GeForce RTX 3090 on Nexa — Mining Profit, Solo Odds & Cost of Production

129.70 MH/s · NexaPow · network 2.67 TH/s. A GeForce RTX 3090 solo mining Nexa (NEXA) has about 13 blocks per year, i.e. an expected block roughly every 28 days for the full 5,000,000.0000 NEXA (≈ 5 USD) reward.

GeForce RTX 3090 on Nexa — Mining Truth Benchmark & Specifications

Consolidated PoW oracle metrics for operating a GeForce RTX 3090 on Nexa (NEXA) at live network difficulty and benchmark industrial electricity (0.069 USD/kWh):

Can you solo mine Nexa with a GeForce RTX 3090?

Yes — a GeForce RTX 3090 (129.70 MH/s) can solo mine Nexa (NEXA) via a solo pool. At Nexa's 2.67 TH/s NexaPow network that is about 13 blocks per year — expected one block roughly every 28 days, for the full 5,000,000.0000 NEXA (≈ 5 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 Nexa

The GeForce RTX 3090 is categorized in the Mid-Range Workhorse Tier (Middle quartile hashrate offering solid pool mining throughput with moderate solo variance.). Among all 8 tracked models on Nexa, it ranks #5 in electrical efficiency (498,850.00 H/W) and #5 in raw hashrate (129.70 MH/s).

Electricity Operating Costs & Breakeven

Running a GeForce RTX 3090 (260 W) pulls about 6.24 kWh per day (189.9 kWh per month). At the standard rate of 0.069 USD/kWh, electricity costs roughly 0.43 USD per day (13.11 USD/month or 157 USD/year). Statistically that year returns 12.84 blocks, worth about $62.14 — you would burn roughly 3x more in electricity than that reward is worth.

The operational breakeven threshold is 0.027 USD/kWh. Expected net operating margin at benchmark tariffs:

• At 0.040 USD/kWh (Hydro / Renewable): -0.08 USD / day
• At 0.069 USD/kWh (Standard Industrial): -0.26 USD / day
• At 0.120 USD/kWh (Residential Grid): -0.58 USD / day

Break-even Coin Price Target: For this hardware to break even on electricity, Nexa must trade at or above 0.00000245 USD at standard industrial power (0.069 USD/kWh), or 0.00000426 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 28 days, real-world dispersion ranges across 5% and 50% quantiles:

• Lucky streak (5% Odds): Block within ~1 days (1-in-20 fastest discovery, power cost: ~1 USD)
• Median expectation (50% Odds): Block within ~20 days (Nominal median, power cost: ~8 USD)
• Bad luck streak (5% Odds): Can stretch up to ~85 days (1-in-20 extended dry spell, power cost: ~37 USD)

High Variance Alert: In a 1-in-20 severe drought (~85 days), cumulative electricity burned (~37 USD) will exceed the block reward value (5 USD). Pool mining is recommended for risk-averse operators.

GeForce RTX 3090 Price & Estimated ROI

Current market price: $580–$720 (estimated market price, median $650) (Hardware price estimated). Mined against its most profitable coin instead of solo, it would pay itself back in about 300 days.

How other hardware compares on Nexa

How the odds have moved

Nexa's network hashrate climbed 29% since 2026-09-08, from 2.07 TH/s to 2.67 TH/s — so the same rig is now 29% less likely to find a block.

Where to point a GeForce RTX 3090 at Nexa

Solo mining still runs through a solo pool: it handles the block template and pays the full reward to whoever finds the block. BackPoW tracks 7 solo pools for Nexa with their stratum endpoints, fees, and pool hashrates — see Nexa solo mining pools:

• woolypooly.com (Fee: 0.9% · Hashrate: 53.39 GH/s)
• pool.kryptex.com (Fee: 1% · Hashrate: 33.70 GH/s)
• 2miners.com (Fee: 1.5% · Hashrate: 2.55 GH/s)

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 3.45%, yearly chance 100.00%.

Frequently Asked Questions: GeForce RTX 3090 on Nexa

Can you solo mine Nexa with a GeForce RTX 3090?

Yes — a GeForce RTX 3090 (129.70 MH/s) can solo mine Nexa (NEXA) via a solo pool. At Nexa's 2.67 TH/s NexaPow network that is about 13 blocks per year — expected one block roughly every 28 days, for the full 5,000,000.0000 NEXA (≈ 5 USD) block. BackPoW computes this from live network difficulty using a Poisson block-discovery model.

Is NexaPow ASIC-resistant, and where does the GeForce RTX 3090 stand?

NexaPow is an ASIC-resistant GPU algorithm relying on memory bandwidth. The GeForce RTX 3090 ranks #5 of 8 GPUs on Nexa. It operates in the Mid-Range Tier (middle quartile), offering solid pool mining throughput with moderate solo variance.

What is the operating power cost and breakeven electricity rate for a GeForce RTX 3090 on Nexa?

At 260 W, operating a GeForce RTX 3090 consumes 6.24 kWh/day (189.9 kWh/month). At standard electricity (0.069 USD/kWh), the power bill is 0.43 USD/day (13.11 USD/month). The operational breakeven threshold is 0.027 USD/kWh.

What happens if my GeForce RTX 3090 encounters a severe dry spell on Nexa?

Block discovery is an independent Poisson process with no memory. In a 1-in-20 bad luck drought (5% worst luck), finding a block can stretch up to 85 days, accumulating roughly 37 USD in power costs.
