I think that this purchase would be a disaster.

This is S9 design with older S7 chip.

The same disaster, as S5+  before S7.
..................................................
Now you have to know the S9 parameters

5.Dimension:306mm(L)*150mm(W)*275mm(H)
6.Cooling:2×12038 Fan

With this they can also replace their ageing ATX PSUs... Wink

Those psus come from the s2

not worth buying with the psu.

shipping cost for that psu is a waste.

Too bad   as it is a decent format.

Would have been nice if it came out in December  without the psu.

Seems like they are trying to move the rest of the S7 chips out the door to make room for their S9 chips.

 I would love a few with s-9 chips and no psus


I could put this psu instead as I have a few of them

I can't really make out the configuration, but is this roughly 2/3 of an S7, with the ATX PSU on top and two fans? The 90 chips sounds like two boards. The power requirements and hashrate don't quite fit the "two thirds of an S7" theory, but I'd be stunned if they actually engineered another board for the BM1385 chip at this late date.

As packaging goes, it's pretty obviously a "paste up job" of existing parts (except for the top PSU mounting bracket).

I know I will pass, though I don't think Bitmain will miss my non-purchase.  Smiley

My crystal ball says , it is the ancestor of the S9. It will soon be seen.  

S9 will be two blades small miner,  with the possibility of fixing the power supply unit or with cheap CPU on top

Basic Dimensions: 301mm(L)*123mm(W)*155mm(H) without power supply holder

works for cheap power guy that wants a quieter miner.  but so does unplugging a board on a real s-7 then down clock the two left from freq 700 to freq 500

Hmm. I think for a cheap power guy that wants a quiet miner, you'd want a severely undervolted version and not those fans. When i looked at the price, i told myself:
"I dont see any upside, if i was to throw money away, i'd buy a S7 and underclock that, which would give better results, I think."

On the small amount of "free" electricity i have, i have been running my now obsolete S3/S5 on silent or aftermarket fans.

I don't know maybe this fill a niche somewhere and i just don't see it.

This is literally just a 2 blade S7 with a dumpy pc ATX power supply. At this price you may as well buy a normal S7 and trade someone the extra hashing board for a quality PSU if you want to run something under 1000w.

Plus as the other guy said, this is a limited run only available in China.

Stop buying industrial miners, running them at home, and then complaining about the noise.

Very interesting I wonder what if anything ever happened with the U4 does anybody know.  When I started mining I started on the U3 and I always have hoped for a U4 but I've heard nothing about it.

The same thing that happened on the S6 and S8 i believe. I don't know if Bitmain plan on doing any other small miners again, but it would be nice. My absolute best IMO is the S3. Some S3 with S9 chips would be sooo nice.

With the current network hash rate and difficulty I cant see them creating smaller miners as they would never be able to achieve ROI.


I want larger, faster, rack mountable units personally. Id rather monitor 1000 large fast machines than 10000 tiny lil S7 style miners :/

same my power cost is kind of free i just never really admitted it or said so because i pay it back in other costs i pay in my house like cable phone etc . i don't have to but do any way and it's few 100 a month and even pay half the power bill from time to time, on top of rent food the normal stuff .

that's exactly why i keep running s3 s5 and a4 etc even some old ass script miner thu i just retied one took it a part and thu away the inside,molded the case some then put in more up to date script miner boards .
I like doing bitcoin and alt coins one can and does off set the other.

not all of us are need it to do ROI and would like to keep mining in our homes.

at my age i don't think i would want the hassle of a 1000 miners i would go 50 and be happy . and it is a hassle from day to day rather you admit or not , it's also fun but it has it's down sides etc.



If you don't care to ROI and want to mine in your home buy an S3 instead.  It secures the network just as good, and you will lose less money.

You're welcome  Grin

On a side note, I agree paying too much for a POS PSU (if it's the same as the S2) and additional shipping costs.  This seems like a step backwards, and only good to dump old parts on suckers who don't understand the halving.  I much prefer the S7 design myself, from both a practical and a biased, self-interested point of view (server PSU's).

Well, like everyone else.... I just hate it. A two board S7, great idea if it had been done a few Months ago, with a PSU that noone needs or wants, pushing up the shipping cost at a total price which is very close to a batch 17, 3 Board S7.  Duh..... Must mean that S9 is close?

I am not sure how staring at a loud piece of tech pumping out heat while costing you money makes sense for anyone. I mean the whole point of mining is to make a profit is it not?  You may as well crank your house heater up, open all the windows, and just watch it waste money if thats the case. No special hardware, no reboots, no mining pools needed.

Stop buying industrial miners, running them at home, and then complaining about the noise.
