IceRiver KS0 ICERIVER KAS KS0

100 GH/s KHeavyHash at 65W and 0.65 J/GH (650 J/TH) efficiency. ±10 percent hashrate and ±10 percent power tolerance. The first mass market Kaspa ASIC miner, released June-July 2023 by IceRiver. Now superseded by KS0 PRO (200 GH/s) and KS0 Ultra (400 GH/s) but retains historical significance as the device that launched dedicated Kaspa ASIC mining. Mines Kaspa (KAS) and Sedra (SDR).

Univerzální síťový vstup 100-240V AC prostřednictvím přiloženého napájecího adaptéru. Těžební stroj funguje interně na 12V DC. Stránka produktu MM uvádí „19-20V DC“, což je nesprávné — to je specifikace KS0 Ultra, nikoliv původního KS0. Každý distributor zdroj potvrzuje interní napětí 12V DC pro KS0 (Asic Marketplace, Newegg). Přiložený adaptér přijímá jakékoli standardní zásuvky na světě a dodává 12V DC k těžaři. Unikátně KS0 také podporuje napájení přes USB Typ-C jako alternativní vstup (ne současně s DC adaptérem).

The KS0 is the first mass market dedicated Kaspa mining ASIC ever shipped. Before the KS0, Kaspa mining required GPU rigs (graphics cards with KHeavyHash software), which had poor efficiency (10-50 W per GH versus the KS0's 0.65 W per GH, 15-75 times worse efficiency). The KS0 proved that KHeavyHash ASIC silicon was viable and economically competitive. After its June-July 2023 launch, the entire Kaspa mining industry transformed: GPU miners exited, ASIC miners entered, and network hashrate grew substantially. The KS0 occupies a similar historical position in Kaspa mining as the Bitmain S1 occupies in Bitcoin mining — the device that launched the industry.

No, not at standard electricity rates as of April 2026. MM's own calculator at $0.08 per kWh shows $0.02 daily revenue against $0.12 daily electricity cost, producing -$0.10 daily loss. Annual loss at $0.08/kWh: approximately -$36. Even at $0.02 per kWh (essentially free electricity), the KS0 is approximately break even. The economics are worse than the KS0 Ultra because the 100 GH/s hashrate is quadrupled to 400 GH/s on the Ultra at only 1.5x power. The KS0 is not a practical operational mining device at current Kaspa market conditions.

KS0 Ultra unless you have a specific reason to choose the original KS0. The Ultra produces 4x the hashrate (400 GH/s vs 100 GH/s) at 1.5x the power (100W vs 65W), delivering 2.6x better efficiency (0.25 J/GH vs 0.65 J/GH) and 4x more daily KAS production. At comparable pricing ($199 for Ultra versus whatever discount the original KS0 commands on secondary markets), the Ultra is the clear choice for operational mining. The original KS0 is only correct if you want the historical first Kaspa ASIC specifically, need the absolute lowest power draw (65W), or can acquire the KS0 at steep discount on secondary markets.

KS0 PRO (200 GH/s, 100W, 0.50 J/GH): doubled the original KS0's hashrate at slightly more power. The PRO produces 2x more Kaspa at similar per watt efficiency. For current operational mining, both are superseded by the KS0 Ultra which produces 2x the PRO's hashrate at the same 100W power. The PRO is the middle tier historical option. The Ultra is the current tier.

KS0 (100 GH/s, 65W, June-July 2023, this product): original. KS0 PRO (200 GH/s, 100W, late 2023/early 2024): doubled hashrate. KS0 Ultra (400 GH/s, 100W, May 2024): quadrupled original hashrate at same power. Each generation improved efficiency by approximately 2x. KS0: 0.65 J/GH. KS0 PRO: 0.50 J/GH. KS0 Ultra: 0.25 J/GH. Above the KS0 family: KS2 Lite (2 TH/s, 500W, industrial step), KS5L (12 TH/s, industrial), KS7 (30 TH/s, industrial flagship). For serious Kaspa mining operations, the industrial tier is where operational profit becomes meaningful.

40 dB, quiet operation comparable to a library or soft conversation. Suitable for any residential environment including bedrooms, home offices, and living spaces. Asic Marketplace lists 10 dB ultra-low for some KS0 batches. The 40 dB figure on MM's page is a reasonable middle estimate. At 65W power draw (similar to an efficient desktop monitor), thermal output is minimal and fan RPMs stay low during typical operation.

