Topic: ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH - page 409. (Read 528055 times)

 Not sure if it's same controller, but looks pretty similar. Anyone else pay attention to the "extra" fan and board slots on the controller? I don't even want to THINK about the price on an S7+ but it looks like it will be a trivial design to do.

It is all situation dependent but for most (including me) I could have made more money buying coin all year and then selling at $300 when it was in that range. However that would not be as fun, as supportive of the network, and I would have spent my money playing with some other idealistic electronic related idea so it may as well be the one which has hope to actually make a difference.

It isn't all about the money for a great number of the people posting here.
 
However, we still care about the money and the difficulty flatness over this year showed it is possible, but the power rate and uptime will determine such.
I agree the price is high, but the early adopters do get to start on ROI the soonest. So if you are going to roll the dice, roll them now. By the time people wait for the price to drop the difficulty is going to seriously pop.

Even with the free electricity, because of my countries tax rules, everything passes 1500$ gets a %40 costums fee. With the shipping cost, its almost impossible to ROI before halving.

I would say the PACMiC and S5+ was the sucker's call.  This thing is like the HA-HA afterward.  I mean they, Bitmain, knew they had that S7 right around the corner.  Yet they throw up the S5+ at a ~$2300 premium and at .444 j/GH.  Then boom what not but a week or two later drop the S7?  Dirty pool.

You will never get your bitcoin back if you buy one of these at this price. It isn't even close. This is for suckers or those with stolen electricity.

@BITMAINTECH
I would love to see some special offer for your old customers like ppl whos got 1yr old account or for ppl who bought S1 or something like that. So they can buy 1 Antminer S7 for special price maybe even 50% ? ;p U wont lose much and ppl will be very happy Pls consider that option.
Regards

The IBM 2880W will be able to run 2 of these, I'm not aware of any common PSU that will be able to run 3 at their claimed power consumption (that would be 3,390W DC total).  The ideal layout would be powering 7 S7's between 3x IBM 2880's, it would put current draw on each PSU @ 2640W, leaving it around 91% loaded.  J4bberwock is the developer for the 2880W breakout boards, I am his partner/official re-seller for North America.

You need at least a 205V socket.  If you're in the US you're looking at 110 to 120 for residential so you'd have to drop one.  Also at least a 15 amp breaker to handle 1800W, as it runs at 1280W.  I suppose it's possible you could buy a very high end EGVA gold power supply and run it.  The 1300 would be at max load so You'd want to go higher.  The issue is you need 9 PCI plugins 3 for each board over the standard 2 for the S5.  So you're going to have to buy more split cords in all likelihood to run it.  Note that is to run ONE device.

This could possibly ALSO work.

But that's a guess and these other guys are way more tech savy then me.  Either way a server PSU is going to go for a lot less then this thing.  I'm looking at this guy on the boards for possibly three units but his IBM only is pushing 2880, which isn't enough to handle three units only two.  So I'd need a supplemental PSU to handle at least a hash board left over.

https://bitcointalksearch.org/topic/ibm-2880w-psubreakout-boards-new-package-deals-for-t9s9-a7-966135

a) 3psu as in 3*at least 450w on 12v or

b) 2psu as in 1*at least 900w on 12v and another of 450w on 12v

first option is 1psu/board, second is big psu/2boards and small psu/1board

I agree with this.  I got my first S5 from Bitmain through Amazon, on purpose.  It also ended up being their 'last one' in stock, 'new'.  Even though it was a substantial mark up considering the second hand units they sold recently.  I did not want to be screwed and still got my first unit through the Amazon store.  It came from their CO distribution center with one board not firing off the bat and the other showing 1 chip down, which I think was actually in truth two chips down on the other chain.  Bitmain was always polite and respectful in their replies to me and offered an exchange, along with all shipping charges paid.  That is NOT their general policy, but Amazon makes them do it.  I returned their politeness, and accepted the Exchange.  An exchange I may say that works perfectly and I think comes from a later S5 batch because it had individual heat sinks on the outside of the hashboards as well as fins on the inside, similar to the design above.  However, if it hadn't been for the fact I had the 2,000 lbs gorilla in the room of Amazon none of that could very well have happened.

Longer ROI on that unit, now maybe NEVER an ROI given this S7, but I did finally get a damn fine unit.

so what power supply and setup would be needed to run these things? I am retarded when it comes to this stuff. took me 2 days to get my s3 up and running lol

So many lulz with that picture and the context my side is hurting
must watch that flick today

and to be on topic, bitmain doesn't need to hype this sale. They will have plenty of people clicking buy. I think the price is a bit high.
I want to also say, a couple of people have suggested I fret a bit much over certain aspects of delivered miners. I don't really care what those people think except to say, I do not think they care enough about their money.
Pay attention to the product announcements you receive, every word. Inspect your heat sinks to make sure they are all attached - the S5+ document straight up stated this, make sure the boards haven't jostled enough to lose one, make sure there isn't loose heat sink material where the heat sink wasn't cleaned out properly, check your fans, and follow the bitmain warranty protocol.
Do not buy from re-sellers. You will get screwed on warranty claims.
Most of all check the product you receive -- thoroughly! and never be shy about asking bitmain questions via e-mail and document everything! Delete nothing. You never know when a little gem will brighten your day.

There will be problems, be meticulous in how you handle them.


Sales will be open on 9pm(utc+8), 30th Aug, 2015. Shipping may start between Sept. 21 ~ 30 (if shipped out 10 days later than it, it won't be considered as delay )

@BITMAIN will the S7 be available on Hashnest when it is released for sale to the public?

Don't spam the thread, you nincompoop.
Find something to say about the S7, anything, even if you can not afford it. "It must be too loud" is a good excuse.

Yeap, already looking at Co-location datacenter services for em right now.  Just got to find a Server PSU that can run three of em at once.  I take thought some guy was claiming to be an official IBM reseller with a setup that had no bare wires which could handle the load.

Stop quoting the fraudster, you sociopath.

Sucks, won't be able to run those at home ... never

They stated it will be loud.  Just need to read a few posts back.

They got probably the same 70 dB fans on them the S5 does.  Front and back.  So expect two jet engines.
