Description

The Bitmain Antminer Z15K is a Zcash miner that Bitmain presented in August 2026. It is built for the Equihash algorithm and can be used with it to mine Zcash. It comes in two performance levels, 525 and 565 kSol/s. A pair of fans provides the air cooling, and the machine weighs 9 kilograms.

Performance levels of the Antminer Z15K

  1. 525 kSol/s at 2,483 watts (BTM-Z15K-525KS)
  2. 565 kSol/s at 2,672 watts (BTM-Z15K-565KS)

‍

‍

In both levels that corresponds to 4.73 joules per kSol.

‍

‍

Build, connection and cooling of the Antminer Z15K

The Z15K is 133 mm wide, 245 mm deep and 290 mm high. Packed, the box is 210 x 320 x 370 mm and weighs 11 kilograms, the machine itself 9 kilograms.

‍

‍

In operation the Z15K reaches 72 decibels. That is too loud for a flat or an office; it belongs in a spot where its noise bothers nobody. Almost all of the power it draws, just under 2.5 kilowatts, leaves the machine as heat with the exhaust air. That air has to be led out of the room, otherwise the temperature there rises quickly.

‍

‍

On a 230-volt line, the 2,483 watts correspond to a current of just under 11 amperes. Anyone planning several machines calculates accordingly: three Z15K together draw a good 32 amperes and give off just under 7.5 kilowatts of heat.

‍

‍

Comparison with the previous generation of the Antminer Z15K

Ahead of the Z15K in the same range stand the Antminer Z15 from 2020 and the Antminer Z15 Pro from 2023. 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)

‍

‍

On power per kSol, the Z15K sits behind the two older models. It is not a successor in the usual sense but an extension of the range: in our view, Bitmain brought it out to make up for the tight production numbers of the Z15 Pro. It shares its outer dimensions with the Z15 but gets a quarter to a third more hashrate out of that housing. The Z15 Pro computes faster and more economically, but at 16.9 kilograms it is almost twice as heavy and considerably larger. How the three fare against miners for other coins is shown by the miner comparison on daily yield.

‍

‍

Verdict: Zcash mining with the Antminer Z15K

Zcash miners are in very high demand at the moment, and privacy coins keep gaining support. The Z15K is above all a machine for anyone who cannot get a Z15 Pro: it can be sourced at short notice.

‍

‍

Anyone starting out with the Z15K should plan for the swings. In Zcash mining, returns move up and down considerably more than in Bitcoin mining.

‍

‍

How much Zcash the Z15K earns at your tariff is shown by the Zcash mining calculator. Two figures decide the outcome, the price and the Zcash network hashrate; both sit in the cockpit updated daily, together with the Zcash pools.

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.
