Bitmain Antminer Z15K 525 kSol/s Zcash Equihash Miner

525 kSol/s of Equihash hashrate at a published draw of 2,483W, which works out to 4.73 J/kSol. Those figures come from seller listings rather than a Bitmain specification page, so confirm them against the documentation supplied with your batch before you plan a deployment around them. Anyone sizing a circuit or a facility should treat the power figure as provisional until it is verified on delivered units.

Coins on the Equihash algorithm, with Zcash (ZEC) as the primary target for its larger network and deeper liquidity. Horizen (ZEN), Komodo (KMD), Hush and Pirate Chain (ARRR) are the practical alternatives. Equihash does not support merged mining, so the machine runs one coin at a time and operators use a profitability switching tool to point it at whichever pays best. It cannot mine Bitcoin or any SHA-256 coin, Litecoin on Scrypt, or Kaspa, so it is a dedicated Equihash machine rather than a flexible one.

200 to 240V AC single phase with a maximum current of 20 amps per the published specification, so a dedicated 240V circuit rather than a standard household socket. At 2,483W it draws roughly 10 to 11 amps continuously at 240V, which fits a 20 amp circuit with sensible headroom. European Schuko, UK BS 1363, Middle Eastern 220 to 240V and North American 240V NEMA 6 outlets all work, and no three phase service is required. For a multi unit order, size the panel on measured draw from the first delivered units rather than the published figure alone.

Published figures put it around 72 to 75 dB from a dual fan air cooled design, industrial noise comparable to a vacuum cleaner at close range, and 2,483W of draw becomes roughly 8,500 BTU per hour of heat. That rules out living spaces. A dedicated mining room, a ventilated garage or outbuilding, or a hosting facility are the appropriate homes, with a clear intake at the front and an unobstructed exhaust path behind. Because the published chassis is compact for this power level, pay particular attention to airflow and inlet temperature in multi unit rows.

Returns depend on the ZEC price, Zcash network difficulty and your electricity rate, and no fixed daily figure stays accurate. Because efficiency is the fixed part of that equation, the Z15K's published 4.73 J/kSol means power cost weighs more heavily here than on the Z15 or Z15 Pro, so it needs genuinely cheap electricity to compete. Run your own rate through the live calculator before ordering, and if you are comparing it against other Equihash hardware, compare on cost per kSol delivered and energy per kSol rather than on headline hashrate.

Setup follows the standard Antminer workflow. Confirm a dedicated 220 to 240V circuit with proper grounding, make sure the space can carry the thermal load, connect the power supply and an RJ45 Ethernet cable to your router or switch, then power on and find the miner's IP through your router's DHCP list or an IP scanner. Open the web interface, change the default credentials immediately, enter a Zcash wallet address and your pool URL, and confirm hashrate settles near the rated figure within about ten minutes. Any major Equihash pool works, including Flypool, Luxor, 2miners, ViaBTC and Nanopool, with fees typically 0.5 to 2 percent.

It is standard air cooled ASIC upkeep: clear dust from the fans and heatsinks regularly, inspect the hashboard connectors periodically, keep inlet air inside the rated range, and treat fans as a wear item over a long deployment. On delivery, and particularly on a batch, check more than the box: confirm the hashrate each unit actually reports under sustained load rather than at startup, confirm all hashboards are detected with full chip counts, and measure real wall draw on the first few units against the published figure before you size the rest of the installation. On newly listed hardware those measurements are worth doing properly, because they are what tell you whether the published specification holds.

Seller listings report an included PSU and a six month factory warranty, but both should be confirmed on your specific batch at order rather than assumed, because bundling and warranty terms vary by channel and batch on newly listed hardware. Ask for the warranty term in writing, confirm what the box contains, and check whether the supply provided delivers the connectors the hashboards require. MillionMiner ships worldwide DDP with customs clearance, duties and taxes handled, so the quoted figure is the final landed cost.

Yes. MillionMiner operates managed US facilities with 220 to 240V single phase service and the ventilation air cooled hardware needs, and hosting is worth considering here because at 4.73 J/kSol the electricity rate carries more weight than it does on more efficient Equihash hardware. For batch orders, availability, current pricing and minimum quantities, contact sales through the Get a Quote button rather than relying on any figure published on this page, since batch terms move with supply. Ask about the free 24 hour trial and about hosting rates at the same time so you can compare self hosting against a managed rate before committing.
