Topic: ANTMINER S5+ is available to order, 7.722TH/S 0.445J/GH - page 17. (Read 40128 times)

Hi all .. I am new here. 

Can someone, with the right knowledge, help me with the points below, please.

- Where is the manual?

- Is the extra wattage from the 3 PSUs beneficial for performance efficiency?

- Is there any instructions on how to start the hash boards before the controller board?

I do see that power ratio vs. hash rates is a win vs the S5, but here it stops in my calculation of reaching ROI in 180 Days or more.
Everybody seems to forget the PSU needs for this evel miner.
If you need 2 x 2880 Watt breakout boards around 340$ and 42 PCI cables for around 126$ and then last 2 x IBM Blader sever PSU of around 90-100$ for a refurb. So total you have to add around 660$ pr unit to just get this beast up running!
Thats a hughe cut in earnings....
If you use the same amount of Breakout boards, cables and Blade psu`s for an S5 setup, you are able to run 8 S5´s for the same amount of money, giving 9.6TH.
If someone can explain to me why this should be a better deal, please explain, since I cant see it :-o

Can't believe the day finally came to a new Miner being released? Any reviews or videos on this product out yet?

Not sure what you mean by that part in bold part.

I'm not worried about frying my controller from simply adding a relay. That kind of thing is something I tell people how to do over the phone a couple of times a week. I'm more concerned about posting pictures of how to do so and then having my warranty voided, that is if I went that route. I won't do so for the sake of warranty until I know something in writing from BITMAIN.

I should have been more clear in my reply because I mainly wanted to point out to anyone who hasn't noticed the product specification page states you have to power the control board after the hash boards are started and most people are going to need a separate power supply for doing such until they are shown an easy way to do it. Many people aren't going to know how to do this, that, or the other which accomplishes the same thing. That is obvious from how many people purchase on / off switches for the mobo on / off for their ATX power supply. Not that some don't do it for other reasons, but I am talking in general a lot of people purchase that particular part thinking they need it, or it is a requirement. Remember the thread about the 20 dollar "special" paperclips?

I will shoot a ticket over to support and ask the same question about the relay to test the waters.

I can't answer that, sorry. Worst case you're frying and paying for a controller, can't be that expensive.

The product page specifies the controller board must be powered on after the hash boards.

I will use a seperate smaller gold or platinum atx unit, or put a time delay relay inline with the second 2880.
The relay wouldn't void warranty would it? It is still being powered on after the hash boards.

Its pretty accurate, single voltage PSUs tend to be very efficient and the power measurements are taken from the wall.

I'm guessing you are wanting to hid from 1 activity.  But when looking at watts this high going from ATX to server psu's can save you a lot.

Someone can go out there and compare.  But unless there is a big deal/bargain on a good ATX server PSU's win on price anymore.

Do you think it's going to work at 90% efficiency with their own PSU power supply APW3-12-1600-B2 https://bitmaintech.com/productDetail.htm?pid=000201505040743496917U7kGsCm0694  (Note they claim 93.8% efficiency)

Or is that thing just a POS under normal working conditions and we should stick to normal computer PSUs?

I'm a noob here so feel free to correct anything I say.  Also forgive the grammar mistakes and spelling, just off surgery and painkillers and typing don't go together.

Question 1:  Does anyone know the size of Batch 1 production run?  (In other words how fast is the network going to explode with centralization and difficulty through the roof)  
Question 2:  Does anyone know when the Batch 2 Production run will be available and its size?  (Are they doing reserves? in small stock (IE I don't buy 100 of em))

Comments and analysis on the Hashnest offer.  I looked at the contract (and going over legal contracts is part of what I do for a living).

I'm agreeing with most other people on the Hashnest deal.  That's basically a loan so you can finance their capital costs on revamping/retooling their own data centers (probably with beefy miners we haven't even seen yet), and perhaps production operations.  While doing that you get a small 'bonus' (in the financial world we call that interest) in the meantime until that principal is paid back.  And the 'bonus' is variable rate they are paying YOU for that loan is a lot lower then what a bank would give them (variable interest/bonus rates they are letting a volatile market decide).  And they have the ability to STOP paying you if bitcoin takes a crap, their costs skyrocket, or some other disaster happens.  Which is a big no no.  

Go to a bank and try taking a short term business loan out.  Tell the bank you want the clause put in that if your business model becomes unprofitable and you haven't paid them back after 120 days that you stop paying them back and they do not get any accrued interest or principal payments during that time period.  But should your model recover, you will start payments again.  Oh and that YOU not the bank gets to decide when that period starts and stops, and that it can start and stop at multiple times.  And the stopping can include the time period of forever.  IE  Never paid back with no collateral.  See how fast you get laughed out of the building, if not escorted out by security.  Hench why they are trying the cloud mining contract deal.  Sucker born every minute as they say.

