Bitmain Antminer S21+ Bitcoin Miner

Engineered for high-performance mining, the Bitmain Antminer S21+ achieves a powerful hash rate of 216 Th/s, positioning it as a highly efficient solution for SHA-256/Bitcoin mining operations

To sustain its high-performance output of 216 Th/s, the Bitmain Antminer S21+ operates at a power consumption of 3564W.

The air-cooling system in the Antminer S21+ produces a 76dB noise level, a key factor to consider for placement in home or office settings.

For shipping and setup planning: the Antminer S21+ has a net weight of 21.5 kg and a gross shipping weight of 24.5 kg, ensuring stability and easy handling.

The Antminer S21+ is engineered for the SHA-256 algorithm, specializing in Bitcoin mining.

Designed for flexible deployment, the Antminer S21+ supports a wide input voltage range (220-277V) to match standard mining infrastructure.

With compact dimensions of 450 x 219 x 293 mm, the Antminer S21+ is designed to integrate seamlessly into space-limited mining setups without performance compromise.

Bitmain provides a comprehensive 365-day manufacturer warranty for the Antminer S21+, ensuring protection against manufacturing defects and hardware malfunctions.

For peak performance and long-term reliability, the Antminer S21+ should be operated within its ideal temperature range of -20°C to 45°C. Consistently running outside this range may reduce mining efficiency and shorten the hardware’s operational life.

The primary factors influencing ASIC miner lifespan include operating temperature control, cooling system efficiency (e.g., hydro/immersion vs. air cooling), power supply stability, and consistent maintenance. Units operating in stable, cool environments with advanced cooling solutions generally achieve significantly longer service life compared to air-cooled models subjected to dusty and high-temperature conditions.

When choosing an ASIC miner, prioritize hashrate (computational speed), energy efficiency (measured in J/Th or J/Mh), and your local electricity costs. The optimal miner is one that strikes a balance across these three factors to ensure long-term profitability.
