The Bitmain Antminer S9 (13.5 TH/s) is a proven SHA-256 ASIC mining machine designed for Bitcoin mining. It delivers approximately 13.5 TH/s of hashrate (some units may be 14 TH/s) with a power consumption around 1320W.
This miner ships running Braiins OS (aftermarket firmware).
Braiins OS provides improved stability, tuning capability, and efficiency compared to stock firmware. A 1.8% development fee is built into the firmware. If you specifically require stock Bitmain firmware, please message us before purchase so we can accommodate your request.
Includes a genuine Bitmain APW3 power supply.
We have operated S9 miners since their original 2016 release and found them to be one of Bitmain’s most reliable and long-lasting platforms.
