Purpose-built SHA-256 ASIC miner
The AFRNDK Bitmain Antminer S19 delivers a nominal 90 TH/s hashrate for Bitcoin, Bitcoin Cash and Bitcoin SV mining. It draws 3250 W at the wall with a rated efficiency of 36 J/TH, operating on 200–240 V AC input at 47–63 Hz. Four integrated fans produce 76 dB of noise while keeping the unit within its 0–40 °C operating range.
Power and connectivity constraints
The miner requires a 220 V supply; incorrect voltage can damage the hardware. Power tolerance is ±5 % on both consumption and efficiency figures, and hashrate varies by ±3 %. Network access is limited to a single RJ45 Ethernet port running at 10/100 Mbit/s, so upstream bandwidth above 100 Mbit/s cannot be used.
Upgrade path from earlier SHA-256 ASICs
Replacing older SHA-256 machines such as the T19 or S17 series raises hashrate per unit while improving energy efficiency toward the 36 J/TH mark. The jump is worthwhile when electricity cost per kilowatt-hour makes the efficiency gain large enough to offset the higher upfront capital outlay. Operators without 200–240 V infrastructure or adequate cooling for 76 dB noise should not deploy this model.

Questions sur cet article
Should I pick the 90 TH/s version or a different hashrate model?
The 90 TH/s model delivers 90 ±3% TH/s at 3250 ±5% W, yielding 36 ±5% J/TH efficiency. Lower-hashrate units such as the S17 series run at reduced throughput and different efficiency, while higher-hashrate variants draw more power and require matching cooling.
What does the 90 TH/s rating mean for daily Bitcoin output in a real setup?
At 90 ±3% TH/s and 3250 ±5% W wall power, the miner produces roughly 36 J/TH. Actual BTC earned depends on network difficulty, pool fees, and electricity cost; the hashrate figure sets the upper bound before those variables apply.
Does the RJ45 10/100M port limit mining performance?
The Ethernet link tops out at 100 Mbit/s, which is far above the few Mbit/s needed for stratum traffic, so the interface does not cap hashrate. Ensure the switch and cabling support 100 Mbit/s full duplex for stable connectivity.
