Bitmain Antminer KS7 (45TH)

The Antminer KS7 is the strongest Kaspa mining hardware available from any manufacturer. At 45 TH/s on the KHeavyHash algorithm and 3,080W wall draw, the top bin KS7 produces 68.44 J/TH efficiency from Bitmain's latest KHeavyHash chip architecture. For context: the previous generation KS5 Pro delivered 21 TH/s at 3,150W and 150 J/TH. The KS7 more than doubles the hashrate at roughly the same power draw while cutting per terahash energy cost by 46 percent.

Bitmain ships the KS7 in three performance tiers based on chip binning. The base bin runs at 36 TH/s and 2,772W. The mid bin runs at 40 TH/s and 3,080W. The top bin (carried by MillionMiner) runs at 45 TH/s and 3,080W, achieving the best efficiency of the three. All tiers share the same physical chassis at 430 x 196 x 290 mm and the same 220 to 277V input requirement.

Kaspa's network grew from a niche proof of work experiment to a top 30 cryptocurrency by market capitalization in roughly two years. The KHeavyHash algorithm was specifically designed to be ASIC friendly while remaining memory hard enough to prevent complete GPU obsolescence. Dedicated ASICs like the KS7 now dominate Kaspa's hashrate. The network processes one block per second using a blockDAG architecture, which means difficulty adjusts faster than Bitcoin and new hashrate gets priced in more quickly. Early KS7 deployers capture the highest returns before the install base expands.

The KS7 also mines Sedra (SDR) and any other cryptocurrency built on the KHeavyHash algorithm. Pool options for Kaspa include F2Pool, ViaBTC, WoolyPooly, KaspaPool, and ACC Pool among others. Configure pool and wallet through the standard Bitmain web interface over Ethernet.

75 dB air cooled operation from four fans. Standard industrial ASIC noise requiring dedicated mining space. Not suitable for bedrooms or shared living areas. 220 to 277V AC input; the KS7 does not support 110V residential power. At 220V the unit draws approximately 14 amps, comfortable on a standard 20 amp commercial circuit. PSU ships included with C20-P13 Antwire cable. Source a C19 power cord locally if not included in your batch.

Daily electricity at $0.07 per kWh runs approximately $5.17. At $0.04 per kWh industrial rates: $2.96 daily. Current KAS mining revenue at 45 TH/s fluctuates with Kaspa price and network difficulty but has historically provided strong margins relative to hardware cost compared to Bitcoin mining at equivalent investment levels.

Kaspa's relatively young ASIC mining ecosystem means hardware competition is thinner than Bitcoin, which is the core opportunity.
