Hello Community,

Finally, we can make a promise now. We will open the sales of S3 in the Beijing Time tonight 22:00. Beijing is in the UCT+8:00 Time Zone.

The price will be 0.75 BTC per unit in the first. The first batch of S3 will be shipped between the July 10th and 20th.

We strongly believe it is best choice of mining bitcoin for both the mining farm and the home miners.

AntMiner S3 is the third generation Bitcoin mining rig made by Bitmain. It uses the state of the art BM1382 chip powered by the 28nm tech process with ultra-low power consumption, targeting the best combination of power efficiency and low capital expenditure for mining investors.

Specifications

Hash Rate: 478 GH/s±5%
Power Consumption: 366 Watt at the wall
Power Efficiency: 0.77 J/GH on wall
Power Supply: 12V DC
Size: 331 mm x 137 mm x 160 mm
Fans: Two 14038 fans mounted on both front and back ends.
Operating Temperature: 0 °C to 35 °C
Complied with: FCC / CE
Network Connection: Ethernet

Features

1.   Stand alone: The S3 mines stand alone, needs no proxy server.
2.   Quiet: The customized heat sinks mounted to the hash boards, one box over S3 to control the air flow, two fans mounted on both front and back ends that mean fans are able to work at lower speed to dissipate all heat easily. This design let S3 run at much lower noise level.
3.   Stable: Running 24 hours a day with minimal downtime.
4.   Accurate: Hardware Error got from the sample unit rate is as low as 0.3%, which is the lowest in the world.
5.   Efficient: High energy efficiency to save your investment on PSU and electricity bills.

Notes

1.   Power consumption: This figure depends on the PSU efficiency, ambient temperature and the accuracy of the power meters.
2.   PSU: You have to prepare your own the ATX PSU. The S3 ships without a PSU. There are 4 PCI-e connectors for +12V DC input, but it only needs to connect two of them. Dont parallel connected DC inputs from different PSU into the same Hashing board.

thinking about this i can see i might need more psu's . now i know why i was holding back .
