Description

The Antminer KS7 is Bitmain's current air-cooled Kaspa miner, on the market since May 2025. It is built solely for kHeavyHash and therefore for Kaspa. Three performance levels cover 36 to 45 TH/s, and all three work at 77 joules per terahash. Four fans cool the unit, it weighs 16.5 kilograms and runs on 220 to 277 volts.

‍

Performance levels of the Antminer KS7

  1. KS7 36 TH/s at 2,772 watts (BTM-KS7-36TH)
  2. KS7 40 TH/s at 3,080 watts (BTM-KS7-40TH)
  3. KS7 45 TH/s at 3,465 watts (BTM-KS7-45TH)

‍

The levels differ solely in hashrate and power draw; the efficiency of 77 joules per terahash is the same for all three. The 36 and 40 TH/s levels have been available since May 2025, the 45 TH/s level was added in January 2026.

‍

Design, power connection and cooling of the KS7

The KS7 measures 430 × 195 × 290 mm. At 75 dB it is out of the question for offices or living space; it runs where the noise disturbs nobody, or in hosting. Dealers quote 5 to 45 degrees for operation and minus 40 to 70 degrees for storage, plus 10 to 90 percent humidity without condensation. Up to 3,465 watts leave the unit as heat in the exhaust air, and the room ventilation has to follow that.

‍

The power supply is built in, as on all air-cooled Antminers. The KS7 connects to 220 to 277 volts and joins the network over Ethernet.

‍

Comparison with the previous generation of the KS7

The predecessor is the Antminer KS5 Pro, which Bitmain introduced in March 2024. The two units compared:

  • Antminer KS5 Pro: 150 J/TH (20 to 21 TH/s at 3,000 to 3,150 W)
  • Antminer KS7: 77 J/TH (36 to 45 TH/s at 2,772 to 3,465 W)

‍

Depending on the level, the KS7 delivers almost twice the hashrate of the KS5 Pro and needs only about half the power per terahash to do it, while the power draw per unit stays in the same range. There is no successor yet. The daily earnings of the KS7 next to every other unit in our range are shown in the miner comparison.

‍

Verdict: Kaspa mining with the Antminer KS7

For us the KS7 is the good successor to the KS5 Pro, considerably more efficient. We do not have much experience with it yet, because only a few of them are in use with us so far.

‍

When the temperatures are right, the KS7 runs solidly; that is our current state of experience.

‍

The KS7 is today the most efficient Kaspa unit from Bitmain in our range. Run the numbers for your own electricity price in the Kaspa mining calculator. The Kaspa network hashrate and the price decide the earnings, the cockpit shows both live, along with the Kaspa mining pools with share and fees.

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.
