The Antminer Z15 Pro in Detail

The Bitmain Antminer Z15 Pro is Bitmain's most powerful Equihash miner and has been on the market since June 2023. It is the direct successor to the Antminer Z15 and was developed specifically for mining Zcash (ZEC) - the leading cryptocurrency based on the Equihash algorithm.

‍

With a hashrate of 820 to 860 KSol/s at a power consumption of approx. 2,715 to 2,845 W, the Z15 Pro achieves an efficiency of around 3.3 J/KSol. Two high-performance fans and Bitmain's proven air cooling are designed for continuous 24/7 operation; the RJ45 Ethernet interface makes the miner easy to integrate into existing setups. You will find all technical details in the specifications.

‍

Mixed Batch and Pricing

Bitmain produces the Z15 Pro in four performance bins (820, 840, 850 and 860 KSol/s) and ships them from the factory in mixed batches - as a dealer, we cannot order a specific bin either. The exact bin of an individual unit is only known upon delivery. In any case, you will receive a brand-new Z15 Pro within this range.

‍

As with all mining hardware, the price is determined by the hashrate. The listed price refers to the base bin with 840 KSol/s; if Bitmain delivers a different bin, the price is adjusted accordingly:

  • 840 KSol/s: base price
  • 850 KSol/s: +100 EUR
  • 860 KSol/s: +200 EUR
  • 820 KSol/s: -200 EUR

‍

Availability and Batches

The Z15 Pro is in stock and ships immediately. In addition, you can pre-order upcoming production batches at staggered prices - currently July, October and November: earlier batches reach you faster, later ones are more affordable.

‍

Comparison with the Predecessor: Z15 vs. Z15 Pro

The leap from the Antminer Z15 (2020) to the Z15 Pro is one of the biggest within a Bitmain product line: the hashrate doubles from 420 to around 840 KSol/s, while the energy required per unit of computing power drops from about 3.6 to around 3.3 J/KSol. A single Z15 Pro thus replaces two units of the previous generation - with less rack space, less cabling and lower total consumption for the same output. For operators of older Z15 units, upgrading is above all an infrastructure decision: the same performance with half as many machines.

‍

Zcash Mining with the Antminer Z15 Pro

Zcash is one of the oldest privacy cryptocurrencies: on the market since 2016 and built on zk-SNARKs - a technique that keeps transactions encrypted yet verifiable. Zcash is mined via proof of work using the Equihash algorithm, with a block time of 75 seconds. Like Bitcoin, Zcash has a halving roughly every four years; most recently, the block reward was halved to 1.5625 ZEC per block in November 2024.

‍

Equihash was originally designed for graphics cards; since specialized ASICs became available, machines like the Z15 Pro have delivered many times the performance of a GPU at lower consumption - GPU mining therefore plays virtually no role in Zcash today. Horizen (ZEN), formerly the second major Equihash coin, switched to proof of stake in July 2025 and can no longer be mined; Equihash mining is now focused on Zcash. You will find all available units in our Zcash miner overview.

How the Purchase Process works

1
Make a Request
You send us an inquiry for the mining hardware you want. We check availability, prices and delivery time and, upon request, also create offers with volume discounts.
2
Get an Offer
You will receive a specific offer with all technical data, prices and the respective terms of delivery and payment. This gives you a transparent overview of hardware, costs and delivery time.

Warranty provided by our German Company

When you buy mining hardware via Cryptohall24, you get a guarantee of 12 months In contrast to manufacturer warranties, our warranty only begins when the hardware is sold to our customers and not as soon as it leaves the factory. Since there can often be several months between production and sale in the mining market, our customers often have a longer effective protection than with the pure manufacturer's warranty.
‍
Optionally, the hardware can be added to insured for up to 36 months become.

FAQ
Do you have any questions?

How does buying a miner work?

The process is clear and done in a few steps: you enquire about the device you want, you receive a written quote with the final price from us, and as soon as you accept it, we issue the invoice. After full payment is received, we trigger the order and the hardware is on its way to you.

That way you know where you stand at every point - from quote to delivery, a continuously supported process with a personal contact.

How can I pay?

You can pay conveniently by bank transfer in euros, in crypto (Bitcoin or USDC) or in cash against a receipt.

As throughout our business, payment is in advance: we trigger the order as soon as payment has been received in full. That keeps the process clean and predictable for both sides.

Are there discounts for larger quantities?

Yes, discounts are possible for larger quantities. How large they are depends on several factors - the device, the quantity, the delivery location and the respective procurement conditions.

That's why we state the right price best directly in an individual quote. Just tell us the model and the quantity you want and we'll work it out for you.

What is included in the delivery?

On modern ASIC miners the power supply is built firmly into the machine and is therefore always included - it does not have to be bought separately. An external power supply only existed with very old first-generation models.

So you receive a ready-to-run device. Whatever else specifically belongs to the respective product is stated in the product description; in case of doubt we clarify it in the quote.

Is the miner in stock and how quickly is it delivered?

You can see availability directly on the product; in case of doubt we confirm it in the quote. The majority of our hardware is located in our main warehouse in Hong Kong and is shipped from there directly to your destination.

Individual devices are in stock in Germany (Hamm) - those reach you particularly quickly. We state the concrete delivery date bindingly in the quote, as soon as device and destination are clear.

How is it delivered - internationally and with customs clearance too?

We deliver worldwide. We handle the shipping and the complete import processing including customs clearance for you - you don't have to deal with it yourself. We state the shipping costs transparently in the quote.

That way the miner arrives ready to use at your place or the desired site. On request we deliver directly to our hosting, then the device goes into operation without a detour.

What requirements do I need for operation?

To operate at home or in your own business you mainly need three things: a suitable power connection (ASIC miners draw several kilowatts continuously, large devices often three-phase power), enough space with ventilation, and a stable internet connection via LAN.

On top of that come noise and waste heat: air-cooled devices are very loud and heat the room noticeably. Anyone who doesn't meet these requirements usually has the miner hosted - then we take care of power, cooling and operation.

How do I set up the miner and can I get help?

Commissioning is straightforward: connect the device, plug it into the network and configure it to your mining pool and wallet. After that the miner runs around the clock.

We don't leave you alone with it - we support you with setting up pool and wallet and the first steps, even without prior experience. Your personal contact is available for questions.

What warranty do I have on the device?

As a German company we offer you 12 months' warranty on your hardware as standard.

Alternatively, you can exclude the warranty in the purchase contract and handle it via the manufacturer's warranty - then the device becomes cheaper. We offer both routes; which one makes sense for you we clarify in the quote.

Can I have this miner hosted directly instead of running it myself?

Yes. You can buy the device from us and have it hosted in the same step - then it runs at a site with low-cost electricity, without noise and heat at your home.

For many this is the most economical way. You can read how hosting works on our hosting page.

As a business customer, can I cancel or return?

We sell our devices to businesses (B2B). A statutory consumer right of withdrawal therefore does not apply in B2B business; in addition, we procure and import the hardware specifically for your order.

So you buy in a targeted and binding way. That's exactly why we calmly clarify the right device for your project before the quote - so you make the right choice from the start. If you have questions before buying, we are always reachable.
