All About BTC, LTC, ETH mining as well as other alternative crypto currencies
BitMain has listed the upcoming ~500 GHS AntMiner S3 Bitcoin ASIC miner on their website based on the new 28nm BM1382 chips that were recently announced. The AntMiner S3 should start shipping from July 10th with a price set at 0.75 BTC, so you can already pre-order your unit if you are interested. The initial effective hash rate for the S2 was announced to be 504 GHS plus/minus 5% and now it seem that Bitmain has lowered it a bit to 478 GHS, though the unit should be overclockable to 500 GHS or more. The power consumption for the 500 GHS hashrate that was previously announced was 390W on wall and now with the official hashrate lowered a bit the power usage is also a bit lower at 366 Watt.
AntMner S3 Final 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
Do note that the BitMain AntMiner S3 ships without a PSU. There are 4 PCI-e connectors for +12V DC input, but it apparently needs only two of them to be connected if you are not going to be overclocking the device, so the other two are required only if you do plan to overclock the device.
