Bitmain Antminer S9 (Used)
Each Antminer S9 uses 189 BM1387 chips to offer more hashrate and efficiency than most other Bitcoin miners on the market. The BM1387 chip from Bitmain is built with TSMC’s 16-nm FinFET. The Antminer S9 follows a size factor similar to that of the previously popular Antminer S7. All of our Antminer S9 will ship with ASICboost and have been carefully optimized to deliver an average efficiency of 80W/TH, compared to a stock efficiency of 97W/TH, which gives your Bitcoin miner a 23% efficiency boost!
