S5+ coupon's are 100 it appears.
August 30, 2015, 07:55:13 AM
I am new to coupons. Today I received 10 Coupon counts which says AntMiner S7 Coupon 100 USD. Does that mean I have 10x100 USD = 1000 USD Coupon? Can these coupons be used all at once or 10 orders separately?
They have never been stackable, assume they are sticking to the same model, that means you can buy 10 S7s at $100 off each.

Looks like coupons have been sent out.
Got two of em. Looks like they paid attention at least a little to the price point being a bit scary for people.
how much is the coupon worth?
I could use one if anyone has one to offer.

I have donated more then 20 over the last year or so.

The difference here is that the S7 has two fans and temperature control / cutoff, as well as much higher quality heatsinks.
How do the heatsinks on the other side of the board look like? Are they glued on also?
Very similar to S5+. I don't know how these will be attached but the early S5+ heatsinks were thermal taped and the later ones thermal glue'ed.
So are there pictures of the other side of the S5+ heatsink?

Mining still dead in the UK at $0.23, and shipping to a host is probably going to be a year to breakeven when the inevitable diff rises happen so no new machines for me 
Who are you with, I'm on 8p/KWh (0.12$/KWh). 
August 30, 2015, 06:43:25 AM
My usual spreadsheet, people have said it's been useful in the past.
Price doesn't include shipping, import taxes if applicable or PSU's. Assumes static diff and BTC price, it's just to give a rough idea

This says it all
WAY OVERPRICED.

only 25W for 190CFM?...
because they are 25mm fans in the 38mm frame
that's why the screaming noise!

- Operating Temperature: 0 °C to 40 °C
Operating Temp is really low 40C? Other miners as well as bitmain units operated up to 60C.
That is only 104F or so. Hope you got air conditioning or live in a northern region.
The S5 has a limit of 35C. These are ambient temps, but I can see a data center getting higher than 40C and certainly higher than 35C without AC.
I'm sure there's many S5's that have been running at ambient temps above 35C in the past couple months. Any performance issues?
After my experience with a burning AsicMiner Prisma with ~1100 watts passing through a very small area, I think that I will pass on this miner. That is just too much power in a tiny area in the event of a fan or cooling failure.

The S5 fans are appx. 1.9 amp 190 cfm, as far as I've been able to figure out. I haven't been able to figure out the exact model number or find a spec sheet though, as the FFB series fan member they APPEAR to be (based on the power draw I've seen stated and on the appx. rpm) doesn't have a PWM version per the Delta web page, and none of the PWM flow-director style fans I've seen on that page have as LOW of an RPM level as the S5 fans.

Might actually pick one of these up. How much is it again?
Looks like 7.972BTC
ouch!
Using www.tradeblock.commining calculator at a 229 usd btc price....well ...see for yourself
Probably pays for their own use Data Hall thou.It figures at 13c kwh this beast (usa) don't fly for me in anyway shape or form
Thats for sure. Too rich for my blood August 30, 2015, 04:48:47 AM
Guys, can you use two 750W PSU to power this miner ?
maybe if they are identical, maybe but is too risky.
the point is that you will have to power 1 board from both psu's and that is not recommended!
u can use 3 of 500w
u need single rail psu with at least 35A on 12v . the one psu that is powering also the controller and the fans i'd say at least 38A!
30A and 35A or so to be picky, but better to go 35A and 40A+ so you have a bit of headroom in case the specs are off at all, and quite a bit more if you plan to try to overclock it.
If the fans are the same as the S5 (they appear to be using the same model from the pics AND what specs they've published) 2 of them will eat right about 4 amps for JUST the fans, then add a bit for the controller board logic and BBB.
I'm not aware of any 500W power supplies with 35+ amps on one rail, but I'm sure there's some out there somewhere - I've got some 450s that manage 39A split between 2 rails.

wow this seems very powerful and also most power efficient miner in the market ...
but i dont think the price is acceptable though.
but i dont think the price is acceptable though.
I have to agree. Unfortunetly the size and price of it is bigger than I expected. I was expecting a 2.5 ths unit with around 3-3.5 btc price. Seems like I'll have to wait and save some more coins.
And it does look loud. Those fans look like S5 fans and I can't imagine 2 of them in a house.
Yes. It could be very loud.
I don't really find anything definite for "12038 Fans"... What's the specs? Thanks.
I remember seeing something SOMEWHERE about "4200 rpm" fans, which makes them probably the same Delta model that is used on the S5.
Does anybody know the power draw and CFM? Or even better, a data sheet?
August 30, 2015, 04:39:47 AM
@Bitmain: Will you offer this one at DHGATE.com also? Does it run on WIFI?
I'm sure they'll add it to their DHGate store shortly, it's only JUST becomming available to order on their main site sometime today.
I saw no indication of Wifi support, same as on the S5. Wifi is such a limited market, I suspect they decided it wasn't worth the cost.
