ElphaPex, sometimes stylized as Alphapex, is one of the newest names in the world of cryptocurrency mining hardware. Backed by FoundationLogic, the company has quickly positioned itself as a serious player in the Scrypt mining sector, focusing on Litecoin (LTC) and Dogecoin (DOGE). Their DG-series ASICs bring together cutting-edge performance and carefully engineered energy efficiency.

Unlike older manufacturers, ElphaPex has emphasized both hashrate per watt and thermal design innovations, making their machines stand out in the highly competitive ASIC market. From compact units like the DG Home 1 to powerhouse rigs such as the DG2+, the lineup covers a broad spectrum of needs  but always with an emphasis on mining efficiency.

DG1 and DG1+: The First Generation

The DG1 was ElphaPex’s entry into the market, offering around 11 GH/s at 3.42 kW with an efficiency of about 0.31 J/MH. Equipped with four high-speed fans, it was a straightforward workhorse for Scrypt mining.

The upgraded DG1+ improved performance significantly, reaching 14.4 GH/s at 3.95 kW, pushing efficiency closer to 0.27 J/MH. This represented a ~30% increase in hashrate with only a modest increase in power, proving that ElphaPex could deliver noticeable performance gains in a short development cycle.

• DG1: 11 GH/s, 3420 W, ~0.31 J/MH

• DG1+: 14.4 GH/s, 3950 W, ~0.27 J/MH

Both models showed that ElphaPex was serious about entering the ASIC game, establishing a baseline for efficiency and reliability.

DG2 and DG2+: The Performance Flagships

With the DG2 series, ElphaPex pushed Scrypt mining into new territory.

The DG2 delivers 18 GH/s at around 3.96 kW, with an efficiency of ~0.22 J/MH. Already this was a huge leap forward from the DG1 line.

But the DG2+ set a new standard: 20.5 GH/s at 3.90 kW, achieving an impressive ~0.19 J/MH. This makes it one of the most efficient Scrypt ASICs on the market today.

• DG2: 18 GH/s, 3960 W, ~0.22 J/MH

• DG2+: 20.5 GH/s, 3900 W, ~0.19 J/MH

The DG2+ not only improved hashrate but also squeezed more performance out of every watt consumed, reducing heat and increasing long-term sustainability.

DG Hydro 1: Innovation Through Liquid Cooling

One of the most interesting developments from ElphaPex is the DG Hydro 1. Unlike traditional air-cooled miners, this model uses liquid cooling to keep temperatures stable.

Specs:

• Hashrate: 20 GH/s

• Power: 6200 W

• Efficiency: ~0.31 J/MH

While its efficiency matches older air-cooled designs, the Hydro 1’s advantage lies in heat management. By moving to water-based cooling, the machine can sustain heavy workloads with less noise and better temperature stability. This makes it well-suited for dense mining setups where airflow is limited and heat buildup is a serious issue.

DG Home 1: Compact but Efficient

At the smaller end of the lineup, the DG Home 1 offers 2.1 GH/s at 630 W, with an efficiency of ~0.30 J/MH.

Despite being compact, it maintains similar efficiency to larger models, showing ElphaPex’s ability to scale its chip technology down effectively. While it doesn’t match the industrial-scale output of the DG2+, it demonstrates how the company’s ASIC architecture adapts across different product classes.

Efficiency Gains Across Generations

Looking at the DG lineup as a whole, there’s a clear trajectory:

• DG1: ~0.31 J/MH

• DG1+: ~0.27 J/MH

• DG2: ~0.22 J/MH

• DG2+: ~0.19 J/MH

This progression highlights ElphaPex’s engineering focus on performance per watt. Each generation reduces the energy required to produce a megahash, directly improving profitability for miners.

Even the Hydro 1, while not the most efficient, represents an innovation in cooling design  a signal that ElphaPex is experimenting with new approaches to thermal management.

Conclusion

ElphaPex’s DG-series shows how quickly a newcomer can make waves in the ASIC mining industry. From the first DG1 to the advanced DG2+, the company has proven its ability to iterate rapidly, delivering higher hashrates and better efficiency with each generation.

The introduction of the Hydro 1 shows that ElphaPex is not only focused on efficiency but also exploring alternative cooling strategies that could shape the future of mining. With steady improvements in J/MH and a strong lineup of models, ElphaPex has secured its position as a serious competitor in the world of Scrypt mining.

For miners focused on Litecoin and Dogecoin, the DG-series represents a new era of efficient, high-performance ASICs with ElphaPex leading the charge.
