Thanks. I overlooked this. My loss. Should of kept your PS. Live and Learn

Got my Redhash unit yesterday. I chose to use my own power supply and was in shock that my Trusty Antec 850 watt was inadequate to power the unit clocked at 328mhz per chip. It would shut down. At 300mhz or below it was fine. I swapped in my main rigs TR 1200 watt and no problems. Kill-A-Watt EZ Plug Power Meter shows 979 watts
It is because according to the specs of your Antec TPQ-850, it can only supply 768W to the 12V rails. The remainder of the total wattage is available on other non-12V rails. And per my first post, our redhash unit need 780-790W at 12V. This is why we selected the Corsair TX850M for our redhash unit: it can supply 840W at 12V.
Optimator: the wattage of a PSU measures what it can supply (output) not what it can draw (input). The maximum input wattage at the wall is always higher than what it can supply due to inefficiencies (most PSUs are only 80-90% efficient). Per my first post, we measured our PSUs pulling 940W from the wall, and supplying 780-790W at 12V, which place them below their maximum rating of 840W.

How have your redhash units behaved with your own supplied power supplies?

Interesting... I measured mine at the wall at 953 watt with the default clocking. I wondered how an 850 watt power supply could do that???
I haven't a clue. My Antec is no piece of crap 850 watt either. Hopefully MRB from TAV will chime in on ther power supply magic. Had I known I would of paid 0.5 BTC for theirs as having to use my main rigs 1200 watt PS is a pain in butt. I was up 4 hours late last night trouble shooting my power supply issues to get the redhash functional

They took a loss and most sold 20-21 BTC.

There is something I do not understand, if avalon 10,000 worth 780 chips each are 0,078 BTC BTC a REDHASH worth 15 BTC and has 320 chips, this is 0,048 BTC per chip and includes PCB, assembly components, heatsink, power supply ... chips have been giving away avalon and I have not heard or explain this?

<== Reference Bar
This is my idea of what a TAV unit will bring back if it is delivered promptly and if it is sold for 15btc. (just off the top of my head)
By the next two difficulty changes I expect it to look something like this:
Hey PL, as much as I appreciate and are entertained by your posts in all BFL bashing threads..with that said
No one gives a rats ass about your TAV purchase opinions. So much so that everything was sold well above 15btc and there are dozens of bidders who are sorry they lost or missed the bidding.
For you at least move on there is nothing of interest for you here.
See you on the BFL threads
To hail that as something to be proud of....interesting to say the least. I guess every fool smiles when they take a crap.

I seriously considered a higher bid, just because of the awsome look and engineering that went into these - these were a labor of love.
ROI? Wasn't bidding with that in mind.

You can manipulate the two bars above to get an idea of what TAV expects people to make back from their purchase.
Blue is your investment monies (if you expect to get at least that much back from buying a TAV unit.
Red is your profit monies (if you expect to get any profit back just resize the width.)
A blue and red bar of equal lengths of 300 pixels equals a full recovery of investment funds and an equal amount of profit.
$100 goes into hardware, $200 are made back by said hardware. (a 100% ROI)

We default to Priority Mail Express International, which is included in your bid price.
If you have a specific carrier in mind, we may be able to accommodate your needs. Give us your details (country, zip) at [email protected] and we will figure out a quote for you.

What a bummer: for the few of you who are not in the USA and who desire to use our standard shipping included in the bid, we found out that USPS Priority Mail Express International is not available (to all/some countries?) given the 19 kg weight of one packaged unit.
We are in contact with you guys to work out solutions.

Theoretically without representing your future plans...
if you were to build Avalon Gen2 modules would they be plug and play with the current back planes?

the english language is constantly changing and evolving all the time. When the usage of certain sayings or phrases becomes wide spread, that lexicon is integrated into the language and accepted as norm, whether it is grammatically correct or not. This is why we do not speak Yinglish the same the way they did a 100 years ago. 
True. But this is a technical term, being used in the correct context incorrectly. A bit different from street slang, dontcha know?No. And no one cares. In Bitcoin mining terms, ROI has become a bit of technical jargon that happens to take on a different meaning than the one used in fiat currency accounting terms. Just like no one pronounces Gigahash as "jig-a-hash" - no matter how many times you try to say otherwise, everyone will continue to use ROI in Bitcoin mining jargon terms (where it means a positive return - past the initial cost - of a piece of mining gear) and not fiat accounting terms....

Optimator: thanks! 110 lines of Python 
1) A quick setup guide will be included with the redhash unit.
2) We have not tried mining with an AX1200. Like all vendors, TAV does not (cannot) officially support or recommend overclocking.
3) No. Adding the 2 fans would increase air velocity, but would decrease interior air pressure, which would reduce cooling to the PSU, which would potentially reduce its operating life.
1) Setup guide for these guys somewhere ?
2) How high have you stably run these on a Corsair AX1200 ?
3) Worth it to attach two more fans to pull hot air out of the unit, on top of your presumably configured 3 push fans ?
