Top bin of Bitmain's Kaspa entry. 21 TH/s at 3,150W versus the standard KS5 at 20 TH/s and 3,000W. Five percent more hashrate at five percent more power. The efficiency per terahash is essentially identical. The PRO exists because chip grading produced higher output dies that Bitmain packaged as a premium SKU.
21 TH/s makes the KS5 PRO the highest output Kaspa ASIC from Bitmain. Combined with the Antminer ecosystem, firmware maturity, and global support infrastructure, it represents the premium choice for professional Kaspa mining operations that already operate Bitmain fleets.
Universal 100 to 240V. 75 dB. 3,150W at 220V draws about 14.3 amps. Daily electricity at $0.07 per kWh: $5.29. Monthly: $159. Marginally more than the standard KS5 ($151) for 5 percent more hashrate. The premium per unit should be modest to justify the small output gain.
For fleet buyers already running Bitmain KS5: mix standard and PRO bins based on per unit pricing. Same chassis, same firmware, same everything except chip performance. Whichever bin your distributor offers cheaper per terahash is the right buy.
For fleet operators evaluating this specific model: compare acquisition cost per terahash against every alternative at similar hashrate. Factor $5.29 daily electricity into total cost of ownership over your planned deployment. The model delivering more Kaspa per dollar of total investment (hardware plus electricity) over your deployment horizon is the correct purchase.
Top bin in Bitmain's KS5 Kaspa series. 21 TH/s at 3,150W. 1 TH/s above the standard KS5 (20 TH/s, 3,000W). Bitmain's Antminer firmware for Kaspa mining with all the ecosystem depth that brings. 75 dB at 100 to 240V.
Air cooled at 75 dB. Kaspa (KAS). Bitmain firmware. 195 x 290 x 430mm at 16.1 kg. Ethernet. 5 - 45 °C.
Industrial 75 dB requires dedicated mining space. Warehouses, containers, or isolated rooms. Not for shared environments.
Bitmain firmware for pool configuration and monitoring. Evaluate pricing against competing models at this tier.
Industrial noise at 75 dB demands purpose built mining space. Warehouses, shipping containers, dedicated rooms with sound treatment, or hosting facilities. Plan for noise management in any deployment. 3150W of heat output also requires adequate ventilation or HVAC capacity to maintain operating temperatures.
Evaluate per terahash acquisition cost and daily electricity at your rate. Total fleet hashrate determines total coins mined. Model conservatively with current network data.
Our mining specialists can help you find the perfect miner for your setup and budget.
