ElphaPex DG2 PLUS (20.5GH)

20.5 GH/s Scrypt at 3,900W continuous and 0.19 J/MH (190 J/GH) efficiency. ElphaPex's ±3 percent hashrate tolerance produces real world output between 19.9 and 21.1 GH/s. ±10 percent power tolerance means real world draw runs between 3,510 and 4,290W.

DG2 at 16 GH/s, 3,520W, and 0.22 J/MH. DG2+ at 20.5 GH/s, 3,900W, and 0.19 J/MH. The DG2+ delivers approximately 28 percent more hashrate at approximately 11 percent more power draw and approximately 14 percent better efficiency per megahash. Same chassis and cooling architecture with better binned chips, similar to the Bitmain L11 / L11 Pro relationship. The DG2 and DG2+ are interchangeable in any deployment, allowing fleet operators to mix both tiers to optimize capital and efficiency.

All Scrypt algorithm cryptocurrencies through merged mining. Primary coins: Litecoin (LTC), Dogecoin (DOGE), Bellscoin (BELLS). Additional supported coins per ElphaPex documentation: Luckycoin (LKY), Pepecoin (PEP), DogeMemecoin (DOGM), EarthCoin (EAC) through compatible pools. Combined merged mining revenue typically runs 20 to 40 percent above solo LTC at the same hashrate.

Depends on voltage, noise, and thermal capacity. Voltage: requires 200 to 240V with 32A max current split across two AC input wires. Cannot run at 110V residential. Noise: 75 dB industrial exceeds comfortable household levels and requires dedicated mining space. Thermal: 3,900W requires ventilation or HVAC. For quiet home Scrypt mining at smaller scale, ElphaPex's own DGHome 2.1G variant or Fluminer L3 (9.5 GH/s, 45 dB) and Fluminer L1 Pro (6 GH/s, 45 dB) are appropriate.

200 to 240V single phase AC input with 32A maximum current distributed across two AC input wires each rated for 16A. 47 to 63Hz frequency range. The dual AC input wire configuration differs from typical single cord deployments and requires specific power infrastructure planning. Cannot run at 110V residential since 3,900W at 120V would require approximately 32.5 amps, above standard residential circuits. Standard commercial 220 to 240V service works with appropriate dual input configuration.

Four cooling fans with front intake and rear exhaust airflow direction. No external water loops or immersion. Facility requirements: ventilation for approximately 13,310 BTU per hour heat output, adequate intake and exhaust air, ambient temperature within the specified range. Internal temperature sensors manage fan RPM and hashrate throttling under thermal stress. Recommended altitude below 2,000 meters for reliable operation.

MillionMiner lists 369 x 196 x 287 mm chassis at 16.5 kg. ElphaPex official documentation lists 432.8 x 196 x 287 mm at 18.3 kg net weight (21.6 kg gross shipping weight), reflecting a 63 mm length and 1.8 kg weight discrepancy versus the MM specification. Verify actual chassis dimensions with MillionMiner before rack planning or logistics preparation.

5 to 45 degrees Celsius at 5 to 95 percent humidity per MillionMiner specification. For hot climate deployments (UAE, Texas summer, Arizona, tropical regions), facility cooling must hold intake air below 40 degrees Celsius under peak load for stable hashrate.

6 month ElphaPex factory warranty on new units covering manufacturing defects and hardware failures under normal operation within specified environmental ranges. Ships from MillionMiner with free DDP worldwide delivery covering all customs clearance, import duties, and taxes. Box contents: ElphaPex DG2+ unit, PSU, power cables, and quick start guide.

L11 Pro at 21 GH/s, 3,612W, and 0.172 J/MH. DG2+ at 20.5 GH/s, 3,900W, and 0.19 J/MH. The L11 Pro delivers approximately 2 percent more hashrate at 7 percent less power draw and approximately 10 percent better efficiency per megahash. Voltage range is broader on the L11 Pro (100 to 240V PSU input tolerance, though practical deployment at 220V+) versus DG2+ 200 to 240V. Ecosystem maturity favors Bitmain (broader operator familiarity, deeper third party firmware support). For operators with L11 Pro inventory access, the L11 Pro is the spec leader. For operators seeking vendor diversification or during L11 Pro supply constraints, the DG2+ is the alternative.

