Bitmain Antminer T21

The Antminer T21, recently launched by Bitmain, is designed with a hashrate of 190 TH/s and an efficiency of 19 J/TH, making it suitable for high-performance mining operations, especially for Bitcoin and other SHA-256 coins. It operates at a power consumption of 3610W, and this model allows miners to choose between two energy modes: Normal Energy Mode (NEM) and High Energy Mode (HEM), with a peak performance option of up to 233 TH/s under HEM.

This unit is built for rigorous environments, tolerating operating temperatures up to 45°C with humidity levels of 10-90%. It’s encased within a structure that measures 400 x 212 x 290 mm and weighs 17 kg. The miner also incorporates a dual-fan cooling system, producing around 76 dBA of noise at maximum speed, which is typical for such high-powered devices
