AFRNDK Antminer S15 28Th/s SHA-256 ASIC mining hardware

SKU CH-JTBW-H814B

SHA-256 ASIC miner delivering 28 Th/s at 1596 W with 57 J/T efficiency using 7 nm BM1391BE chips

Options S15

  • 28 Th/s peak hash rate for high Bitcoin mining throughput
  • 57 J/T power efficiency at 25 °C lowers electricity cost per terahash
  • 7 nm BM1391BE chip packs dense transistor count for strong performance
  • 1596 W draw in high-performance mode matches 25 Th/s output
  • All-in-one chassis with four hash boards simplifies setup and maintenance

Antminer S15 28Th/s SHA-256 ASIC Miner

The AFRNDK Antminer S15 is a Bitmain-built SHA-256 ASIC miner rated at 28Th/s maximum hash rate. It uses 288 BM1391BE 7nm chips across four hash boards in an all-in-one chassis with integrated power supply.

Suited for SHA-256 mining operations

This unit targets operators running Bitcoin or SHA-256 pools who want 7nm efficiency at 57 J/T in high-performance mode. The 76db noise level and 1596W draw make it unsuitable for quiet or power-constrained sites.

28Th/s hash rate with 57 J/T efficiency

The decisive spec is the 28Th/s peak throughput at 57 J/T power efficiency under 25°C conditions. That ratio determines whether the rig meets your cost-per-threshold for SHA-256 mining.

Highlights

  • 28 Th/s peak hash rate for high Bitcoin mining throughput
  • 57 J/T power efficiency at 25 °C lowers electricity cost per terahash
  • 7 nm BM1391BE chip packs dense transistor count for strong performance
  • 1596 W draw in high-performance mode matches 25 Th/s output
  • All-in-one chassis with four hash boards simplifies setup and maintenance

Questions about this item

What does 28 Th/s mean for daily Bitcoin output?

28 Th/s is the nominal hash rate; actual daily Bitcoin earnings depend on network difficulty, pool fees and electricity cost, so the figure alone does not guarantee a fixed return.

How does the 57 J/T efficiency translate to wall power?

At 25 °C the High-Performance mode draws 1596 W for 25 Th/s, giving 57 J/T; power will vary with temperature and voltage supply.

What clearance does the 176 x 221 x 279 mm unit need for airflow?

The miner uses one-side intake and exhaust fans rated at 76 dB; allow several centimetres on intake and exhaust sides for unrestricted airflow.
