Powerful Bitcoin Mining Performance with Antminer S21+
The Antminer S21+ is an upgraded version of Bitmain’s S21 series, launched in February 2025. It offers enhanced mining power with a hashrate ranging from 216 TH/s up to 235 TH/s, depending on the specific model configuration. This strength makes it a reliable choice for miners aiming for higher output without excessive power consumption. The miner consumes approximately 3564 watts, delivering an energy efficiency of 16.5 J/TH. This balance provides good performance while controlling electricity costs, which is vital for both small- and large-scale mining operations.
Efficient Cooling and Compact Design
The S21+ features a compact body measuring 400 x 195 x 290 mm and weighs around 15.4 kg, making it easy to fit into a variety of mining setups. It uses four high-speed fans that provide effective air cooling, ensuring the device remains at optimal running temperature during continuous 24/7 mining cycles. Despite its power, the noise level remains around 76 dB, which is manageable for industrial mining farms with proper sound insulation. The device is designed to operate efficiently within ambient temperatures of 0 to 45°C and humidity levels between 10% and 90%, making it adaptable to diverse mining environments.
User-Friendly Features and Stable Operation
The Antminer S21+ offers stable performance with easy network connectivity through an RJ45 Ethernet port, allowing users to remotely monitor and manage the device. Bitmain provides ongoing firmware updates to improve performance, security, and overall stability. A 12-month warranty accompanies the miner, which supports peace of mind for buyers. Compared to the standard S21 model, the S21+ provides a noticeable performance boost with better efficiency, making it the ideal middle ground for miners who want something more powerful before moving to the Pro models. Overall, the S21+ delivers a combination of power, efficiency, and reliability suited for serious cryptocurrency miners in 2025.
