Everything you need to know about comparing and running Zcash mining hardware in 2025.
The Antminer Z15 Pro leads at 302 Sol/W - the highest efficiency of any Zcash ASIC currently available. It delivers 840 KSol/s at 2,780W. No other hardware comes close on the efficiency metric that actually determines profitability.
Use Sol/W (solutions per watt) as the primary metric, not raw hashrate. Higher Sol/W means more ZEC mined per dollar of electricity. A miner with twice the hashrate but three times the power is a worse investment at realistic electricity costs. Then factor in hardware cost to get a full ROI picture.
Profitability depends entirely on your electricity cost. With a Z15 Pro at sub-$0.08/kWh, ZEC mining can generate positive returns. At $0.13/kWh (US residential average), it's marginal. Use our calculator with your real electricity rate and the live ZEC price for an accurate estimate.
The current ZEC block reward is 3.125 ZEC per block after the November 2024 halving. Blocks are found approximately every 75 seconds (roughly 1,152 blocks per day). At 9 GH/s network hashrate, a single Z15 Pro mines approximately 0.054 ZEC per day.
F2Pool is recommended for most miners globally - PPS+ payouts, 1% fee, proven uptime. Luxor is best for North American miners with its 0.5% fee (lowest available). Both support the Z15 Pro with full stratum protocol.
GPU mining for Zcash is not economically viable. ASIC miners like the Z15 Pro are 100× more efficient on the Equihash algorithm. A modern GPU might achieve 700–1,000 Sol/s - the Z15 Pro does 840,000. GPU ZEC mining results in a heavy loss at any residential electricity rate.
Zashi (official Zcash Foundation wallet) supports shielded transactions and is the recommended choice for privacy-conscious miners. Ywallet is another strong option with advanced shielding features. For convenience, Coinbase and Kraken both support ZEC deposits directly from pools.
The most recent halving occurred in November 2024, reducing the block reward from 6.25 to 3.125 ZEC. The next halving is expected around 2028. Plan your hardware ROI accordingly - the next halving will cut revenue per machine in half at unchanged ZEC price and difficulty.
The Z15 Pro operates at approximately 75 dB(A) under load - comparable to a loud vacuum cleaner running continuously. It is not suitable for home or shared office environments without soundproofing. Most serious operators use dedicated mining rooms, industrial units, or co-location facilities.
The Z15 Pro requires 240V power and draws approximately 2,780W. You need a dedicated 20A 240V circuit per miner (a 15A circuit is insufficient for sustained 2,780W draw). In North America, this typically means a 30A 240V circuit to run one miner safely with headroom. Plan your electrical infrastructure before ordering hardware.