Second thing, or are we at three at this point (Hell I don't know):

I also did a quick comparison between their second hand S5's they are selling (of which I just purchased two literally a day ago).  And the new S5+  All these things are from the bitmain post or their own website.


First Warranty:

Second hand unit, (don't know what they it through)  Only get 30 days. | S5+  New unit, 90 days.  However these are Solid State devices.  If taken proper care of they should technically last forever.  (We all know that's not true but you get the point.)

Hash Rates:

S5:    1155 GH/s      70.4 or so dB fan (AKA Loud as F)
S5+   7722 GH/s   6x70.4 or so dB fan (AKA Data Center Unit, Loud as F x 6  Never gonna be a home miner unless you got a sound proof basement)  

Only good thing is the cooling system of individual sinks seems much more efficient on the S5+.  That's also probably partly why the operating conditions increased from 35C to 40C as a maximum over the S5 as well.  It also means the product can likely stand up to a lot more wear and tear before components start giving out due to heating and cooling.  IE they just improved their manufacturing processes.


Price to GH/s:

Second hand:  $351 (when I got it, now 348 today, but I'll work these off my price.)
S5+:              $2375  On their website

Now remember this is basically 6.5 S5 miners or so strapped together, units with three boards each.  So lets to a Gh/S to $ comparison.  Also I'm looking at a brand spanking new unit vs a second hand, but both do have at least some warranty coverage and can be tested and nailed out of the box.
$351 gets me 1155 GH/s
$2,375 gets me 7722 GH/s

$351 goes into $2,375 = 6.766x  (I know you cannot buy a .766 of a miner but humor me)

So I could buy 6.766 S5's for the price of an S5+  Simple math 1155 Gh/s x 6.766 = 7815.17 Gh/s  Then let us do the math of that between the two:  7815 Gh/s / 7722 Gh/s  = 1.012  

[b]IE  You're actually getting 1.2% better return on Gh/s for $$$$ spent with the simple S5 over the S5+.[/b]


Power efficiency comparison:
(I'm not doing power consumption comparisons because where I'm at that's irrelevant.  Maybe where other people are that is important.  Efficiency is the key for me.)

Now here is the bright spot where the S5+ seems to really shine though and where all those engineering dollars went.

S5:     unit is 0.51W/GH
S5+:   unit is 0.445W/GH

Math:  .445W/GH / .51W/GH = 0.8725

This means you're using almost almost a full 13% less power from an S5+ than running multiple S5's.  12.75% less power to be exact.  That would be a significant impact on your electrical bill if you're in a high kW/h area.  Then again, if you're looking for a fat tax write off because you're smash and grab bitcoin seller paying ordinary US tax rates (which will be most home people) and you're working this as a cottage business in your basement, that's a business write off you're going to lose.  

PS:  Regardless I'd take the lower operating costs, but this is definitely for people who have committed space for serious mining operations.

Overall Summary:  GH/s ain't that great for the price, but the 12.75% discount on the power usage isn't too shabby.  Someone mentioned breaking these up into multiple units.  I'd have to see the specs and re-run the analysis over on that single unit to see i that was worth it.  Especially at the price of $800 per single unit they quoted, which is a slight premium over the 3 stacked units.

Cniht  

Itll be about 90W for the fans, 20W for the controller and the rest is PSU inefficiency. I calculated with 90% PSU efficiency so at 93 it makes it 170W per PCI-E when using 2 a board.

Exactly!  I don't see any benefit in helping give Bitmain an advance on their operating costs.  I enjoy mining as much as anyone.
But only if after the principal is paid you walk away with used S5's or some collateral, other than that it's a loan. 

So each of the 9 hash boards draws about 330 watts apiece?

So the remaining 500-sh watts is for the fans and the controller?

Thanks! Could not find this.   To bad they did not make it only use 2 of these PSU's it's close on watt's.   

But I guess PSU's were not big decider on when they made this unit.

12x PCI-E

So how many https://bitmaintech.com/productDetail.htm?pid=000201505040743496917U7kGsCm0694 does it take?  Also how many PCI-e cords does each one have?

It seems like it would be 3 of those.  But I could not tell if they had 6 or 8 PCI-e cords from pictures.

Crap, looks like I missed out on batch 1.

When is batch 2 planned?

Looks like batch 1 already has been sold out for sure, has not shown up with available again.

2 is fine, still only about 165W per PCI-E.
