How to Set Up Bitmain Antminer S19k Pro (120TH/s, 2760W) SHA-256 Bitcoin Miner

The Bitmain Antminer S19k Pro is a high-performance SHA-256 ASIC miner delivering 120TH/s hash rate while consuming 2760W of power. This miner is designed for professional and serious home miners, offering high efficiency, reliability, and long-term stability.

This step-by-step guide covers unboxing, installation, configuration, and optimization to get your S19k Pro running safely and profitably.

1. Required Tools and Preparations

Before starting, ensure you have:

  • Bitmain Antminer S19k Pro unit

  • Compatible power supply unit (PSU) with at least 2760W capacity

  • Stable internet connection (Ethernet recommended)

  • Mining pool account (e.g., Antpool, F2Pool, Foundry USA, ViaBTC)

  • Computer or mobile device for configuration

  • Adequate ventilation for cooling the miner and PSU

  • Surge protector or UPS to prevent electrical hazards

⚠️ The S19k Pro is a high-power device; ensure your power circuit can safely handle 2760W.

2. Unboxing and Inspection

  1. Carefully unbox the miner.

  2. Inspect the miner for physical damage, such as bent fins, broken connectors, or loose fans.

  3. Ensure that all accessories (power cables, screws, manual) are included.

  4. Place the miner on a stable, flat surface with good airflow around it.

3. Connecting the Power Supply

  1. Connect the PSU to the miner’s power input ports.

  2. Ensure the PSU supports 2760W continuous output at 220–240V.

  3. Connect the PSU to a stable electrical outlet, ideally on a dedicated circuit.

  4. Confirm proper grounding to prevent electrical hazards.

💡 Tip: Use a UPS or surge protector to prevent downtime or damage during power surges.

4. Network Connection

  1. Connect the miner to your router or switch using a reliable Ethernet cable.

  2. Avoid using Wi-Fi, as mining requires a stable connection.

  3. Make sure your router supports DHCP, so the miner can automatically obtain an IP address.

5. Accessing the Miner Interface

  1. Locate the miner’s IP using your router’s admin panel or Bitmain IP Reporter tool.

  2. Enter the IP address in a web browser.

  3. Log in using the default credentials:

    • Username: root

    • Password: root

  4. Navigate to the Miner Configuration section.

6. Mining Pool Configuration

  1. Under Pool Settings, input your mining pool URL(s).

    • Example for Antpool: stratum+tcp://btc.antpool.com:3333

  2. Enter your Worker Name (usually walletaddress.workername).

  3. Enter a password if required (often “x”).

  4. Save the settings and apply changes.

The miner will start hashing and submitting shares to your pool.

7. Monitoring Miner Performance

  1. Check the Miner Status page for:

    • Hashrate (should be near 120TH/s)

    • Fan speeds

    • Temperature readings

    • Accepted/rejected shares

  2. Adjust cooling and airflow if temperatures are too high.

  3. Enable automatic restart in case of power or network failure.

8. Firmware Updates

  • Check Bitmain’s website regularly for firmware updates.

  • Update firmware via the System tab in the miner’s interface.

  • Firmware updates improve efficiency, security, and stability.

9. Safety and Maintenance

  • Keep the miner in a cool, dry, dust-free area.

  • Ensure fans have unobstructed airflow.

  • Periodically check power connections and cables.

  • Avoid overloading the electrical circuit; consider separate circuits for multiple miners.

10. Troubleshooting

  • Miner not starting: Check PSU wattage and connections.

  • Low hashrate: Verify pool settings, internet stability, and firmware version.

  • Overheating: Improve airflow and clean dust from fans.

  • Network issues: Use IP Reporter to reconnect the miner.

Conclusion

The Bitmain Antminer S19k Pro is a high-efficiency SHA-256 miner ideal for serious Bitcoin mining operations. Proper setup, cooling, and monitoring are essential to maximize performance and ensure long-term reliability.

Following this guide ensures your miner will operate at 120TH/s efficiently, minimizing downtime and maximizing profitability.
