ElphaPex DG1 Profitability — LTC+DOGE Merged Mining
Is the ElphaPex DG1 profitable?
The base DG1: 11 GH/s at 3,420 W (approx. manufacturer spec), ~0.31 J/MH. ElphaPex is Bitmain's most serious Scrypt competitor of the current generation, and the DG1 is its L7-class entry — the same power envelope as an L7, roughly 15% more hashrate.
The only honest answer is a live one: revenue moves with LTC and DOGE prices and network hashrate every day. Its case is simple: L7-class output without the Bitmain brand premium on the used market — run both pages at your tariff and let the break-even rows argue. 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 — 11 GH/s | 11 GH/s · 3,420 W · 0.31 J/MH |
| Input power | 200–240 V dedicated circuit |
| Current draw | ≈14.9 A at 230 V |
| Heat output | ≈11,669 BTU/hr (3,420 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.
