Description

Bitmain has offered the Antminer Z15 Pro, a Zcash miner, since 2023. Equihash is the algorithm it was designed for, and Zcash the coin it mines. It ships in four performance levels from 820 to 860 kSol/s, with the typical level at 840 kSol/s. Two fans cool it with air, it weighs 16.9 kilograms and is connected through two power inputs.

‍

Performance levels of the Antminer Z15 Pro

  1. 820 kSol/s at 2,560 watts (BTM-Z15PRO-820KS)
  2. 840 kSol/s at 2,780 watts (BTM-Z15PRO-840KS)
  3. 850 kSol/s at 2,780 watts (BTM-Z15PRO-850KS)
  4. 860 kSol/s at 2,920 watts (BTM-Z15PRO-860KS)

‍

The levels differ in hashrate and power draw. The typical 840 kSol/s level works out to 3.31 joules per kSol, and across all four levels the efficiency lies between 3.12 and 3.40 joules per kSol. The actual hashrate of a machine deviates by up to three percent from the rated value, the power draw by up to five percent.

‍

Build, connection and cooling of the Antminer Z15 Pro

The housing measures 428 x 195 x 290 mm and holds 18 chips on three hash boards. In its 597 x 317 x 427 mm box, the Z15 Pro weighs 18.8 kilograms.

‍

At full fan speed it reaches 75 decibels, which places it somewhere the noise bothers nobody. It may be operated at 0 to 40 degrees ambient temperature and 10 to 90 percent humidity, as long as no condensation forms; storage is allowed between minus 20 and 70 degrees. Above 900 metres of altitude, the maximum permitted temperature drops by one degree per 300 metres, with the limit at 2,000 metres. Its almost 2.8 kilowatts of power draw come back out nearly in full as warm exhaust air, and that belongs outside.

‍

It connects to 200 to 240 volts AC at 50 or 60 hertz, through two power inputs at 10 amps each, so 20 amps together. The power supply has to deliver at least 4,000 watts of output, and a wrong input voltage can damage the machine. The Z15 Pro joins the network via RJ45 at 10/100 Mbit/s.

‍

Comparison with the previous generation of the Antminer Z15 Pro

The Z15 Pro followed the Antminer Z15 from 2020. In 2026 Bitmain extended the range with the compact Antminer Z15K. The three machines compared:

  • Antminer Z15: 3.6 J/kSol (420 kSol/s at 1,510 watts)
  • Antminer Z15 Pro: 3.31 J/kSol (840 kSol/s at 2,780 watts)
  • Antminer Z15K: 4.73 J/kSol (525-565 kSol/s at 2,483-2,672 watts)

‍

Compared with the Z15, the Z15 Pro doubles the hashrate and needs less electricity per kSol, which makes it the strongest and the most economical miner of the range. We see the Z15K as an addition with which Bitmain compensates for the small production numbers of the Z15 Pro: it is smaller and lighter, but needs considerably more electricity per kSol. For a side-by-side view of daily yield with miners for other coins, use the miner comparison.

‍

Verdict: Zcash mining with the Antminer Z15 Pro

Not many Z15 Pro were built, and demand is currently very high. The reason lies in the numbers: the machines have recently worked exceptionally profitably, and privacy coins keep gaining in popularity. Anyone entering here must, however, expect considerably more fluctuation than in Bitcoin mining, say; returns move more strongly in both directions.

‍

In operation the machines run well for us, and failures straight out of the box are rare. One point belongs here in all honesty: the hashrate of the Z15 Pro is not as steady as that of a Bitcoin miner. It moves noticeably up and down during operation, and that has been the case with this model from the start. Anyone monitoring output should therefore look at the average over a longer period, not the momentary value.

‍

A look at the return: the Zcash mining calculator uses your electricity price to work out what the Z15 Pro brings in per day. What decides it are the Zcash price and the Zcash network hashrate, both updated daily in the cockpit, as is the overview of Zcash pools.

‍
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.
