Detailed Review: ElphaPex DG2+ (20.5 GHz)

There are now more options in picking high-performance ASCIs, being that ElphaPex DG2+ has been introduced to Scrypt mining environments.

This device is designed for mining at an industrial level for Scrypt coins such as Litecoin, Dogecoin, and others, and also promises top-tier hashrate and energy efficiency in a heavy-duty build.

But how well does it perform, and is it worth its current price? Here’s a full hands-on review of the ElphaPex DG2+, based on a thorough overview of what top-ranking sources, vendors, and miners are saying.

Overview of ElphaPex DG2+

As of the time of this publication, DG2+ is ElphaPex’s most powerful Scrypt miner due to its massive 20.5Gh/s hashrate, which draws about 3900W of power.

These units, and it’s being large, loud, and designed for high-output mining operations, clearly show that it is built for serious miners.

In simple words, it is not something to run quietly at home. However, if you have access to cheap electricity and space to run noisy gear, the ElphaPex DG2+ is arguably one of the most profitable miners on the market.

Performance and Hashrate

This machine delivers exactly what it advertises; a stable 20.5Gh/s hashrate, with most users reporting minimal fluctuation even during long sessions.

And as such, it is being put far ahead of previous-generation Scrypt miners like the Goldshell LT6 or even Fluminer L1 Pro, making it one of the most efficient and powerful miners available today.

Real-time profitability reports show that it currently earns around $21 daily before electricity, depending on coin prices and network difficulty, also portraying its level of output as extremely appealing to miners looking to level up fast.

Power Consumption and Efficiency

At 3900W is the ElphaPex DG2+, and in return, you get a remarkable 0.19 J/MH energy efficiency, which is significantly better than many competing rigs and shows the improved hardware design that ElphaPex is starting to be known for.

Even with rising electricity costs, the ElphaPex DG2+ maintains solid daily earnings. For instance, at a power rate of $0.08/kWh, you could make a net profit of around $14.30/day, and even at $0.10/kWh, the unit still brings in $13.50/day.

This certainly adds up to over $400 per month in net earnings, making it one of the most profitable Scrypt miners running in 2025.

Cooling and Noise

To control its level of power, the ElphaPex DG2+ relies on four high-speed fans and a well-ventilated design. Well, that is as loud as expected, averaging 75 dB, being at the same level as a vacuum cleaner or heavy shop equipment.

This machine is built for garages, mining farms, or professional environments with good airflow. Although the cooling system handles the heat output, which is high, it is not a machine you want running near your living space.

Build Quality and Maintenance

Physically, the DG2+ is solid with a rugged industrial build with reinforced aluminum casing, weighing around 16.5 to 18.3kg. The airflow system is designed with fans that trap air across the chipboards.

It operates in environments from 5 to 45°C, with up to 95% humidity; in other words, it will not overheat even if performed in a range of setups.

As opposed to other machines, its Maintenance is straightforward; a regular dusting of the air vents and occasional checks for firmware updates. The user interface is web-based and easy to access through Ethernet to allow you to monitor your temperature, hashrate, uptime, and restart the machine remotely.

ROI and Profitability

At an average market price of $8,500 to $10,000, the ElphaPex DG2+ can not be said to be cheap, but the earnings are worth the investment. Currently, on the profits, the return on investment window is roughly 6 to 9 months, depending on power rates and coin market trends.

Compared to other ASICs in its class, it outpaces most in daily revenue and energy efficiency. On a long-term mining of Scrypt coins, this rig can pay itself off and keep producing profit for well beyond its ROI window.

Pool Compatibility and Usability

Unlike some locked-down ASICs, the ElphaPex DG2+ supports multiple mining pools, including F2Pool, ViaBTC, and others, giving miners more control and the ability to optimize payouts.

It also has firmware updates that are supported, and the interface allows remote monitoring and adjustments as needed.

Conclusion

The ElphaPex DG2+ is one of the most powerful Scrypt miners available in 2025, graded as an industrial machine made for farms or serious at-home operations with proper ventilation and noise isolation.

The DG2+ delivers exceptional daily profits and will likely remain competitive well into the next difficult cycle, just in case you are ready to invest in a high-performance unit and have the infrastructure to support it.

We give it 9.3/10 as an overall rating since it is best for professional miners, mining farms, Scrypt-focused operations, and not recommended for home users looking for low-noise or low-power setups.
