Key Features of the Antminer KS3
High Hashrate for Maximum Mining Efficiency
The Antminer KS3 delivers a powerful 8.3 terahashes per second (8.3Th/s) hashrate, positioning it among the top-tier mining rigs for KHeavyHash-based cryptocurrencies. This level of performance enables faster block validation and increased mining rewards, especially in networks where computational power directly influences profitability.
A higher hashrate not only improves your chances of earning block rewards but also enhances overall mining competitiveness—critical in today’s saturated mining landscape.

Optimized for the KHeavyHash Algorithm
As the first ASIC miner from Bitmain built specifically for the KHeavyHash algorithm, the KS3 fills a unique niche in the market. KHeavyHash is designed to be ASIC-friendly while maintaining resistance to GPU and CPU dominance, ensuring fairer mining distribution and long-term network security.
This optimization allows the KS3 to outperform general-purpose miners on compatible blockchains, offering superior efficiency and lower operational friction.
Energy Efficiency That Cuts Costs
Despite its high output, the KS3 maintains a power consumption of 3188 watts, delivering a competitive energy efficiency ratio. In an industry where electricity costs can make or break profitability, the KS3’s balance between power draw and performance is a major advantage.
For miners operating at scale or in regions with higher energy rates, this efficiency translates into meaningful cost savings over time—boosting net profits without sacrificing output.
Robust Hardware and Cooling Design
Industrial-Grade Build Quality
Weighing 16.1 kg and measuring 195 x 290 x 430mm, the Antminer KS3 is built for durability. Its industrial-grade chassis and internal components are designed to withstand continuous operation in demanding environments, from home setups to large-scale data centers.
The use of high-quality ASIC chips ensures stable performance and longevity, reducing downtime and maintenance needs.
Advanced Dual-Fan Cooling System
Heat management is critical in mining hardware. The KS3 features a dual-fan cooling system combined with strategically placed heat sinks to efficiently dissipate heat. This design maintains optimal internal temperatures even under full load, preventing thermal throttling and hardware degradation.
With a noise level of 75dB, the KS3 operates at a level comparable to urban traffic—acceptable for industrial settings but best suited for dedicated mining spaces rather than quiet residential areas.
User-Friendly Operation and Remote Management
Intuitive Web-Based Interface
Setting up and managing the Antminer KS3 is straightforward thanks to its user-friendly web interface. Through a simple IP login, users can configure mining pools, monitor real-time performance, adjust fan speeds, and view power consumption metrics.
No advanced technical skills are required, making it accessible even for those new to ASIC mining.
Remote Monitoring and Control
Equipped with RJ45 Ethernet (10/100M) connectivity, the KS3 supports remote access from any device with a browser. Whether you're managing a single unit or an entire farm, you can monitor uptime, troubleshoot issues, and optimize settings from anywhere in the world.
This feature is especially valuable for distributed mining operations or users who prefer automated, hands-off management.

Frequently Asked Questions (FAQ)
Q: Is the Antminer KS3 suitable for home mining?
A: While possible, the KS3’s 75dB noise level and high power draw make it better suited for garages, basements, or dedicated mining facilities. Proper ventilation and electrical setup are essential.
Q: Does the KS3 come with a power supply unit (PSU)?
A: No, the Antminer KS3 does not include a PSU. You’ll need to purchase a compatible 200–240V power supply separately to ensure stable operation.
Q: How do I calculate profitability with the KS3?
A: Use online mining calculators that factor in hashrate (8.3Th/s), power consumption (3188W), local electricity rates, and current coin value. Network difficulty and pool fees also impact returns.
Q: Can I mine Bitcoin with the Antminer KS3?
A: No. The KS3 uses the KHeavyHash algorithm and is not compatible with Bitcoin’s SHA-256 algorithm. It’s designed exclusively for KHeavyHash-based cryptocurrencies.
Q: What is the expected lifespan of the Antminer KS3?
A: With proper cooling, stable power, and regular maintenance, ASIC miners like the KS3 typically last 3–5 years. Performance may degrade over time due to component wear.
Q: Where can I buy the Antminer KS3 securely?
A: Purchase from authorized distributors or trusted platforms to avoid counterfeit units. Always verify warranty terms and after-sales support.
