Description

Antminer T21

Are you looking for a reliable and efficient Bitcoin miner for modern mining operations? The Antminer T21 from Bitmain is a high-performance SHA-256 ASIC miner designed to deliver strong hashing power while maintaining solid energy efficiency for professional mining farms.

The Antminer T21 operates on the SHA-256 algorithm, making it suitable for mining Bitcoin (BTC) and other SHA-256 cryptocurrencies such as Bitcoin Cash (BCH) and Bitcoin SV (BSV). This miner delivers a maximum hashrate of about 190 TH/s while consuming approximately 3610W of power, resulting in an efficiency of around 19 J/TH.

Built with Bitmain’s advanced ASIC architecture, the T21 provides strong and stable performance for industrial mining environments. With 190 TH/s hashing power and around 3.6 kW power consumption, the miner offers a balanced combination of computing performance and electricity efficiency compared to earlier generations.

The Antminer T21 uses a high-performance air-cooling system with multiple fans to maintain stable temperatures during continuous mining workloads. It typically operates with a noise level around 75 dB, making it suitable for professional mining facilities or well-ventilated environments.

The unit measures approximately 400 × 195 × 290 mm, weighs around 16 kg, and connects through a standard RJ45 Ethernet interface for network communication and remote management. It typically requires 380–415V power input and is designed to operate reliably in environments with temperatures between 0°C and 45°C.

With 190 TH/s SHA-256 hashing power, 3610W power consumption, and efficient ASIC technology, the Antminer T21 provides a powerful and dependable solution for modern Bitcoin mining operations that require stable performance and optimized energy usage.