The KS0 supports dual power input options. Primary: 12V DC barrel jack via the included power adapter (accepting 100-240V AC wall input). Alternative: USB Type-C power delivery directly to the miner. The two power inputs must NOT be used simultaneously per IceRiver documentation. USB-C requires sufficient wattage capacity (at least 65W USB-C PD compatible source). This dual input flexibility is unusual in ASIC mining hardware and can enable specific deployment scenarios where USB-C power delivery is more practical than DC barrel jack adapters.

200 x 194 x 74 mm at 2.5 kg. Approximately the size of a small desktop speaker or wireless router. Fits on any desk, shelf, or bookshelf without dedicated installation. Single hand placement. Newegg lists weight as approximately 2 kg which is close to 2.5 kg figure; minor variance across sources.

0 to 35 degrees Celsius per IceRiver documentation and every major distributor (CryptoMinerBros, Newegg, Zeus Mining, Asic Marketplace). MM lists 5-35°C which is slightly conservative. 10-90 percent humidity tolerance. At 65W power draw, thermal output is minimal and the KS0 operates well within specifications in normal room temperatures. Newegg lists humidity tolerance up to 5-95 percent for some batches.

Approximately 0.4-0.5 KAS per day at current network conditions. Monthly production: approximately 12-15 KAS. Annual production: approximately 150-180 KAS. At current KAS price of approximately $0.02: annual KAS value $3-$4. This is substantially less than the KS0 Ultra (which produces 4x more KAS) or any industrial Kaspa miner. The $199-$400 historical acquisition price does not pay back through daily mining revenue at current KAS conditions.

Yes. The included power adapter accepts 100-240V AC wall input and delivers 12V DC to the miner. Zeus Mining confirms "we will provide you with an official KS0 power supply, no need for you to purchase it separately." MM's Box Contents also lists PSU included. Standard AC power cable included. Connect directly to any worldwide wall outlet without voltage concerns.

Simple residential setup. Plug the 12V DC power adapter into any 100-240V wall outlet (or connect via USB Type-C alternate power). Connect Ethernet cable from KS0 to your router or switch. Find miner IP through IceRiver's companion app, router DHCP, or network IP scanner. Open IceRiver web interface in your browser. Configure Kaspa pool URL (WoolyPooly, F2Pool, Kryptex, IceRiver's pool). Configure your KAS wallet address. Verify hashrate stabilizes at approximately 100 GH/s within 5-10 minutes. Total setup approximately 15-30 minutes.

All major Kaspa mining pools. WoolyPooly, F2Pool, Kryptex, IceRiver's own pool, Herominers, 2Miners, and other Kaspa compatible pools. Standard Stratum protocol with KHeavyHash extensions. NiceHash supports the KS0 for Bitcoin payout alternative to direct KAS mining (though small hashrate limits NiceHash economic relevance).

365-day IceRiver manufacturer warranty from shipping date per IceRiver Store official documentation. Covers manufacturing defects and shipping damage. Warranty applies only to the original purchaser. Device modifications void warranty. If the unit arrives damaged, IceRiver replaces it and covers replacement shipping costs. Among the longer warranties in the ASIC mining industry.

Yes. At 65W per unit, a standard 15 amp 120V residential circuit (1,800W capacity) supports up to 27 units. 27 KS0 units produce 2.7 TH/s aggregate, approximately equivalent to one IceRiver KS2 Lite at industrial power. For home operators with available outlet capacity, multi unit deployment is feasible though economically marginal at current KAS prices. Each unit connects independently via Ethernet.

IceRiver KS0 PRO (200 GH/s, 100W, middle tier home), IceRiver KS0 Ultra (400 GH/s, 100W, peak home tier), IceRiver KS2 Lite (2 TH/s, 500W, entry industrial), IceRiver KS5L (12 TH/s, industrial), IceRiver KS7 (30 TH/s, industrial flagship). For buyers moving up from the KS0, the KS0 Ultra at $199 is the natural upgrade path within the home desktop form factor. For meaningful operational Kaspa mining, the industrial tier (KS5L, KS7) delivers the only economics that actually work at standard electricity rates.

Buy only in specific narrow cases. Consider the KS0 if: you are a cryptocurrency mining hardware collector and want the first Kaspa ASIC ever shipped for historical significance, you need the absolute lowest power draw Kaspa mining device (65W) for specifically power constrained deployment, or you can acquire the KS0 at steep discount ($50-$100) on secondary markets where the economics may work at cheap electricity. Do NOT buy the KS0 at full retail pricing when the KS0 Ultra ($199, 4x hashrate, 2.6x better efficiency) is available. Do NOT buy the KS0 for operational profit at standard electricity rates (the KS0 loses money at $0.08/kWh). Most buyers should choose the KS0 Ultra instead.
