so... x27 6pin pcie cables per miner....  im planning to use 3 hp 1200w power supply per miner... but.. 9 cables per power supply ..  Huh this seems hard to do... anyone knows where to purchase those 6 pin pcie cables awg 16.. ? Smiley

If you use cables like this , you will need 9 of these . more tidy , main cable is 12AWG , and split is 16AWG .

If I was reading right, X28 6pin PCIE. Needs 1 for the control board.

Of course we'll see another batch. There's no way that the S5+ is a one time event. But at this late stage there's no way it will run as long as the S3 did (what was that, 6 batches?)

Here's my fantasy:

1. BTC amps back up to the $1000 range just before Bitmain announces batch 2. They price accordingly at 2.3 BTC per S5+.

2. I place my order.

3. BTC drops back back to today's $240-ish.

4. Difficulty stagnates.

5. Profit.

Don't laugh. It could happen.

today it is $220-ish.  Tomorrow will be $200 ish

Yes, it's not exactly heading in the right direction...

I've got a new fantasy now. On the new BM1385 chip announcement thread, suchmoon pointed out that the S3 was shipped a mere 2 weeks after the announcement of the BM1382 chip. If that means the possibility of the S7 being released in the first week of September, then I'm glad I missed the S5+ boat.

If there is another batch of S5+'s, they had better be heavily discounted or I'll just wait to see what happens.

Here is my first testing with a S5+ - https://bitcointalksearch.org/topic/hands-on-bitmain-antminer-s5-notlist3d-1157426

Finally got something big enough to need my 240.  Pretty amazing as far as footprint they put over 7T is a very small area.

You can use as many PSUs as you want as long as you don't have multiple PSUs powering the same individual board (of which there is 9).
Do all PCI ports need to be powered?  Or will it run with 2 on each board?  
2 is fine, still only about 165W per PCI-E.
Are you certain that using 2 is fine? The product description page says all three are required. It may be that each PCIe plug powers a specific set of chips; the 3 PCIe connectors may not share a common power bus at all as in, say, the S3 design. Without knowing the actual S5+ design, or having an actual unit to look at, saying "2 is fine" is only speculation at this point unless something more is known than what bitmain has disclosed so far.

Bitmain could confirm this here, but they aren't posting much these days. If anyone already has a unit, they could also confirm whether using 2 out of the 3 connectors works and post here.
What Bitmain customer Service told us was we have to use all 3 connectors for each board, As my understanding if each board need at least 382W(3436/9), in average each connector should be bear [email protected] , and if it works  using only 2 connectors instead that will be [email protected] for each connector , it is high risk to heat up or burn your cables if they are not good enough.    
This still doesn't answer the question of whether all 3 are *required* by design, or can 2 be used if the cables can handle the increased current?

BTW the power requirements aren't as high as you mention: 3436W quoted by bitmaintech is at the wall, using a 93% efficient PSU. So the DC power to the S5+ would only be 3436*0.93 or 3196 watts, or 355W per board. *If* the design allowed the use of 2 connectors per board, this would put 178W per connector (14.8A). This isn't bad, considering S3+ units can easily be powered with 2 PCIe cables and those use around 355W as well.

They make a big deal about using 3 per board, so I would not try to personally.  They actually ship a piece of paper with some general instructions, and an email with it to.   And in all of them it made sure you use 3 per board.

So under pcie specs should it run if high quality psu with nice cables... yes.  But they make sure to tell you only run with 3 in each.  If you do 2 i'm sure it violates warranty.

Further, we can look at this from a historic perspective. Has there ever been a mining product from Bitmain in the past that only had a single batch? Even the U3 had 2 batches, and it probably was a niche item.

Yes.
Antminer S3++
and Antminer L1
https://www.bitmaintech.com/productDetail.htm?pid=00020140830074550960Um75pnzg06E3

I think that we are still seeing S5+ batches, but only used miners, and not before a couple of months.

I thought Bitmain killed their entire Scrypt Miner ASIC project along with KnC.  Weren't able to pull it off, especially when some of the script coin people were warning they were going to intentionally try to FUBAR things for those units should they start shipping them with slight changes.  Not saying there aren't some small scale ASIC in capable of script mining, just they were going to intentionally make the script more resistant if major manufacturers got in the game.  Seems they didn't like the thought of all the centralization occurring.  (Not like it isn't happening anyway)

regardless of "x" amt of batches, s7,8,9,X,11 & so on ... end of the day it WILL always be :

TOO EXPENSIVE !
-almost no chance of ROI *unless FREE or SUPER LOW elec rates*
even with that if i'm not mistaken it'll take a minimum of 4-5 months with FREE elec. excluding psu+cable+taxes+0 downtime+100% luck+PERFECT scenario
-prices will always change along with btc price
-miner issues with S&H, HW, FW etc

if you the buyer DO NOT have FREE or super low elec. rates, imVERYho FORGET about it ! DO NOT BUY. buying STOPS so does the KILLING !

most people till now really surprises me that they DO NOT:

-take into account of diff jumps or reduces bla bla bla but always put it at WORSE case scenario 
-also use a lower prediction of BTC prices for ROI calculations please
-add in shipping ! or any taxes if applicable
-psu, cables, fans, etc . . .

just ma couple of sats. $ is yours, decision is yours. atm things does look -ve

Cost almost 10 BTC due to prices ill pass on that and buy 10BTC instead and wait on price make more of BTC trading than mining. If got free energy then so be it good to take a gamble but right now not for me ill maybe buy some cloud mining and take gamble that way than risking 10BTC to buy equipment wait on delays and problems on first batch. No doubt their is going to be problems on first so maybe wait and buy later.

I doubt it will be quite that low, with the efficiency improvement.

 And who the heck figures in GH any more anyway? 8-O

....  Also we don't know price of S7.


This is the easy part.. S7 price will be 0,0011-0,0013 BTC for 1 GH/s

Hmm what makes you assume that?

S5   1.3-1.5BTC
S5+  8-9BTC

My bet is that the recent announcement of the BM1385 chip (for the S7) will curtail some of the demand for the S5+. Some folks will wait for the S7, currently unkdefined schedule, some folks will just take the S5+ now if they can get it.

The actual announcement of the BM1385 chip, even without an S7 schedule, will likely reduce the overall demand for the S5+.

I think it will effect it and other miners.   It will all depend on when the S7 comes out.

As of right now we don't know much just some released specs.   So S7 could be very soon or could be months they don't really say much on when S7 launches.  Also we don't know price of S7.
