Your website says there are currently 2 in stock.

Please take a picture of both units with a piece of paper with your username and date written on it.

If you cant do this then your website is a scam and Blockhunter is a sock puppet account as quite a few of his posts seem to be randomly telling everyone how great your services are.

It's up on bitmain.cn as well as this Bitmain related site.

it is 19000 CNY that is 3058 usd

This price will cause you an issue if you ship it to the USA.

Anything over 2500 USD has import problems.

So if it is real and it looks real it simply costs too much for a home miner.

Too bad.

Needs to be 2499 just to avoid import tax issues.

6 overclocked s-5's = 6 x 1300 that's 7800gh  at 600 676 watts each you are doing  3600 4056 watts

this does 7700gh at 3400 watts    a savings of 200 watts

No offense intended but if you have been here a while you'll be aware of the scams that take place.

Repeating myself once again this appears to be a real product.

It cost too much.


if you live in the USA and do imports over 2500 there is a lot of extra paperwork.


  Two 3 piece orders of s-5's  cost = 1288 + 1288 that is 2676 shipped   for the s-5's

the s-5+  is 3378 shipped


one does 7800gh at 4056 watts

other does 7700gh at 3400 watts


so to save 656 watts  you pay 702 usd   

two separate orders of s-5's no import duty issues
1 order of s-5+ import duty issues

656 watts at 10 cents is 48 bucks a month so in 14 months you make up the 702 price premium

This item is absolutely senseless to buy at current pricing.


Now maybe the s-5 goes out of stock and the only item offered is this one.  When that happens then you won't have a choice.

right now just buy 3 s-5's and order 3 more the next day.

6 overclocked s-5's = 6 x 1300 that's 7800gh  at 600 watts each you are doing  3600 watts

this does 7700gh at 3400 watts    a savings of 200 watts



No. Even at 220V  6 overclocked s-5's  need more, as 3600 watts, if you use bitmain PSU-s.

No. Even at 220V  6 overclocked s-5's  need more, as 3600 watts, if you use bitmain PSU-s.

yeah I thought I corrected that.


at 1300 1 s-5 does 676 watts x 6 = 4056

I have it correct here
https://bitcointalk.org/index.php?topic=1146965.msg12085674#msg12085674

I went back and fixed it here

https://bitcointalk.org/index.php?topic=1146965.msg12085484#msg12085484


so this big new s-5+ is 7700gh at 3400watts   and 6 over-clocked s-5's are 4056 watts

you power savings is 656 watts about 48 usd a month (at 10 cents a kwatt).

price is 700 usd more  which takes 14 months  at 10 cents a kwatt.

Basically it is just plain over priced.   

 If it cost 2675 shipped  instead of 3378 shipped   you could argue it was better. Since you are paying the same and saving 50 a month in power.

The problem of it costing more then 2500 would still exist. You get import duty issues over 2500.

iTOP introduces the newest bitcoin miner The S5+ from bitmaintech, The S5+is the upgraded version of The S5, it uses The BM1384 chipset , S5+ brings  totally new innovation designs for the cooling system , the hashrate of a sigle unit reach up to 7722G/s, powercosuming only 0.445w/GH, antminer S5+ is the  highest hashrate and most optimal power/performance miner all over the world.


 A Spondoolies SP20E can achieve the same efficiency as this unit claims, which is noticeably better that the S5.
 The new Sfards unit can achieve even better by a bit, though the reliability of that unit is looking distinctly "early Gridseed".

 Is there a reason you insist on selling these in a no-rack-mount configuration despite their rackmount unit sizing? Would make more sense to sell them as individual S5-sized units, NOT as triples.

 The price is WAY too high to ever be able to ROI on the unit, unless the rate of difficulty increases drops to under half of this years "so far" rate, or bitcoin value kicks up a LOT.

 The "cooling" design is a sad joke, the airflow is way too constricted and passes over WAY too many heatsinks to work worth anything for the last couple rows of chips in the air flow path. "push pull" fans do NOT double the airflow, the ONLY thing they do is reduce the back pressure allowing a SMALL flow rate increase.


 These comments assume that the unit is actual, not just a good photoshop job scam or a picture of a prototype concept that is a REAL BAD IDEA at best. <edit> just saw Bitmain confirm the unit is real, which doesn't affect my other comments.
 0.45 efficiency is not enough to make this unit viable for a significant length of time IF AT ALL past the block reward halving next summer, any more than the S5.

 If you wanted to make a unit that WAS viable past the halving, run 20 chips per chain not 16. That would unleash the REAL efficiency potential of the BM1384 and might actually rival the NEXT GEN units that are on the way from Bitmain and Innosilicon (I discount BitFury and KnC as neither sell to end users any more).

 I would anticipate the S7 finally being retailed within a week of Bitmain selling out their last used S5. Possibly up to a week before, more likely the same or next day, possibly as much as a week later.

 The only way I could be more certain that the S7 is in production would be to see operating S7s in the Hashnest farm or in Bitmain's manufacturing place in person - they've got to be replacing those used S5s with SOMETHING after all.

Strange way of unveiling a new product, learning about it from the distributor.  Seems Bitmain reached deep into their pockets
and pulled out a bunch of lint. Cheesy

Maybe Bitmain has no intention of selling this themselves, they could've been special gear for larger farms who paid big $ to get the most hash / power they could squeeze.

Now some of them are unloading to make way for new stuff?

Most likely this was a unit to be sold domestically as a smaller batch to finish off the chips, will see.

It is on bitmaintech's China website.
