Bitmain Antminer S9 (Used)
The Antminer S9 respects the same form factor as the very popular Antminer S7 and its size is almost identical. Yet, it has more than three times the power and double efficiency of the S7. The BM1387 chip from Bitmain is built with TSMC’s FinFET 16 nm technology and delivers a record of 0.098 J/GH. You look at one of the best-selling bitcoin miners in the world, the Antminer S9. This miner has a hashrate between 12.9TH/s and 14.5TH/s. Carrying 189 BM1387 chips, the S9 was the most energy efficient bitcoin miner of its time. Even in 2019, at least half of Bitcoin’s mining operation is with Antminer S9, which has not been upgraded to ASICboost. All our miners will be delivered with ASICboost firmware update installed. We can also install BraiinsOS on demand because this miner is compatible with the open-source operating system. The Antminer S9 is probably one of the least expensive mining equipment available to start Bitcoin mining, while generating a return on investment in some places with cheap energy excess. Once you have accessed the Antminer UI, you only need to enter your Wallet address and Pool settings before you start mining.
