Can you solo mine Zcash with a Innosilicon A9++ ZMaster?
Yes — a Innosilicon A9++ ZMaster (139.86 KH/s) can solo mine Zcash (ZEC) via a solo pool. At Zcash's 30.36 GH/s Equihash network that is about 2 blocks per year — expected one block roughly every 190 days, for the full 1.2500 ZEC (≈ 1,539 USD) block. BackPoW computes this from live network difficulty using a Poisson block-discovery model. Realistically this is genuinely worth a patient solo run.
Hardware Tier & Ecosystem Ranking on Zcash
The Innosilicon A9++ ZMaster is categorized in the Mid-Range Workhorse Tier (Middle quartile hashrate offering solid pool mining throughput with moderate solo variance.). Among all 14 tracked models on Zcash, it ranks #8 in electrical efficiency (90.23 H/W) and #7 in raw hashrate (139.86 KH/s).
Electricity Operating Costs & Breakeven
Running a Innosilicon A9++ ZMaster (1,550 W) pulls about 37.20 kWh per day (1132.3 kWh per month). At the standard rate of 0.069 USD/kWh, electricity costs roughly 2.57 USD per day (78.13 USD/month or 938 USD/year). Statistically that year returns 1.93 blocks, worth about $2,966 — expected revenue covers the power bill about 3.2x over.
The operational breakeven threshold is 0.218 USD/kWh. Expected net operating margin at benchmark tariffs:
- At 0.040 USD/kWh (Hydro / Renewable): +6.63 USD / day
- At 0.069 USD/kWh (Standard Industrial): +5.55 USD / day
- At 0.120 USD/kWh (Residential Grid): +3.66 USD / day
Break-even Coin Price Target: For this hardware to break even on electricity, Zcash must trade at or above 389.14 USD at standard industrial power (0.069 USD/kWh), or 676.76 USD at residential power (0.120 USD/kWh).
Bankroll & Variance Risk Simulator
Solo mining block discovery follows a memoryless Poisson distribution. While the average wait is 190 days, real-world dispersion ranges across 5% and 50% quantiles:
- Lucky streak (5% Odds): Block within ~10 days (1-in-20 fastest discovery, power cost: ~25 USD)
- Median expectation (50% Odds): Block within ~131 days (Nominal median, power cost: ~337 USD)
- Bad luck streak (5% Odds): Can stretch up to ~1.55 yr (1-in-20 extended dry spell, power cost: ~1,457 USD)
Jackpot Safe: Even in a 1-in-20 bad luck drought (~1.55 yr), the Zcash block reward (1,539 USD) covers electricity costs (~1,457 USD) with a net surplus of ~82 USD.
Innosilicon A9++ ZMaster Price & Estimated ROI
Current market price: $1,200–$1,800 (estimated market price, median $1,374) (Hardware price estimated). Mined against its most profitable coin instead of solo, it would pay itself back in about 247 days.

How the odds have moved
Zcash's network hashrate climbed 6% since 2026-09-17, from 28.77 GH/s to 30.36 GH/s — so the same rig is now 6% less likely to find a block.

How the odds are calculated
Solo mining is memoryless: every hash is an independent lottery ticket, so the wait for a block follows an exponential distribution rather than a fixed schedule. On average a block takes T = network_hashrate ÷ your_hashrate × block_time, and the probability of finding at least one within a window t is P = 1 − e^(−t/T). BackPoW uses this Poisson relation instead of a naive linear estimate. For this pair: daily chance 0.5263%, yearly chance 85.45%.
