The IceRiver KS0 ULTRA is a compact and ultra-efficient ASIC miner designed for the KHeavyHash algorithm, purpose-built for Kaspa (KAS) mining. Delivering 400 GH/s of hashrate while consuming just 100W, the KS0 ULTRA is ideal for home miners, beginners, and low-noise environments.
Released in May 2024, the KS0 ULTRA features a fanless, silent design with a noise level of only 35 dB, making it suitable for desktops, apartments, or office setups. Its extremely low power draw allows users to mine Kaspa with minimal electricity costs and without specialized electrical infrastructure.
While not intended for industrial-scale mining, the KS0 ULTRA is perfect for users seeking entry-level Kaspa exposure, network participation, or an energy-efficient always-on miner backed by IceRiver’s proven Kaspa hardware lineup.
