Overview
This used Antminer S21 offers the 200 TH/s configuration with nominal power consumption of 3500 W. It suits buyers with an existing mining installation who want to add Bitcoin capacity and can assess used hardware before deployment.
Plan the installation around continuous electrical load, clear intake airflow and an unobstructed exhaust path. Allocate a dedicated operating area where fan noise and heat will not disturb occupied rooms.
Before purchase, ask us for current operating results, cosmetic condition, repair history and the included cable set. Model ratings do not establish the measured performance or remaining service life of an individual used machine.

Bitmain Antminer S21 200T Used: Purchase and Setup FAQs
The configuration is rated at 200 TH/s and 3500 W. These are nominal model figures, not a test certificate for an individual used unit. Ask us for current operating results before purchase.
Ask us about hashboard operation, fan condition, repair history, cosmetic wear, included accessories and warranty coverage. Used condition alone does not mean the machine has been refurbished or has remaining factory warranty.
No. It requires 220–277 V AC. Have the circuit, grounding, connectors and power distribution checked for continuous mining use before installation.
At a constant 3500 W, it uses approximately 84 kWh over 24 hours, excluding external ventilation and other equipment. Multiply 84 by your electricity price per kWh to estimate daily miner electricity cost.
Its cooling fans and continuous heat output make a dedicated mining area more practical. Keep the intake and exhaust clear, and assess how noise and hot exhaust will affect neighboring spaces.
Connect the miner to your wired network, then configure your chosen pool address and worker details in its management interface. Check that all hashboards operate normally and that the pool receives accepted shares after startup.
