Bitmain Antminer S9i (14TH/s) Hardware Overview

Learn more about this ASIC miner, including its specifications, performance, energy consumption, and profitability.

The Bitmain Antminer S9i (14Th) stands as a stalwart workhorse for SHA‑256 mining, delivering a steady 14 TH/s while drawing 1,320 W, a balance of power and performance forged for long‑term operation; built around 189 BM1387 ASIC chips on 16 nm process, it achieves about 0.094 J/GH energy efficiency and reliably mines Bitcoin, Bitcoin Cash and Bitcoin SV with reduced downtime thanks to an optimized heat‑dissipation design and dual fans that temper its core, keeping thermal stability across an ambient range of 0°C to 40°C and humidity from 5% to 95%; compact and adaptable, it measures 350 mm × 135 mm × 158 mm and weighs 4.2 kg, fitting neatly into a variety of setups while offering the reliability and efficiency miners value, and operators can model expected returns and operating costs with a profit calculator that compares different electricity rates to show costs per day, month or year and help assess real‑time returns amid changing energy expenses and market conditions.

Bitmain Antminer S9i In Detail

Bitmain Antminer S9i (14TH/s) — a closer look at the hardware and how it performs.

The Bitmain Antminer S9i is a compact, no-nonsense SHA-256 miner built to run hard and run long: it pushes about 14 terahashes per second using 189 BM1387 ASICs on a 16 nm process, drawing roughly 1,320 watts and delivering near 0.094 J/GH efficiency, which makes it well suited to mine Bitcoin, Bitcoin Cash and Bitcoin SV; its thermal design pairs dual high‑RPM fans with aluminum heatsinks to evacuate heat quickly and maintain stable operation across ambient conditions of 0°C to 40°C and humidity from 5% to 95%, while improved power delivery reduces hash‑rate jitter and a firmware layer lets operators tune frequencies or apply conservative underclocking to trim consumption without sacrificing viable output in low‑cost energy environments. Robust and portable at 350 × 135 × 158 mm and 4.2 kg, the S9i fits into dense racks or home rigs, but to get the most from it deploy it in a ventilated, dust‑managed space, use a reliable, well‑sized power supply with clean voltage and surge protection, monitor temps and hash rates remotely, keep firmware backups and pool failover configured, and model operating scenarios with a return calculator that compares energy rates and pool fees so you can forecast performance and break‑even timelines without guesswork.

Algorithm Information: SHA-256

SHA-256 — what this algorithm is and how it works.

SHA-256 is a cryptographic hash function. Fractal Bitcoin relies on it for proof-of-work consensus. This algorithm processes input data of any length and produces a fixed hash value, ensuring security and integrity in the mining process.
