Product Details

ביטמיין אנטר miner S21 195TH קירור באויר מכשיר להחליק את הביטקוין פלטפורמת יסוד

Pay attention to the voltage: 12V DC. Most Bitmain Antminers accept AC power directly. The S21 at 195 TH/s on 12V requires a separate high amperage power supply unit that converts AC to 12V DC. This adds cost, weight, and a failure point. Factor the PSU into both your budget and your deployment planning.

195 TH/s at 3,400W makes this the base S21, sitting below the S21+ at 235 TH/s and the S21 PRO at 234 TH/s. The S21 generation bridged the gap between the S19 era (95 to 151 TH/s) and the S23 generation (318 TH/s). Efficiency at roughly 17.4 J/TH is mid tier by current standards.

Daily electricity at $0.07 per kWh: $5.71. Monthly: $171. The 12V DC quirk means you also need a PSU capable of sustaining 3,400W continuously at 12V, which means roughly 283 amps. APW12 or equivalent Bitmain PSU. These run $100 to $300+ depending on source. Not included with the miner.

75 dB standard industrial. Ethernet. Bitmain Antminer firmware with full fleet management ecosystem. Third party firmware like Braiins OS likely available for S21 models, offering potential efficiency optimization through autotuning.

For fleet buyers, the 12V DC version of the S21 sometimes appears at lower acquisition cost than the AC versions precisely because the PSU requirement discourages casual buyers. If you already operate 12V infrastructure or can source PSUs cheaply, this pricing gap becomes an arbitrage opportunity.

Antminer S21 195TH Foundation Air Cooled Bitcoin Miner

Original Bitmain S21 at 195 TH/s and 3,400W. The model that defined the S21 generation before the S21+, S21 XP, and S23 followed. Now two generations behind the S23 (318 TH/s). Available at significant discount. 12V DC input.

Air cooled at 75 dB. Bitcoin, Bitcoin Cash, all SHA 256. Bitmain firmware. 195 x 290 x 370mm at 13.2 kg. Ethernet. 5 - 35 °C.

Industrial 75 dB requires dedicated mining space. Warehouses, containers, or isolated rooms. Not for shared environments.

Bitmain firmware for pool configuration and monitoring. Evaluate pricing against competing models at this tier.

Industrial noise at 75 dB demands purpose built mining space. Warehouses, shipping containers, dedicated rooms with sound treatment, or hosting facilities. Plan for noise management in any deployment. 3400W of heat output also requires adequate ventilation or HVAC capacity to maintain operating temperatures.

Evaluate per terahash acquisition cost and daily electricity at your rate. Total fleet hashrate determines total coins mined. Model conservatively with current network data.
