ElphaPex DG1+ Profitability — LTC+DOGE Merged Mining
Is the ElphaPex DG1+ profitable?
ElphaPex's 14 GH/s challenger to the Antminer line at 3,920 W (approx. manufacturer spec), ~0.28 J/MH — between the L7 and L9 on efficiency, at the highest wall draw in the scrypt preset table. The open question on challenger brands is support and resale, not the spec sheet; the math below is the same either way.
The only honest answer is a live one: revenue moves with LTC and DOGE prices and network hashrate every day. It pulls more wall power than anything else on this list — at 3,920 W the circuit question comes before the profitability question, and the spec table below answers both. The break-even electricity figure is the line — pay less per kWh than that and the machine earns, pay more and it burns.
Why both coins count
Every serious Scrypt profitability number counts both reward streams. Through AuxPoW merged mining, the same hashes earn full Litecoin and full Dogecoin block rewards on one power bill — LTC-only math understates ElphaPex DG1+ revenue by the entire DOGE share. The mechanics are on our LTC+DOGE merged mining calculator, which this page's math mirrors exactly.
Specs & physical reality
| Spec | Value |
|---|---|
| Factory bin — 14 GH/s | 14 GH/s · 3,920 W · 0.28 J/MH |
| Input power | 200–240 V dedicated circuit |
| Current draw | ≈17.0 A at 230 V |
| Heat output | ≈13,375 BTU/hr (3,920 W — all of it becomes room heat) |
| Noise | ≈75 dB (manufacturer claim) — server-fan loud, not for living spaces |
| Warranty | varies by brand, seller and region — get the term in writing before paying; used units typically carry none |
| Spec source | ElphaPex — approx. manufacturer figures; real units vary by bin, firmware and temperature |
FAQ
- Does the ElphaPex DG1+ mine LTC and DOGE at the same time?
- Yes — Scrypt machines merge-mine. The same proof of work is submitted to both chains, earning full rewards on each. Most major LTC pools credit DOGE automatically alongside LTC.
- What does the revenue figure exclude?
- Transaction fees on both chains (small next to subsidies, so figures are slightly conservative), cooling power, and difficulty drift. The 2027 Litecoin halving is a scheduled cut, not drift — the payback tile flags it when your horizon crosses it.
