About the Bitmain Antminer S21+ (235TH/s)
Learn more about this ASIC miner, including its specifications, performance, energy consumption, and profitability.
The Bitmain Antminer S21+ (235Th) presents itself as a purpose-built instrument for the SHA-256 mines, delivering a raw hashrate of 235 terahashes per second while drawing roughly 3,877 watts and achieving an energy efficiency near 16.5 joules per terahash; its advanced firmware permits dynamic frequency scaling to adapt performance to power stability, and its robust industrial-grade construction and compact, user-friendly form factor make it suited to continuous 24/7 operation in diverse mining installations. Four high-speed fans and a refined air-cooling architecture keep operating temperatures in check and sustain consistent output, while a noise footprint around 75 decibels is to be expected from equipment of this capacity; the miner’s reliability and component quality support professional-scale deployments, and integration is eased by straightforward setup and management features. For operators seeking to project returns, a crypto-miner profit calculator can estimate potential earnings and electricity costs on daily, monthly, and yearly horizons based on chosen electricity rates and operational scenarios, helping to plan capacity, assess efficiency and weigh runtime trade-offs; in the quiet of a server room the S21+ hums like an apparatus engaged in an intellectual converse with an indifferent void, each hash a terse phrase in a dialogue between relentless computation and the yawning, pragmatic silence of power and profit.

The Antminer S21+ (235Th) arrives not as a toy but as a surgical instrument for SHA-256 mining, precise and unforgiving. It delivers 235 terahashes per second while drawing roughly 3,877 watts, yielding about 16.5 joules per terahash. At its core sits a 5 nm ASIC with proprietary chip optimizations that push hashing efficiency and cut waste heat. Firmware adds dynamic frequency scaling, which dials performance to match power stability or temperature limits. The chassis supports immersion cooling to dramatically lower junction temperatures and prolong component life in dense deployments. When air cooling is used, a refined architecture with four high-speed fans maintains steady thermal conditions. Industrial-grade components and a compact rack-friendly footprint make true 24/7 operation feasible. Expect a noise level near 75 dB, so plan acoustic isolation if humans work nearby. Remote management hooks into an AI-driven monitoring platform that provides real-time diagnostics, automated tuning, and fleet scheduling. Operators must design robust power distribution and targeted airflow because sustained hashing concentrates electrical and thermal stress. Regular firmware updates and preventive maintenance are non-negotiable to preserve efficiency and avoid abrupt failures. In short, the S21+ rewards those who treat deployment like clinical care: balance power, cooling, and service rhythm, and the machine will deliver steady throughput; neglect any of those, and the margins-and the hardware-suffer.
