Product Details

IceRiver KS7 30TH KHeavyHash Kaspa ASIC Miner for Professional KAS Mining Operations

IceRiver shipped the first dedicated KHeavyHash ASICs for Kaspa mining, establishing the brand in the KAS community before Bitmain released competing hardware. The KS7 at 30 TH/s and 3,500W represents the peak of their industrial KS lineup. The elephant in the room is the Bitmain Antminer KS7 at 40 TH/s and 3,080W. Bitmain produces 33 percent more hashrate at 12 percent less power. On pure specs, the IceRiver KS7 loses. Where IceRiver competes: pricing (often significantly cheaper per unit than Bitmain), firmware maturity (shipping Kaspa miners longer means more tested software), and availability (IceRiver stock is frequently easier to source than Bitmain KS series). Kaspa runs GHOSTDAG consensus, processing multiple blocks in parallel through a directed acyclic graph structure. Faster confirmations than traditional single chain blockchains. KHeavyHash proof of work secures the network. Kaspa has grown into one of the largest proof of work communities outside Bitcoin, with active development and strong exchange presence. 200 to 250V input is narrower than some competitors. Not compatible with 110V. Verify your facility voltage specifically. 75 dB requires dedicated mining space. 17.5 kg at 430 x 195 x 290mm. IceRiver's full KS range covers every deployment scale: KS0 (100 GH/s, 65W desktop), KS0 Pro (200 GH/s), KS0 Ultra (400 GH/s), KS2 Lite (2 TH/s, 500W home), KS7 Lite (4.2 TH/s, 500W home), and KS7 (30 TH/s industrial). One ecosystem from hobby to production. Ethernet connectivity. 5 to 40 degrees Celsius.

IceRiver KS7 30TH KHeavyHash Kaspa Professional ASIC Miner

IceRiver's industrial Kaspa flagship. 30 TH/s KHeavyHash at 3,500W. First manufacturer to ship dedicated Kaspa ASICs. Longer firmware maturity than Bitmain KS hardware. Bitmain KS7 (40 TH/s, 3,080W) is faster and more efficient on specs. IceRiver competes on pricing, availability, and established Kaspa firmware. Often significantly cheaper per unit and easier to source. Full IceRiver KS ecosystem from 65W home to 3,500W industrial. One brand, one firmware platform across all scales. 200 to 250V at 75 dB. 17.5 kg at 430 x 195 x 290mm. Ethernet. 5 to 40 degrees Celsius. Kaspa GHOSTDAG consensus. Kaspa has grown from a niche project into one of the top 30 cryptocurrencies by market cap. The transition from GPU to ASIC mining dramatically increased network hashrate but also increased efficiency requirements for profitable mining. IceRiver's early position means more established pool relationships, better tested firmware for edge cases, and a broader community of users sharing operational knowledge.

Frequently Asked Questions

30 TH/s of kHeavyHash at 3,500W. The most powerful dedicated Kaspa miner from IceRiver — 50% more hashrate than the Bitmain KS5 (20 TH/s).

KS7: 30 TH/s at 3,500W (IceRiver). KS5: 20 TH/s at 3,000W (Bitmain). The KS7 delivers 50% more hashrate but at higher power. Better raw output, slightly less efficient.

At 30 TH/s, the KS7 commands a large share of Kaspa network hashrate. Current KAS prices make profitability electricity-dependent. At hosting rates ($0.055/kWh), economics improve significantly.
