I'll wait for lower prices, for me it is too high,

[neegeeboo]

Must have one...

Guys, can you use two 750W PSU to power this miner ?

[carlosmnk]

not at all

You need 410w at the wall for each hashboard, from ONLY one PSU...

Well you could use different PSU's for different hashing boards.  I would prefer one though.

Biggest thing is not to mix psu's on hashing board. IE one hashing board and two PSU's going to it.

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!

wow this seems very powerful and also most power efficient miner in the market ...
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.

[elrippo]

Nice, i hope to get one soon

@Bitmain: Will you offer this one at DHGATE.com also? Does it run on WIFI?

 I remember seeing something SOMEWHERE about "4200 rpm" fans, which makes them probably the same Delta model that is used on the S5.

 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.

Does anybody know the power draw and CFM? Or even better, a data sheet?

 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.


 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.

[Searing]

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

only 25W for 190CFM?...

• 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?

[This is ambient temp, not reported chip temp]

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 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?

[mavericklm]

because they are 25mm fans in the 38mm frame

that's why the screaming noise!

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.

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

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

This says it all

WAY OVERPRICED.

Who are you with, I'm on 8p/KWh (0.12$/KWh).
