The Bitmain Antminer S21 Pro (234Th) is a SHA-256 ASIC miner designed for Bitcoin mining, delivering a confirmed hash rate of 234 Th/s with a power draw of 3510W at 15 J/Th efficiency. It operates on a voltage range of 220 to 277V AC and includes integrated air-cooling fans for sustained performance under load. The unit is built with proprietary Bitmain ASIC chips and a reinforced PCB layout to handle continuous operation in industrial environments.
The miner uses standard 16nm or 7nm ASIC silicon technology, typical for mid-2024 high-efficiency Bitcoin miners. Cooling is managed by four 120mm fans with variable speed control, a common design in enterprise-grade units. The power supply unit is external and compatible with standard 208V to 277V three-phase inputs, aligning with global mining farm electrical standards. No internal battery or backup systems are included, as is typical for fixed-installation mining hardware.
This miner is purchased primarily by cryptocurrency mining farms, data center operators, and institutional investors scaling Bitcoin production. Buyers typically order in batches of 10 or more units to benefit from bulk logistics. Trade terms are commonly FOB Guangzhou or CIF port of destination, with payment via T/T. Minimum order quantities are not stated in the listing and must be confirmed directly with the supplier. Lead times vary based on inventory and export documentation readiness.

Before placing an order, verify the authenticity of the ASIC chips and confirm the unit has not been previously deployed or modified. Request a serial number list and photos of each unit's label matching the batch number. Ensure the supplier can provide a proof of purchase from Bitmain or an authorized distributor, as counterfeit units are common in this market.
Confirm the Incoterms, shipping method, and insurance coverage with the supplier. FOB Guangzhou is typical, meaning risk transfers at the port of loading. Lead time is usually 15 to 30 days after payment, depending on export clearance. Payment terms are commonly 30% advance, 70% before shipment via T/T. Avoid L/C unless the supplier has a proven track record with it.
Perform a visual inspection upon arrival for physical damage, missing fans, or tampered seals. Test each unit for 72 hours under load using a mining pool to confirm hash rate stability. Request a test report showing power consumption per Th/s and temperature logs. Ensure all documentation, including export declaration and compliance certificates, is provided before customs clearance.
