DragonBall A21 (3.4GH/s) Hardware Overview

Learn more about this ASIC miner, including its specifications, performance, energy consumption, and profitability.

The DragonBall A21 arrives as a surgical instrument of mining, a machine-body that concentrates 3.4 GH/s of NexaPow computation into a deliberately engineered 16.1 kg frame (360 × 185 × 290 mm) and draws 1,800 W, achieving an energy efficiency of roughly 0.529 J/Mh; designed for the NexaPow algorithm and the Nexa cryptocurrency’s emphasis on scalability, security and decentralized finance, its optimized architecture prioritizes processing stability and balanced workload distribution so predictable throughput can be planned into professional installations and hosting farms. Its industrial-grade construction houses four high-speed cooling fans that function like lungs, expelling heat to sustain long runtimes within an ambient range of 5–40 °C, and it supports a broad input window of 160–300 V (with many deployments operating in the 220–277 V band) while interfacing over Ethernet for stable network connectivity; noise measures about 75 dB, typical for high-performance miners, and the overall package-robust chassis, effective thermal design and steady power draw-makes the A21 a pragmatic choice for operators seeking a resilient, efficient node in a larger rack-space ecology where machines occupy both a literal room and an abstract margin of alienation between human intention and automated computation.

DragonBall A21 In Detail

DragonBall A21 (3.4GH/s) — a closer look at the hardware and how it performs.

The DragonBall Miner A21 hums like a petition against entropy, a machine that delivers a steady 3.4 Gh/s of NexaPow hashing in a purposely restrained, industrial form. It pulls 1800 W and yields an energy efficiency near 0.529 J/Mh. Four high-speed cooling fans channel air through a rugged chassis and keep component temperatures stable during extended runs. That air-cooling strategy lowers downtime and extends hardware life. Built for the NexaPow algorithm, the A21 is aimed squarely at mining Nexa, a coin designed for scalability, security, and decentralized finance. Ethernet connectivity lets operators fold the unit into existing Nexa networks for centralized monitoring and straightforward management. The miner accepts 160–300 V input and operates reliably in ambient temperatures from 5 to 40 °C, which makes it adaptable to varied site conditions. Noise sits at about 75 dB, a normal level for performance-class miners. With its consistent hashrate, efficient power profile, and industrial-grade construction, the A21 supplies a pragmatic balance of performance and durability. It favors dependable throughput over spectacle and integrates cleanly into larger farm deployments. For operators planning capacity growth, the A21 stands as a resilient, efficient node that eases scaling and supports sustained Nexa mining operations.

Based on our real-time ASIC mining profit calculation, the DragonBall A21 is currently most profitable mining Nexa at your electricity rate of $0.080/kWh. This can change as coin prices and network difficulty shift, so check the Mineable Coins table above for the latest ranking.

This ASIC mining profit calculation for the DragonBall A21 uses live cryptocurrency prices, current network difficulty, and block rewards for every supported coin, combined with your custom electricity rate. Figures update automatically as network conditions change, so the profitability shown reflects current conditions rather than a static estimate.

NiceHash is a hashpower marketplace, not a traditional mining pool — instead of mining a coin directly, you sell your DragonBall A21 hashrate to buyers and get paid in Bitcoin. Compare the NiceHash row against direct-mining rows in the Mineable Coins table above: whichever shows the higher Profit/Day at your electricity rate is currently the better option for this specific miner.