VolcMiner D3 at 20 GH/s, 3,580W, and 0.179 J/MH. DG2+ at 20.5 GH/s, 3,900W, and 0.19 J/MH. The D3 delivers slightly less hashrate at 320W less power draw and approximately 6 percent better efficiency per megahash. Voltage range is wider on the D3 (200 to 300V versus 200 to 240V). Both are newer manufacturer alternatives to Bitmain with similar ecosystem maturity levels. For operators choosing between non Bitmain Scrypt hardware, the D3 generally offers better efficiency while the DG2+ offers slightly higher hashrate per unit with expanded coin support.

SEALMINER DL1 Air at 25 GH/s, 3,725W, and 0.149 J/GH delivers 22 percent more hashrate and approximately 22 percent better efficiency per gigahash than the DG2+. Bitdeer (NASDAQ: BTDR) provides stronger manufacturer stability than ElphaPex's smaller operation. For operators choosing between non Bitmain Scrypt hardware, the DL1 Air offers significantly better per unit economics. The DG2+ competitive position rests on availability scenarios and expanded merged mining coin support rather than efficiency leadership.

75 dB industrial noise from four cooling fans at peak operation. Comparable to a vacuum cleaner or busy restaurant. Disruptive through walls. Requires sound isolated deployment space: dedicated mining room, garage, outbuilding, warehouse, or commercial facility. Not suitable for residential proximity without sound containment.

Third party firmware support for ElphaPex hardware is limited compared to the Bitmain ecosystem. Most DG2+ operators run stock ElphaPex firmware. BraiinsOS style tuning has not targeted ElphaPex specifically. Operators relying on firmware tuning for efficiency optimization should plan for stock ElphaPex firmware operation.

Four step setup with attention to dual AC input configuration. Verify 200 to 240V single phase circuit capable of 3,900W continuous with appropriate dual AC input wiring (each wire rated 16A, 32A combined max). Connect PSU to miner using both AC input wires to the supply. Connect Ethernet cable to router or switch. Find miner IP via router admin or IP scanner tool, open ElphaPex web interface, configure Scrypt merged mining pool URL and LTC/DOGE/BELLS wallet addresses, change default credentials. Verify hashrate reaches 19.5+ GH/s within 10 minutes.

Major Scrypt merged mining pools accept DG2+ hashrate including F2Pool, Poolin, ViaBTC, Prohashing, Litecoinpool. Pool fees typically 0.5 to 2 percent. The DG2+ is configured for expanded merged mining support: LTC, DOGE, BELLS, LKY, PEP, DOGM, EAC per ElphaPex documentation. Pool support for the smaller coins (DogeMemecoin, EarthCoin) is limited, verify specific pool coin lists before deployment.

Yes. MillionMiner hosting services accept DG2+ units at managed facilities with appropriate 200 to 240V single phase infrastructure supporting dual AC input wire configuration. Contact MillionMiner for hosting rate tiers and availability.

L9 at 17 GH/s, 3,570W, and 0.21 J/MH. DG2+ at 20.5 GH/s, 3,900W, and 0.19 J/MH. The DG2+ delivers approximately 21 percent more hashrate at approximately 9 percent more power draw and approximately 10 percent better efficiency per megahash. For L9 operators at current conditions, the DG2+ delivers better hashrate and efficiency at the cost of moving away from Bitmain's ecosystem to a newer manufacturer with less established support history.

Mixed assessment. Pro factors: alternative to Bitmain's dominance at the 20+ GH/s Scrypt tier, expanded merged mining coin support (LTC, DOGE, BELLS, LKY, PEP, DOGM, EAC), flagship ElphaPex standalone tier, 6 month manufacturer warranty, DG2 and DG2+ fleet mixing flexibility. Con factors: L11 Pro delivers better spec leadership (hashrate, efficiency, voltage range), VolcMiner D3 delivers better efficiency at similar manufacturer maturity tier, Bitdeer SEALMINER DL1 Air delivers significantly better per unit economics, dual AC input wire configuration requires specific power infrastructure. For operators prioritizing vendor diversification or expanded merged mining coin exposure, the DG2+ delivers competitive positioning. For operators optimizing for pure per unit economics, alternatives offer better returns.
