Antminer KS3 Overview

The Antminer KS3 is a Bitmain ASIC miner released in August 2023 for the KHeavyHash algorithm. It is primarily designed to mine Kaspa, also known as KAS.

With a maximum hashrate of 9.4TH/s, the Antminer KS3 delivers strong algorithm-specific mining power for Kaspa mining operations. Its rated power consumption is approximately 3500W ±10% at 25°C.

The miner uses four cooling fans to remove heat from the hashboards and internal components. It connects through RJ45 Ethernet 10/100M, which is preferred for stable mining-pool communication and consistent uptime.

Because the Antminer KS3 produces approximately 75–76dB of noise and consumes around 3.5kW of power, it is best suited for dedicated mining rooms, warehouses, hosting facilities and professional ASIC mining farms.

Antminer KS3 Specifications

Technical values can vary slightly according to manufacturing batch, operating temperature, power quality, firmware, airflow and miner condition.

Review the official Bitmain KS3 specifications before installation.

Antminer KS3 KHeavyHash Mining Performance

The Antminer KS3 provides up to 9.4TH/s of KHeavyHash computing power. This makes it significantly stronger than compact home-oriented Kaspa miners, although it also requires much more electricity, airflow and noise control.

Hashrate measures the amount of mining work the machine can perform. A higher hashrate can increase the miner’s proportional contribution to a mining pool, but hashrate alone does not guarantee profit.

Actual pool-side performance may vary because of firmware, operating temperature, power quality, pool latency, rejected shares and equipment condition. Operators should monitor accepted shares, rejected shares, miner temperature, fan speed and average hashrate regularly.

The Antminer KS3 is purpose-built for KHeavyHash mining. It is not designed for Bitcoin mining because Bitcoin uses SHA-256, and it is not a Litecoin or Dogecoin miner because those coins use Scrypt.

Power Consumption and Energy Efficiency

The Antminer KS3 consumes approximately 3500W during rated operation. This equals 3.5 kilowatts of continuous electrical demand, with a listed tolerance of ±10% at 25°C.

When operating continuously for 24 hours:

3.5kW × 24 hours = 84kWh per day

At an electricity rate of $0.10 per kWh:

84kWh × $0.10 = approximately $8.40 per day

These estimates cover only the listed miner power draw. They do not include external ventilation, air conditioning, networking equipment, power-distribution losses, mining-pool fees, hosting charges, shipping costs or repair expenses.

The Antminer KS3 has a listed power efficiency of 0.37 J/Ksol ±10% at 25°C. Buyers should still calculate facility-level costs because cooling and power infrastructure can increase the real operating expense.

Antminer KS3 Profitability

Antminer KS3 profitability depends on Kaspa mining revenue minus electricity, pool fees, cooling, hosting, maintenance and hardware costs. The miner does not produce fixed income because KAS price, KHeavyHash difficulty and total network hashrate change regularly.

Important profitability factors include:

• Kaspa market value: The value of KAS affects the fiat value of mining rewards.
• KHeavyHash network difficulty: Higher difficulty may reduce the amount earned by the same 9.4TH/s hashrate.
• Electricity cost: Power is normally the largest recurring mining expense.
• Mining-pool fees: Pool fees reduce gross mining income.
• Pool payout method: Payout structure can affect reward consistency.
• Cooling cost: Ventilation and heat management may add extra electricity use.
• Hardware price: Purchase cost affects the estimated payback period.
• Miner uptime: Downtime reduces valid work submitted to the pool.
• Maintenance cost: Fans, power supplies and hashboards may require service.
• Shipping and duties: Import charges can increase the delivered cost.

To estimate net income, subtract electricity, pool, cooling, hosting and maintenance costs from projected mining revenue. Then compare the net daily result with the hardware purchase price to estimate a simple payback period.

Any ROI estimate for the Antminer KS3 should be updated regularly and treated as a projection rather than guaranteed profit.

Cooling, Heat and Noise Management

The Antminer KS3 uses four high-speed cooling fans to move air through the miner and remove heat from the hashboards. Proper airflow is essential because most of the miner’s electrical consumption becomes heat during operation.

With an approximate noise level of 75–76dB, the miner produces industrial-level sound. It is usually better suited for mining rooms, warehouses, hosting centers and ventilated enclosures than bedrooms or shared offices.

Recommended cooling practices include:

• Provide unrestricted cool-air intake
• Direct hot exhaust away from the miner
• Prevent exhaust air from returning to the intake
• Operate within the recommended 0°C to 40°C range
• Keep humidity within the recommended 10% to 90% range
• Keep ventilation paths free from dust
• Inspect all four fans regularly
• Use alerts for overheating and hashrate loss
• Maintain stable electrical power

Do not place the miner inside a sealed soundproof enclosure without professionally engineered airflow. Restricted ventilation can cause overheating, unstable hashrate and premature hardware failure.
