Why Choose the Antminer S19?
The Antminer S19 series has become a benchmark in the Bitcoin mining world due to its proven reliability and consistent output. With the S19 95T model, Bitmain delivers a machine optimized for efficiency and durability, making it ideal for miners who prioritize stable performance over time.
High Hashrate, Controlled Power Draw
Delivering 95 TH/s, this miner competes well against newer models while consuming a manageable 3,250 watts under standard conditions. This balance ensures that even with moderate electricity rates, users can maintain positive daily profitability.
Built for the Long Haul
Constructed with industrial-grade components and advanced cooling systems, the S19 is designed to operate continuously in well-ventilated environments. Its robust build quality contributes to a longer operational lifespan—especially when maintained properly.
Mine Multiple SHA-256 Coins
While primarily used for Bitcoin mining, the Antminer S19 also supports other cryptocurrencies using the SHA-256 algorithm, including:
- Bitcoin Cash (BCH)
- Bitcoin SV (BSV)
This flexibility allows miners to switch between coins based on profitability and network difficulty without changing hardware.
Mining Profitability Overview
At current market conditions (as of 2025), the Antminer S19 95T generates approximately $2.29 in daily profit, assuming average electricity costs and network difficulty. However, actual earnings vary depending on:
- Local electricity rates
- Bitcoin price fluctuations
- Mining pool fees
- Network hash rate competition
💡 Pro Tip: Use online mining calculators to estimate your ROI based on real-time data from your region.
Despite these variables, the S19 remains one of the more resilient models in terms of return on investment (ROI), with an estimated payback period of 360 days or more, depending on operational costs.

Frequently Asked Questions (FAQs)
What is the expected lifespan of the Antminer S19?
With proper maintenance and optimal operating conditions—such as controlled temperature, low dust exposure, and stable power—the Antminer S19 can last 3 to 5 years. Regular cleaning and firmware updates help extend its usable life.
How do electricity costs affect mining profitability?
Electricity cost is the largest ongoing expense in mining. High energy prices can quickly erode profits. For example, at $0.10/kWh, the S19 remains profitable; however, above $0.15/kWh, ROI timelines extend significantly. Always calculate break-even points before deployment.
Can I use third-party firmware on the Antminer S19?
Yes, some miners use custom firmware like Braiins OS+ or Vnish to improve efficiency or unlock features. However, doing so may void warranties and carries risks if not installed correctly.
Is the power supply unit included with the miner?
Yes, the Antminer S19 95T comes with a compatible PSU (e.g., APW12), ensuring plug-and-play readiness upon arrival.
What mining pools are compatible with the S19?
The S19 works with any SHA-256 mining pool, including:
- F2Pool
- Poolin
- Slush Pool
- BTC.com
Choose a pool based on fee structure, payout method, and server location for best results.
How noisy is the Antminer S19?
The unit produces approximately 75 dB of noise—similar to a vacuum cleaner. It’s recommended to house it in a dedicated space away from living areas or use sound-dampening enclosures.
Final Thoughts: Is the Antminer S19 Still Worth It in 2025?
