Overview
The Antminer KS7, launched in May 2025 by Bitmain, is tailored for Kaspa (KAS) mining using the KHeavyHash algorithm. With a hashrate of 40 TH/s and 3080 W power consumption, it delivers an efficiency of 77 J/T, making it one of the most efficient ASIC miners for Kaspa and similar coins. It operates on standard 220–277 V AC and connects via Ethernet (10/100 Mbps), fitting seamlessly into most mining setups . The operational range spans from −20 °C to 45 °C, with humidity tolerance from 10% to 90% non‑condensing
About the Coin: Kaspa (KAS)
Kaspa operates on the KHeavyHash algorithm—fully ASIC‑compatible. It continues to gain traction thanks to instant block confirmations, security, and growing community support. Mining KAS with the Antminer KS7 remains profitable even as competition increases.
Exterior Design
The KS7 features a sleek, all-metal chassis equipped with four high‑speed fans for optimal air cooling. Dimensional footprint is 430 × 195.5 × 290 mm (unit) and 570 × 316 × 430 mm packaged, weighing approximately 16.4 kg net, 18 kg gross . Under full load it produces around 75 dBA noise—typical for top-tier ASIC miners.
Packing & Size
Compact enough for rack or home setups, the KS7 uses efficient airflow design with push‑pull ventilation, aided by four powerful fans to maintain thermal stability.

Profitability Estimate (as of July 31, 2025)
Based on MiningNow’s data:
- Revenue: ~$20.30/day from ~220.94 KAS
- Profit: ~$17.34/day after electricity (assuming $0.10/kWh)
Projected Earnings:
| Period | Revenue | Electricity Cost | Net Profit |
|---|---|---|---|
| Daily | $20.30 | $2.96 | $17.34 |
| Monthly | $609 | $89.00 | $520 |
| Annually | $7,420 | $1,080 | $6,340 |
Variables such as pool fees, downtime, and changing KAS value will of course affect real outcomes.
