Antminer S21 Pro: compare the selected variant
The Bitmain Antminer S21 Pro is an air-cooled SHA-256 ASIC for Bitcoin mining. This listing offers 234T and 245T options. The manufacturer reference below describes the 234T configuration; do not apply its power figures automatically to the 245T option.
| Reference configuration | S21 Pro 234T |
|---|---|
| Algorithm | SHA-256 / BTC, BCH |
| Typical hashrate | 234 TH/s ±3% |
| Wall power at 25°C | 3510 W ±5% |
| Efficiency at 25°C | 15 J/TH ±5% |
| Input voltage | 220–277 V AC |
| Network | RJ45 Ethernet 10/100M |
Plan power, ventilation and noise
BITMAIN lists 76 dBA at 25°C. This is equipment for a dedicated, ventilated environment, not a quiet living space. Have a qualified installer check the circuit, connector, protective devices and heat exhaust for the selected unit.
234T or 245T?
Request the batch sheet and model label matching your order. Compare hashrate and wall power under the same conditions, rather than assuming the higher hashrate uses the same electricity. Compare the S21 XP separately; it is a different model.
What affects operating cost?
Use measured power, electricity rate, cooling and service charges. Pool fees, network difficulty, downtime and coin price also change results; this page does not promise mining income or payback.
Request an equipment or hosting quote
Send the selected variant, quantity, equipment condition, delivery destination and planned installation date. Ask for an itemized offer covering accessories, delivery, warranty and any hosting setup or recurring service charges. Availability and commercial terms must be confirmed in writing; a quote request is not a reservation.
