What power does the Z15 Pro use in 2026?

Bitmain Support figures for the current Z15 Pro typically list about 2780 W wall power (+/-5%) at around 25C, or roughly 66.7 kWh per day at continuous operation, with a typical hashrate near 860 KSol/s (+/-3%).

Is the Antminer Z15 Pro Still Worth Buying in 2026?

Q: Is the Antminer Z15 Pro still worth buying in 2026?

It can be worth buying if your electricity rate sits below a realistic break-even for Equihash revenue, you already have 200-240 V infrastructure, and you specifically want ZEC/Equihash hashrate. At high residential power prices or if you expected a Bitcoin ASIC, it is usually not worth it.

We sell the current Bitmain Antminer Z15 Pro as an 860 KSol/s class Equihash machine (~2780 W wall at Bitmain’s reference ambient). That does not make every buyer a winner in 2026. This guide is the decision framework we wish more people used before checkout — including a clear “walk away” path.

What you are actually buying

Algorithm: Equihash (ZEC and related Equihash pools where supported) — not SHA-256 Bitcoin.
Typical hash: ~860 KSol/s (±3%) on current Bitmain Support-style figures (model 240-Z). Older ads still say 840K — see 860K vs 840K.
Power: ~2780 W (±5%) → about 66.7 kWh/day at 24/7.
Site needs: 200–240 V, dual AC feeds, serious noise/heat — power & wiring.

If someone promised you Bitcoin mining on a Z15 Pro, the answer is already no.

The only maths that matters

Daily power cost ≈ 66.72 × your $/kWh. Break-even rate ≈ net daily revenue ÷ 66.72. Worked examples and the live tool: electricity & break-even and the ROI calculator.

When it is more likely worth it

Yes versus no scenarios for buying Z15 Pro in 2026 — Cheap power + Equihash intent beats hype. Expensive residential power usually loses.

You have (or will install) industrial-style power at a rate that clears break-even with conservative revenue.
You specifically want ZEC / Equihash exposure or fleet diversification away from SHA-256.
You can host the noise (~75 dBA class) and heat without killing hashrate.
You buy original Bitmain stock on datasheet numbers, not a mystery “840K SEO title” used unit with no board history.

When it is usually not worth it

Typical high residential electricity with no hosting deal.
You expected a Bitcoin miner or “whatever coin is pumping.”
Apartment / shared walls with no exhaust plan.
Your entire thesis is a viral ROI graphic and zero sensitivity analysis.
You plan aggressive custom firmware as the path to profitability — see firmware and overclock vs power.

2026-specific caveats

Firmware churn: some newer builds (discussed as FR1.9 in the community) have caused pool headaches on certain cabling layouts — read before you flash.
Used market: low hashrate (700–800K) is common when heat, power, or boards are wrong — diagnose first.
Hardware still current: Z15 Pro remains Bitmain’s mainstream Equihash air box for many buyers; “worth it” is economic, not “is the model discontinued.”

A simple go / no-go checklist

Pull today’s estimated daily gross for ~860 KSol/s Equihash from a tracker you trust.
Subtract pool fees; divide by 66.72 → break-even $/kWh.
Is your real delivered power price safely under that number with margin?
Is 200–240 V + dual cords + airflow ready within budget?
Are you OK with Equihash-only for the life of the machine?

Four yeses → reasonable to buy. Two nos → wait or choose a different tool.
