The IceRiver KS0 ULTRA 400Gh/s Kaspa (KAS) ASIC Miner is a dedicated Kaspa (KAS) ASIC built for the kHeavyHash algorithm. If you've been waiting for a clean entry point into professional KAS mining without dropping into the hyperscale tier, this is the unit to look at.
Here's what you actually get. The kHeavyHash ASIC delivers 400 GH/s of hashrate at 0.25 J/GH efficiency, and efficiency is the number that decides whether your operation is profitable at any given power cost. Anywhere above $0.06/kWh, the efficiency gap between this unit and older hardware compounds into real revenue over a year of uptime.
IceRiver has dialed in this platform for sustained 24/7 industrial duty. The cooling system handles continuous workloads without manual intervention, the firmware is stable and well-maintained, and the plug-and-play Ethernet setup means you're hashing within minutes of unboxing. If you're operating in the Kaspa space, this is the kind of unit you build a fleet around.
Order direct from The Miner Island with free DDP shipping on orders over $5,000, we handle customs, you don't see a separate import bill. Pay with Bitcoin and save 3% on your entire order. Every unit is tested for stable hashrate before it ships.

Every order over $5,000 ships DDP-paid from our Hong Kong warehouse, so duties, taxes, and customs clearance are paid before the unit reaches you. You won't get a surprise invoice from the courier on delivery day.
Most orders dispatch within 24 to 72 hours of payment confirmation. Transit time runs 3 to 7 business days to North America, Europe, and the major mining jurisdictions. We share the tracking number the moment the airwaybill is issued.
Every unit carries a 60-day warranty from the date you receive it. Manufacturer warranties (typically 180 to 365 days depending on the brand) run in parallel and we'll help you process those claims directly with Bitmain, MicroBT, Canaan, Goldshell, IceRiver, or Elphapex.
If your unit arrives dead-on-arrival (won't power on, fails the initial hashrate test, or has visible transit damage), we replace it. Document the issue within 72 hours of delivery (a short video or photo set is enough), and we'll ship the replacement.
We accept Bitcoin, Ethereum, Litecoin, USDT, USDC, and a handful of other major cryptos through Plisio. Pay in any crypto and save 3% on your entire order. The discount applies automatically at checkout. For bulk orders over $25,000, message us on WhatsApp to discuss 50/50 staged crypto payment options.
Live estimate based on this unit's hashrate, efficiency, and coin price.
Network difficulty, coin price, and uptime all move. Treat this as a sanity-check, not a guarantee. Baseline issuance data is calibrated to May 2026; numbers drift as networks evolve. We're happy to walk through your specific power cost and target hashrate on WhatsApp.
