Product Details

IceRiver KS0 Ultra 400GH Compact Desktop KHeavyHash Miner for Kaspa (KAS)

The 75 dB spec on a 100W device raises immediate questions. Most miners drawing 100W or less operate at 35 to 40 dB. The KS0 Ultra at 400 GH/s and 75 dB is either genuinely loud for its size or the specification is overstated. Multiple listings report lower actual noise. Ask your seller for real world noise measurements before purchasing if quiet operation matters.

Setting aside the noise question, 400 GH/s of KHeavyHash at 100W is a respectable desktop Kaspa mining device. Four times the hashrate of the original KS0 (100 GH/s, 65W) at roughly the same power efficiency per gigahash. The Ultra represents the maturation of IceRiver's entry level Kaspa platform.

19 to 20V DC input with included adapter. Universal AC input on the adapter side. Daily electricity at $0.07 per kWh: $0.17. Monthly: $5. Kaspa mining at the cost of forgetting to unplug a phone charger. The operating expense is negligible regardless of KAS price or difficulty.

The KS0 series tells the story of Kaspa ASIC evolution. KS0 at 100 GH/s launched in 2023 as the first mass market Kaspa miner. KS0 PRO doubled to 200 GH/s. KS0 Ultra quadrupled the original to 400 GH/s. Each step improved output while maintaining the compact desktop form factor. Above the Ultra tier, the KS2 Lite at 2 TH/s and 500W represents the next step requiring meaningfully more power.

Ethernet connectivity. IceRiver firmware shared across the KS product line. Standard KHeavyHash Stratum for any Kaspa pool. Compact form factor at modest weight.

IceRiver KS0 Ultra 400GH Compact Desktop Kaspa Miner

IceRiver's enhanced KS0 tier at 400 GH/s and 100W. 4x the original KS0 hashrate at the same power. 19 to 20V DC input. Listed at 75 dB which seems high for 100W. Verify actual noise with your seller.

Air cooled at 75 dB. Kaspa (KAS). IceRiver firmware. 200 x 194 x 74mm at 2.5 kg. Ethernet. 5 - 35 °C.

Industrial 75 dB requires dedicated mining space. Warehouses, containers, or isolated rooms. Not for shared environments.

IceRiver 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. 100W 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.
