Antminer S19j Specifications

Actual hashrate, wall power, operating temperature and noise may vary according to firmware, power quality, airflow, ambient conditions, miner condition and operating configuration.

Antminer S19j Mining Performance

The Antminer S19j delivers a maximum advertised hashrate of 90TH/s on the SHA-256 algorithm. Hashrate measures how many calculations the machine performs every second while processing mining work for Bitcoin and compatible networks.

A stable hashrate allows the Antminer S19j to contribute consistent mining power to a pool. However, hashrate alone does not guarantee profit. Electricity cost, Bitcoin price, mining difficulty, pool fees, machine price, cooling expenses and uptime must all be evaluated together.

Most operators connect the Antminer S19j to a professional Bitcoin mining pool instead of attempting solo mining. Mining pools combine hashrate from many miners and distribute rewards based on valid submitted work.

Mining pool selection can affect:

• Pool fees
• Payout frequency
• Rejected-share percentage
• Minimum payout limit
• Server location and latency
• Connection stability
• Payout method

Operators should monitor average hashrate, fan speed, temperature, rejected shares and pool connection status. Sudden performance drops may indicate restricted airflow, unstable electricity, network problems or hardware faults.

Power Consumption and Energy Efficiency

The Antminer S19j consumes approximately 3250W during operation. This equals 3.25 kilowatts of continuous electrical demand.

When operating continuously for 24 hours:

3.25kW × 24 hours = 78kWh per day

At an electricity rate of $0.10 per kWh:

78kWh × $0.10 = approximately $7.80 per day

These estimates cover only the listed miner power draw. They do not include external ventilation, air conditioning, transformers, networking equipment, mining pool fees, hosting charges or electrical conversion losses.

Based on 3250W and 90TH/s, the estimated efficiency of the Antminer S19j is approximately 36.1 J/TH. Buyers should compare total facility-level electricity cost before purchasing, because cooling and hosting can increase the real operating cost.

Antminer S19j Profitability

Antminer S19j profitability depends on Bitcoin mining revenue minus all operating expenses. The miner does not generate a fixed daily return because Bitcoin price, mining difficulty, network fees and total network hashrate change regularly.

Important profitability factors include:

• Bitcoin market price: The value of BTC affects the fiat value of mining rewards.
• Mining difficulty: Higher difficulty may reduce the amount earned by the same 90TH/s hashrate.
• Electricity cost: Power is usually the largest recurring mining expense.
• Mining pool fees: Pool charges reduce gross mining income.
• Cooling expenses: Ventilation and climate-control equipment may require extra electricity.
• Hosting charges: Professional facilities may charge monthly or per-kWh fees.
• Hardware price: Purchase cost affects the estimated payback period.
• Miner uptime: Downtime reduces valid work submitted to the pool.
• Maintenance costs: Fans, power supplies, controllers and hashboards may require service.

To estimate net income, subtract electricity, pool, cooling, hosting and maintenance costs from projected mining revenue. The hardware price can then be divided by estimated daily net income to calculate a simple payback period.

Any ROI estimate for the Antminer S19j should be updated regularly and treated as a projection rather than guaranteed profit.
