ANTMINER S7 is available at bitmaintech.com
with BM1385 chips, 4.86TH/S, 0.25J/GH

only available at bitmaintech.com


Sales will be open at 9pm(UTC+8), August 30th, 2015
 
                                  
Bitmain is pleased to introduce our latest machine, the Antminer S7. This powerful machine features a small form factor, like our previous Antminer S5, while utilizing the denser hash board arrangement of the more recent S5+. This is the first Bitmain product to use our recently announced BM1385 chip, which is not only more than twice as power efficient as the BM1384 chip before it, but is also the most power efficient chip available to consumers today.


The Antminer S7 has a more dense configuration than previous Antminer machines, using 162 chips in the same space that the S5 used only 60 in. The S7 uses just 1,210 watts of electricity to deliver a whopping 4.86 terahashes per second of pure mining power.

S7 Specifications:
  • Hash Rate: 4.86 TH/s ±5%
  • Power Consumption: 1210 W (at the wall, with AC/DC APW3, 93% efficiency, 25C ambient temp)
  • Power Efficiency: 0.25 J/GH (at the wall, with AC/DC APW3, 93% efficiency, 25°C ambient temp)
  • Rated Voltage: 12V+5%, should not be less than 12.0V
  • Chip quantity per unit: 162x BM1385
  • Dimensions: 301mm(L)*123mm(W)*155mm(H)
  • Cooling: 2x 12038 fan
  • Operating Temperature: 0 °C to 40 °C
  • Network Connection: Ethernet

Notes:
1.   Power consumption figures will vary with your PSU’s efficiency, the ambient operating temperature and the accuracy of the power meter.
2.   PSU: A power supply unit is not included, and you will need to provide an ATX PSU. There are 3 PCI-e connectors for +12V DC input on each hashing board and all 3 are required.Do not connect more than one PSU to the same hashing board!
3. Separate power supply to control board: there is one additional 6pin PCI-e connector on the IO board which must be connected to the PSU to get power. If you use different PSU for hash boards and control board, please make sure to power the hash boards first and the control board only after the hash boards have been powered.


This machine is not only our most efficient ever, using less than half the energy per gigahash of the S5, but it is also our most powerful miner to enter mass production (the S5+ had a higher hashrate but was sold on a limited basis). At 0.25 joules per gigahash, this is the most efficient machine available to the bitcoin mining public.

A New Cooling Solution:
As S5+, the S7 also uses an unpainted aluminum casing, each chip is fitted with its own small heatsink for greater heat dissipation.
S7 contains two 12038 axial fans, one on each end. Each fan runs at approximately 4,200 RPM.

good I have just enough coins ready for one.

I will do a nice long review of it. On my dime since my power rates will drop on October 1st I can mine this until the spring before I sell it.

I am looking forward to it.

Lol that's either extreme dedication to bitcoin checking forums at the mall or you're stuck waiting for the significant other.  Cheesy

Hope not.  That's quite pricey.  Although, I paid 4.92BTC for an S1. Roll Eyes

S5+ make a lot of sense now. S7 looks to have the same chassis, virtually the same chip layout and power connections, and same controller card.
