Product Details

Bitmain Antminer KS3 9.4TH Top Tier KHeavyHash ASIC Miner for Kaspa (KAS)

Top bin KS3. 9.4 TH/s at 3,500W represents the best chips from Bitmain's first Kaspa manufacturing run. 29 percent more hashrate than the base KS3 7.3 TH/s model at 10 percent more power. The most KAS per watt from the KS3 generation. Universal 100 to 240V. 75 dB. Daily electricity at $0.07 per kWh: $5.88. Monthly: $176. Bitmain Antminer firmware. The KS3 9.4 TH/s approaches the IceRiver KS5L bottom bin (9 TH/s, 3,400W) on hashrate but at 3 percent more power. Nearly competitive with the newer IceRiver product. The KS3 top bin is the strongest case for buying first gen Bitmain Kaspa hardware. At 0.372 J/GH versus 0.378 J/GH on the KS5L 9 TH/s, efficiency is essentially identical. If the KS3 9.4 costs less per unit than the KS5L 9, it is genuinely the better buy at the same operating cost. For fleet operators evaluating this model: total cost of ownership equals acquisition price plus electricity ($5.88 daily at $0.07 per kWh) over your planned deployment horizon. Compare against every alternative at similar Kaspa hashrate. The model delivering more coins per dollar of total investment at your electricity rate is the correct purchase. Kaspa runs GHOSTDAG consensus at roughly one block per second. Five ASIC manufacturers create intense competition and rapid difficulty growth. Per unit profitability shifts faster than most PoW coins. Purchase the Antminer KS3 when the math works: 9.4 TH/s of Kaspa mining revenue minus $5.88 daily electricity times deployment period exceeds hardware cost. Run the numbers with current Kaspa data.
