Antminer T21

Description

High-Performance Bitcoin Mining with Antminer T21
The Antminer T21 by Bitmain is a powerful ASIC miner released in early 2024, designed for the SHA-256 algorithm. It delivers a strong hashrate of 190 TH/s while consuming about 3610 watts of power. This translates into a solid energy efficiency of 19 J/TH. Tailored for mining Bitcoin (BTC), Bitcoin Cash (BCH), and Bitcoin SV (BSV), the T21 offers a good balance between performance and power consumption. Its mining capabilities make it well suited for both professional mining farms and advanced enthusiasts aiming for high output with stable performance.

Efficient Cooling and Durable Construction
This model features an air-cooling system with four fans — two intake fans on the front and two exhaust fans at the back — ensuring optimal airflow and effective heat dissipation. It maintains stable operation even during continuous 24/7 mining sessions. The miner’s dimensions are 400 x 195 x 290 mm with a weight of 16.4 kg, making it easy to fit into existing mining rack setups. Despite the powerful cooling, the noise level stays around 75 decibels, typical for industrial miners. The T21 is designed to operate effectively between 0 to 45°C with a wide humidity range, allowing it to adapt to different environmental conditions.

Network Connectivity and User-Friendly Features
The Antminer T21 supports an RJ45 Ethernet port with 10/100M network speed, allowing stable and secure remote management and monitoring. Bitmain provides firmware updates to boost performance, enhance security, and fix bugs, ensuring the device runs optimally throughout its lifespan. With a three-phase power supply requirement of 380 to 415 volts, it guarantees stable energy delivery and allows users to operate at higher overclocking settings if desired. Its modular design simplifies maintenance, reducing downtime, while its robust build assures reliability and longevity over extended use.
