Can you solo mine Kaspa with a Radeon RX 7900 XTX?
Yes — a Radeon RX 7900 XTX (1.20 GH/s) can solo mine Kaspa (KAS) via a solo pool. At Kaspa's 329.80 PH/s kHeavyHash network that is about a 1-in-1 chance per year — expected one block roughly every 319 days, for the full 2.1827 KAS 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 Kaspa
The Radeon RX 7900 XTX is categorized in the Mid-Range Workhorse Tier (Middle quartile hashrate offering solid pool mining throughput with moderate solo variance.). Among all 20 tracked models on Kaspa, it ranks #19 in electrical efficiency (4,435,555.56 H/W) and #9 in raw hashrate (1.20 GH/s).
Electricity Operating Costs & Breakeven
Running a Radeon RX 7900 XTX (270 W) pulls about 6.48 kWh per day (197.2 kWh per month). At the standard rate of 0.069 USD/kWh, electricity costs roughly 0.45 USD per day (13.61 USD/month or 163 USD/year). Statistically that year returns 1.15 blocks, worth about $0.105 — you would burn roughly 1,555x more in electricity than that reward is worth.
The operational breakeven threshold is 0.000 USD/kWh. Expected net operating margin at benchmark tariffs:
- At 0.040 USD/kWh (Hydro / Renewable): -0.26 USD / day
- At 0.069 USD/kWh (Standard Industrial): -0.45 USD / day
- At 0.120 USD/kWh (Residential Grid): -0.78 USD / day
Break-even Coin Price Target: For this hardware to break even on electricity, Kaspa must trade at or above 65.29 USD at standard industrial power (0.069 USD/kWh), or 113.55 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 319 days, real-world dispersion ranges across 5% and 50% quantiles:
- Lucky streak (5% Odds): Block within ~16 days (1-in-20 fastest discovery, power cost: ~7 USD)
- Median expectation (50% Odds): Block within ~221 days (Nominal median, power cost: ~99 USD)
- Bad luck streak (5% Odds): Can stretch up to ~2.61 yr (1-in-20 extended dry spell, power cost: ~427 USD)
High Variance Alert: In a 1-in-20 severe drought (~2.61 yr), cumulative electricity burned (~427 USD) will exceed the block reward value (0 USD). Pool mining is recommended for risk-averse operators.
Radeon RX 7900 XTX Price & Estimated ROI
Current market price: $750–$900 (estimated market price, median $815) (Hardware price estimated). Mined against its most profitable coin instead of solo, it would pay itself back in about 599 days.

How the odds are calculated
Each hash is an independent attempt, so block discovery is memoryless and follows an exponential distribution. The average time to a block is T = network_hashrate ÷ your_hashrate × block_time. The chance of hitting at least one block within a period t is then given by the Poisson relation P = 1 − e^(−t/T) — the realistic probability, not a misleading linear one. For this pair: daily chance 0.3132%, yearly chance 68.21%.
