted is Bitcoin.
these chips will be available until at least end of the year, 2013.
spec and various information is available on the wiki
the chips being sold are packaged and tested.
the lead time on the chips is 9 to 10 weeks,
made to order from TSMC foundry, this also means no refunds.
the order quantity is 10,000 chips.
the chips are identical to those in the Avalon units.
communication protocol, reference board design can be found on github.
everything will be open source from FPGA to PCB design.
30 sample chips will be provided 4 weeks into ordering per 10,000 chips.
we do not offer technical support of any kind, this is final.
if you do not know what to do with the reference design / packaged chips, please do not purchase.
Please read the above carefully, as with all things Bitcoin one should treat this as an investment and make the decision best for you based on the liquid-able funds available at the moment when placing an order.
I accept the terms and the potential risks involved with placing an order.
