The Sealminer A2 from Bitdeer has a hashrate of 230Th and a power consumption of 3795W mining Bitcoin (BTC).

Bitdeer’s Sealminer A2 represents the latest generation of ASIC Bitcoin miners, purpose-built for high efficiency and robust performance in industrial-scale cryptocurrency mining. Bitdeer outfits the Sealminer A2 with the advanced SEAL02 chip, which leverages a 4nm process. As a result, the device achieves a maximum hashrate of 230 terahashes per second (TH/s) while consuming approximately 3,795 watts. Consequently, the A2 delivers an impressive energy efficiency of 16.5 joules per terahash (J/TH). This combination places the A2 among the most efficient air-cooled miners available for SHA-256 cryptocurrencies, including Bitcoin, Bitcoin Cash, and Bitcoin SV.

Furthermore, the Sealminer A2 relies on four high-performance fans to manage heat, which ensures stable operation even in demanding environments. Bitdeer designs the A2 to function reliably across a temperature range of 0 to 40°C and at altitudes up to 2,000 meters. Therefore, users can deploy the A2 in a variety of mining farm conditions. The device produces a noise output of 75 decibels, a level typical for high-powered mining equipment, which makes it suitable for dedicated mining facilities rather than residential spaces.

When it comes to connectivity, the Sealminer A2 features a standard Ethernet interface (10/100M), which allows for seamless integration into existing mining operations. Bitdeer includes the power supply unit (PSU) with the miner. However, the device requires an input voltage of 220-277V, so it does not support standard household 110-120V outlets. This requirement clearly demonstrates its focus on industrial and large-scale mining environments.
Moreover, Bitdeer emphasizes durability and reliability in the A2’s design. The miner withstands storage temperatures ranging from -20°C to 70°C and operates effectively in humidity levels between 20% and 80% (non-condensing).

Ultimately, the Sealminer A2 distinguishes itself by balancing a high hashrate with energy efficiency. This makes it a compelling choice for miners who prioritize operational cost-effectiveness and consistent performance. As a result, the A2 establishes itself as a top contender for professional mining operations aiming to maximize profitability in the rapidly evolving Bitcoin mining landscape.
