Innovative Operating Modes for Maximum ROI

The standout feature of the Antminer T21 is its ability to adapt to your specific mining conditions. It supports two distinct operating modes:

  • Normal Mode: Delivers 190 TH/s at a power efficiency of 19 J/TH, perfect for balancing hashrate with electrical costs.

  • High Energy Mode: Allows the miner to push performance even further in regions with low electricity costs or during peak market conditions.

Built for Extreme Environments

Unlike many miners that struggle in warmer climates, the T21 is designed with enhanced thermal tolerance. Its advanced air-cooling system ensures the ASIC chips remain at optimal temperatures even in environments up to 45°C.

  • Quad-Fan Design: Four high-velocity 12038 fans provide a consistent air tunnel to dissipate heat rapidly.

  • Integrated APW PSU: The built-in power supply is tuned for efficiency and protection against voltage fluctuations, ensuring long-term hardware health.

  • Industrial Build Quality: The aluminum housing provides excellent heat dissipation and physical protection for the high-density hash boards.
