Whether you're scaling up a professional mining farm or entering the space with serious intent, the Antminer KS3 offers a compelling blend of performance, durability, and ease of use.
Key Features of the Antminer KS3
High Hashrate Performance
At its core, the Antminer KS3 delivers a peak hashrate of 8.3 TH/s, positioning it as one of the most powerful miners in its category. This level of computational output significantly increases block-solving probability, directly impacting revenue potential—especially in networks where mining difficulty continues to rise.
For operators managing large-scale rigs, this consistent performance translates into predictable daily yields and improved return on investment (ROI) over time.
Optimized for KHeavyHash Algorithm
The KS3 is the first Bitmain miner designed specifically for the KHeavyHash algorithm. This optimization ensures full compatibility and peak efficiency when mining supported cryptocurrencies. Unlike general-purpose miners that may require firmware tweaks or suffer from suboptimal performance, the KS3 runs natively on KHeavyHash, reducing latency and maximizing throughput.
This specialization makes it an ideal long-term asset for miners focusing on chains adopting this algorithm.
Energy Efficiency and Power Consumption
Power efficiency is critical to profitability in crypto mining, and the KS3 strikes a smart balance. It consumes 3,188 watts under full load while operating within a standard voltage range of 200–240V. Its energy efficiency ratio sits at approximately 384 J/TH, which is competitive given its high-output design.
When paired with low-cost electricity or renewable energy sources, the KS3 becomes even more financially viable, especially in regions with favorable power rates.
Durable Hardware and Industrial Design
Built for continuous operation, the KS3 features a rugged industrial chassis measuring 195 x 290 x 430 mm and weighing 16.1 kg (without packaging). The unit integrates high-quality ASIC chips engineered for longevity and thermal resilience.
Its dual-fan cooling system, combined with strategically placed heat sinks, ensures stable internal temperatures even during extended mining cycles. This robust thermal management helps prevent overheating and extends the lifespan of internal components.
Advanced Cooling and Noise Management
Despite its high power output, the KS3 maintains an operational noise level of 75 dB, comparable to a loud conversation or urban traffic. While not silent, this is considered moderate for industrial-grade miners.
The dual-fan setup provides dynamic airflow control, adjusting speed based on real-time temperature feedback. This adaptive cooling enhances reliability in environments where ambient temperatures fluctuate between 5°C and 40°C, which is the recommended operating range.
Humidity tolerance spans from 10% to 90%, allowing deployment in diverse geographic locations without requiring extreme environmental controls.
User-Friendly Interface and Remote Management
Setting up and managing the KS3 is straightforward thanks to its intuitive web-based interface. Through an RJ45 Ethernet (10/100M) connection, users can access the miner’s dashboard from any device on the same network.
Key functions include:
- Real-time monitoring of hashrate and temperature
- Fan speed adjustments
- Power status tracking
- Firmware updates
- Pool configuration and failover settings
Remote access enables miners to manage their operations from anywhere in the world—ideal for distributed mining farms or cloud-managed setups.
