Bitmain Antminer KS7 Kaspa Miner (40 TH/s)

The current price is in the buy box at the top of this page. It is a DDP price with duties already paid, so nothing is collected on delivery. ASIC prices move with the market, so the figure there is always today's.

40 TH/s on kHeavyHash for 3,080 W, an efficiency of 77 J/TH. The case measures 430 x 196 x 290 mm and weighs 16.4 kg. It is air cooled with the power supply built in, and it was released in May 2025.

220 to 277 V single phase. At 3,080 W that is roughly 14 amps, which a standard 20 A circuit covers. A 110 V supply is below the input range, so the machine belongs on a European or commercial feed.

Yes. It leaves stock within 1 to 3 business days of cleared payment.

No. The unit ships DDP, Delivered Duty Paid, with duties already settled, so the courier collects nothing from you.

The Bitmain manufacturer warranty, 180 days. Every unit is powered up and tested before dispatch, and if something fails we handle the claim for you.

By bank transfer (SWIFT), or with BTC, ETH, USDT and USDC.

It is the energy the machine needs to produce one terahash per second. The lower the number, the less electricity the same output costs you.

Yes. The power supply is built into the case, so there is nothing to source separately. You connect it to a suitable outlet on its own circuit.

75 dB at full fan speed from its four fans, about what a vacuum cleaner sounds like in the same room. Put it in a workshop, a warehouse or a rack room and close the door.

Yes, given the right room and the right supply. A garage, a workshop or a store room with a 220 V dedicated circuit and clear airflow will run it steadily, and with the door closed a living area stays quiet.

About 73.9 kWh a day running continuously, so roughly 2,218 kWh a month. Multiply by the rate you actually pay to get your own running cost.

Almost all of the 3,080 W leaves the case as warm air. Plan for cool air reaching the intake and a way out for the warm air, because exhaust drawn back in will make the machine throttle.

5 to 45 degrees at the intake and 10 to 90 per cent humidity. In warm weather add ventilation so the incoming air stays at the lower end of that range.

It runs kHeavyHash, so Kaspa (KAS) and the other coins on that algorithm. Payouts come from your mining pool to your own wallet.

Run the Ethernet cable to your router, switch on the power, find the miner's IP address in the router and open the Antminer web interface in a browser. Enter your pool address, worker name and wallet address, and it starts mining.

The miner runs on its own and connects through Ethernet. Once it is set up the computer can go off; you only open a browser again to check on it.

Yes. Allow a dedicated circuit for each one and check that the supply carries 220 V or more with headroom. The more units you run, the more the real problem becomes getting warm air out. Tell us the number and the site and we will plan it with you.

Keep the room as free of dust as you can and clean the four fans every few months. Dust on the intake cuts airflow, so board temperatures climb at the same room temperature and the fans work harder. Watch temperature and fan speed in the web interface.

Please ask your tax adviser. We are not able to give advice on that.
