IceRiver KS0 Ultra (400Gh)

The IceRiver KS0 Ultra is a purpose-built ASIC for the KHeavyHash algorithm, delivering a concentrated 400 GH/s hashrate while drawing just 100 W - an efficiency of 4 GH/s per watt that reframes mining as a matter of disciplined engineering rather than brute force; designed for home or small-farm deployment, its compact 200 x 194 x 74 mm footprint and 2.5 kg weight permit flexible placement, and a whisper-quiet 10 dB operation keeps it unobtrusive in both living and office environments. Internally it pairs enhanced thermal regulation and a refined power-management architecture with durable components and an advanced cooling system to sustain stable performance over extended runs, while Ethernet connectivity and broad mining-pool compatibility make setup straightforward for novices and scalable for seasoned operators. Optimized for Kaspa (KAS) and Sedra (SDR), the KS0 Ultra turns the KHeavyHash algorithm’s demands into a low-impact, high-throughput proposition, minimizing environmental footprint through modest power consumption and low noise, and its combination of efficiency, reliability and ease of use makes it well suited for single-unit hobbyists and clustered farms alike; for realistic expectations of return, pair its measured specs with a crypto miner profit calculator to model daily, monthly and annual outcomes across different electricity rates and network conditions.

The IceRiver KS0 Ultra is a purpose-built ASIC for the KHeavyHash algorithm. It delivers 400 GH/s while consuming just 100 W, roughly 4 GH/s per watt. The unit measures 200 x 194 x 74 mm and weighs 2.5 kg, so placement is flexible. Noise sits at a mere 10 dB and keeps it unobtrusive in homes and offices. Cooling comes from a custom heatsink and optimized airflow that hold temperatures steady under continuous load. A refined power regulation stage minimizes voltage fluctuation and protects long-term stability. Firmware allows fine-grained hashrate tuning to adapt to ambient conditions and network demands. An improved PCB layout boosts signal integrity, cutting errors and raising computational reliability. Robust components and the enhanced cooling system sustain reliable performance during extended runs. The compact, stackable design makes it ideal for single-unit hobbyists and tightly packed small farms. Setup is plug-and-play via Ethernet with broad mining-pool compatibility. That simplicity helps beginners start fast and lets experienced operators scale. Optimized for Kaspa (KAS) and Sedra (SDR), the KS0 Ultra turns the KHeavyHash workload into a quiet, energy-efficient mining solution. Its low power draw and minimal noise lower operating impact while preserving strong throughput.

KHeavyHash je kryptografická hashovací funkce, která slouží jako základna pro Kaspa důkaz-práce konsenzuální mechanismus. Tento algoritmus zpracovává vstupní data libovolné délky a produkuje pevnou hash hodnotu, čímž zajišťuje bezpečnost a integritu v procesu těžby.
