Real-Time Mining Profitability (2025)
As of mid-2025, the Antminer S19 Pro generates approximately:
- Daily Income: $8.20 in Bitcoin value
- Daily Electricity Cost: -$7.80 (based on $0.10/kWh)
- Net Daily Profit: $0.4033
- Monthly Profit: $12.10
- Annual Profit: $147.19
These figures reflect current network difficulty, BTC price averages, and standard energy costs. While daily profits may seem modest, cumulative returns over time—especially during bull market cycles—can justify the initial hardware investment.
Keep in mind that electricity cost is the largest variable impacting profitability. Miners operating in regions with subsidized or renewable energy (e.g., hydro, solar) often see significantly improved margins.
Technical Specifications Overview
Understanding the core specs helps assess whether the S19 Pro fits your infrastructure and goals.
Hashrate
The Antminer S19 Pro delivers a maximum hashrate of 110 TH/s (terahashes per second) using the SHA-256 algorithm. This places it among the top-tier ASIC miners at launch, though newer models have since surpassed it.
Power Consumption
With a rated power draw of 3,250 watts, this unit demands a robust electrical setup. It's crucial to ensure your circuit can handle sustained loads without overheating or tripping breakers—especially when deploying multiple units.
Energy Efficiency
One of the S19 Pro’s standout features is its efficiency rating of 29.55 joules per terahash (J/TH). This means it uses 29.55 joules of electricity to produce one terahash of computational work. For context:
- Below 30 J/TH is considered highly efficient for SHA-256 mining.
- Older models like the S9 exceed 100 J/TH, making them obsolete in most markets.

- Interface: Ethernet for configuration and monitoring
- First Batch Released: May 2020
- Announcement Date: April 2020
Mineable Cryptocurrencies
While primarily used for Bitcoin (BTC) mining, the S19 Pro supports any cryptocurrency utilizing the SHA-256 consensus algorithm, including:
- Bitcoin Cash (BCH)
- Bitcoin SV (BSV)
- Peercoin (PPC)
- Mining via platforms like NiceHash, where SHA-256 hashing power is sold as a service
However, due to BTC’s dominance in network difficulty and market value, most operators focus exclusively on Bitcoin mining for optimal returns.
Performance & Longevity Insights
The S19 Pro was engineered as an upgrade to the S17 series, offering nearly double the hashrate with improved thermals and efficiency. Despite being released in 2020, many units remain operational in well-maintained facilities.
Key factors influencing lifespan:
- Regular dust cleaning and fan maintenance
- Stable ambient temperatures
- Consistent power supply (use of UPS or voltage regulators recommended)
With proper care, these miners can operate effectively for 3–5 years, though efficiency may degrade slightly over time.
Frequently Asked Questions
Is the Bitmain Antminer S19 Pro (110Th/s) still profitable in 2025?
Yes, but profitability depends heavily on electricity cost. At $0.10/kWh, it generates about **$0.40/day net profit**. In areas with cheaper power (<$0.06/kWh), returns improve significantly. Market conditions such as BTC price surges can also boost profitability during bull runs.
What is the hashrate of the Antminer S19 Pro?
It delivers up to 110 terahashes per second (TH/s) using the SHA-256 algorithm, making it suitable for Bitcoin mining.
How much electricity does the S19 Pro consume daily?
At 3,250W, it consumes approximately 78 kWh per day (3.25 kW × 24 hours). At $0.10/kWh, that equals **$7.80 in daily electricity costs**.
Can I mine Ethereum with the Antminer S19 Pro?
No. The S19 Pro uses SHA-256, while Ethereum relies on Ethash (now obsolete post-PoW) and currently operates on Proof-of-Stake. This miner is incompatible with Ethereum mining.
What cryptocurrencies can I mine with the S19 Pro?
You can mine any coin using the SHA-256 algorithm, including Bitcoin (BTC), Bitcoin Cash (BCH), and BSV. Many users also rent out their hashpower through platforms like NiceHash.
How noisy is the Antminer S19 Pro?
It produces around 75 decibels, similar to a running dishwasher or urban traffic. For home setups, consider placing it in a separate room or using acoustic enclosures.

Final Thoughts: Is the S19 Pro Still Worth It?
While newer models like the Antminer S19 XP and S21 offer higher efficiency and hashrates, the S19 Pro remains relevant—particularly for budget-conscious miners or those sourcing used units at discounted prices.
Its proven reliability, widespread community support, and compatibility with major mining pools make it a solid entry point into Bitcoin mining. However, always calculate your local electricity rate and cooling capacity before investing.
For those looking to scale or explore next-gen hardware, pairing legacy units like the S19 Pro with modern monitoring tools ensures maximum uptime and return on investment.
