Bitmain Antminer KS5 Pro 21TH/s – Kaspa KHeavyHash ASIC Miner

The Bitmain Antminer KS5 Pro delivers a maximum hashrate of 21 TH/s on the kHeavyHash algorithm used by the Kaspa network, with a wall power consumption of approximately 3150 watts at 25 degrees Celsius. This positions the Antminer KS5 Pro 21TH as one of the most powerful dedicated Kaspa ASIC miners on the market. The KS5 Pro power draw translates to an efficiency of roughly 150 joules per terahash, which helps keep electricity costs manageable for both home miners and large-scale operations. Whether you want to buy the Bitmain Antminer KS5 Pro for personal mining or commercial deployment, its balance of hashrate and wattage makes it a top choice for Kaspa mining.

Given its high power draw and thermal output, you need proper power Installing the Bitmain Antminer KS5 Pro requires a dedicated 220-240 V electrical circuit rated for at least 16 amps, as the miner draws approximately 3150 watts during normal operation. The KS5 Pro generates considerable heat and noise from its built-in cooling fans, so it should be placed in a well-ventilated space such as a garage, warehouse, or purpose-built mining room. A stable Ethernet connection is required to connect the miner to a Kaspa mining pool through the web-based configuration interface. Ambient temperature should remain below 40 degrees Celsius to avoid thermal throttling. Proper electrical grounding and surge protection are also strongly recommended for the Antminer KS5 Pro.

It was released around early 2024 (March 2024), positioning it as a next-The Bitmain Antminer KS5 Pro was released in early 2024 as a significant upgrade over the earlier Antminer KS3, which delivered 9.4 TH/s on kHeavyHash. The KS5 Pro more than doubles that hashrate to 21 TH/s while maintaining a competitive efficiency of roughly 150 J/TH. Compared to other Kaspa ASIC miners on the market, the Antminer KS5 Pro 21TH offers one of the best combinations of raw performance and energy efficiency. Bitmain's proven reliability and firmware support also give the KS5 Pro an edge for operators who need stable, long-running hardware in professional Kaspa mining facilities.

It uses the kHeavyHash algorithm and is designed for mining Kaspa The Antminer KS5 Pro runs the kHeavyHash algorithm, which is the proof-of-work consensus mechanism used by the Kaspa blockchain. This means the KS5 Pro Kaspa miner is purpose-built to mine KAS coins exclusively and cannot be used for Bitcoin or other SHA-256 cryptocurrencies. Kaspa is known for its blockDAG architecture and rapid block times, making it one of the fastest-growing proof-of-work networks. The Bitmain Antminer KS5 Pro delivers 21 terahashes per second on kHeavyHash, giving miners a significant advantage over GPU-based Kaspa mining setups. As Kaspa adoption grows, dedicated ASIC hardware like the KS5 Pro becomes essential for competitive mining.

The unit has an efficiency of approximately 150 J/TH under standard The Bitmain Antminer KS5 Pro achieves an energy efficiency of approximately 150 joules per terahash, making it one of the most power-efficient Kaspa ASIC miners available. With a total power draw of around 3150 watts, the KS5 Pro consumes roughly 75.6 kWh per day. At an electricity rate of 0.10 USD per kWh, the daily power cost is about 7.56 dollars, which is manageable given the strong Kaspa mining rewards the Antminer KS5 Pro 21TH can generate. Keeping the miner in a cool, well-ventilated environment helps maintain peak efficiency and reduces the risk of thermal throttling over extended operation periods.
