About this miner
Purpose-built Equihash ASIC for Zcash and Horizen. The same class of hardware stocked by specialist ASIC retailers.
Why buy the Antminer Z15 Pro 860K
The Bitmain Antminer Z15 Pro 860K is an air-cooled Equihash ASIC for Zcash (ZEC) and Horizen (ZEN). At a typical 860 KSol/s and 2780 W on the wall (@ 25°C), it suits operators who want dedicated Zcash hash power instead of GPU fleets.
Privacy-focused networks historically run with different difficulty dynamics than SHA-256. That can matter if you are diversifying beyond Bitcoin ASICs, but profitability still depends on coin price, pool fees and your electricity rate. Use the calculator below before you buy.
We publish Bitmain’s official support values for this model (hashrate ±3%, power and efficiency ±5%). Some third-party listings still show older figures (for example “840K” labels or 2560–2650 W). We stay with current Bitmain Support data for the 860 KSol/s unit (model 240-Z).

Frequently asked questions
Quick answers. Full FAQ covering mining basics, power, payment, shipping and warranty.
Is Antminer Z15 Pro 840K the same as Z15 Pro 860K?
Older listings sometimes say “840K”. The unit we sell is the current Antminer Z15 Pro 860K with Bitmain’s typical 860 KSol/s rating (model 240-Z).
Which coins can the Z15 Pro mine?
Equihash: Zcash (ZEC) and Horizen (ZEN). It is not a Bitcoin (SHA-256) miner.
How much power does it use?
Official typical wall power is 2780 W at 25°C (±5%), about 66.7 kWh/day at 24/7. Needs 200–240 V AC and properly rated circuits/cords.
How do I pay?
BTC, USDC or USDT only. Full payment in advance. Wallet address is shown after you place the order.
Can I cancel after ordering?
ASIC orders are generally final once placed, because hardware markets move quickly. Read the Terms before paying.
What about shipping and customs?
Fixed shipping is $150. Duties/VAT in your country (if any) are the buyer’s responsibility. Track via Track order.
What warranty do I get?
Bitmain manufacturer warranty typically 180 days from delivery. See Warranty & repairs.
