Goldshell KA Box PRO (1.6TH)

1.6 TH/s KHeavyHash at 600W and 375 J/TH efficiency (0.375 J/GH). ±5 percent hashrate and ±5 percent power tolerance. Released June 2024 by Goldshell. 35 percent more hashrate than the original KA Box (1.18 TH/s). Dual-Mode operation: Default Hashrate Mode at 1.6 TH/s / 600W, or Low-Power Mode at reduced hashrate and power for flexibility. Mines Kaspa (KAS) primary and Sedra (SDR) as secondary KHeavyHash chain.

≤35 dB per Goldshell's official product page and every major distributor (Asic Marketplace, BT-Miners, CryptoMinerBros, Amazon). MM's product page lists 75 dB which is factually wrong. ≤35 dB is near silent operation, quieter than typical office background noise, suitable for any home environment including bedrooms, home offices, and living spaces. MM's extensive editorial content on their product page describing the KA Box Pro as "industrial noise" and not suitable for home is based on a fabricated specification and should be disregarded.

KA Box original: 1.18 TH/s, 400W, 339 J/TH, ≤35 dB. KA Box Pro: 1.6 TH/s, 600W, 375 J/TH, ≤35 dB (this product). The Pro produces 35 percent more hashrate at 50 percent more power. Per watt efficiency is slightly worse on the Pro (0.375 vs 0.339 J/GH) but absolute daily KAS production is meaningfully higher. Both products share the same compact home form factor, same ≤35 dB quiet operation, same WiFi + Ethernet connectivity with mobile app control, same Goldshell firmware ecosystem, and same universal voltage. At similar pricing differential, the Pro is the upgrade path for buyers wanting more hashrate in the same quiet home form factor.

No, not at standard electricity rates as of April 2026. MM's own calculator at $0.08 per kWh shows $0.33 daily revenue against $1.15 daily electricity cost, producing -$0.83 daily loss (-$303 annual). At $0.07 per kWh: -$0.71 daily. At $0.04 per kWh industrial rate: -$0.25 daily (still negative). Break even requires electricity below approximately $0.03 per kWh or meaningful KAS token appreciation. The KA Box Pro is a speculative KAS accumulation device at current KAS conditions, not an operational profit miner at typical electricity rates.

Goldshell's Dual-Mode feature provides two selectable operating configurations. Default Hashrate Mode: 1.6 TH/s at 600W delivering 375 J/TH efficiency. Low-Power Mode: reduced hashrate at reduced power (specific figures not disclosed on Goldshell's public documentation but typically 40-60 percent of rated power). Operators switch modes through the Goldshell mobile app or web interface. Low-Power Mode enables operation during peak electricity rate periods, thermal management during warm ambient conditions, or matching dedicated electrical capacity. This feature differentiates the Pro from the original KA Box.

100-240V universal AC wall input via the included PSU. At 600W on 120V draws approximately 5 amps (standard 15A circuit). At 240V draws approximately 2.5 amps. Compatible with any standard wall outlet worldwide. The PSU converts AC to 12V DC internal for the miner PCB. Note: Goldshell official documentation indicates PSU may not always ship included with the KA Box Pro; verify PSU inclusion with MillionMiner at purchase.

Actual miner dimensions 171 x 198 x 96 mm at 2.9 kg per Goldshell official documentation. MM's product page lists 300 x 225 x 149 mm at 2.6 kg, but these are PACKAGING dimensions and gross packaged weight, not the miner itself. Approximately the size of a shoebox or small desktop device. Fits on any desk, shelf, or bookshelf without dedicated installation. Single hand placement.

Ethernet and WiFi dual connectivity. Wired Ethernet via RJ45 port for stable data transmission. WiFi for wireless deployment flexibility. Goldshell mobile app (iOS and Android) provides remote monitoring, pool configuration, and Dual-Mode selection from your phone. Web dashboard also available via browser for desktop management. The WiFi + app combination enables consumer oriented mining management not requiring technical networking expertise.

0 to 35 degrees Celsius per Goldshell official documentation, Asic Marketplace, BT-Miners, and Amazon. MM lists 5-35°C which is slightly conservative. Humidity tolerance ≤65 percent. At 600W power draw, thermal output is approximately 2,047 BTU per hour. A small room absorbs this heat load without dedicated HVAC. The compact form factor and modest thermal output allow placement in typical residential environments.

Approximately 6-8 KAS per day at current network conditions (April 2026). Monthly production: approximately 180-240 KAS. Annual production: approximately 2,200-2,900 KAS. At current KAS price of approximately $0.02: $44-$58 annual revenue. At future price scenarios: $1 KAS = $2,200-$2,900 annual value, $5 KAS = $11,000-$14,500. The KA Box Pro economics are speculative on future KAS appreciation, not current daily profit.

E-KA1M: 5.5 TH/s, 1,800W, 50 dB (step up to higher tier home industrial). KA Box Pro: 1.6 TH/s, 600W, ≤35 dB (this product, home tier). The E-KA1M delivers 3.4x the hashrate but at 3x the power and higher noise. For quiet residential deployment, the KA Box Pro is the better fit. For buyers with dedicated mining space tolerating 50 dB and higher power capacity, the E-KA1M produces more absolute KAS. For home office or living room deployment, the KA Box Pro's ≤35 dB quiet operation is the clear choice.

IceRiver KS0 Ultra: 400 GH/s, 100W, ≤35 dB, $199 (home tier, less hashrate, less power). KA Box Pro: 1.6 TH/s, 600W, ≤35 dB (this product, 4x more hashrate, 6x more power). The KS0 Ultra is the minimum commitment home Kaspa device. The KA Box Pro produces 4x more KAS daily but at 6x the electricity cost. Per watt efficiency: KS0 Ultra at 0.25 J/GH vs KA Box Pro at 0.375 J/GH (KS0 Ultra is 50 percent more efficient per watt). For operators with cheap electricity who want more hashrate per unit, the KA Box Pro wins on absolute output. For efficiency per watt and lowest entry cost, the KS0 Ultra wins.

Kaspa (KAS) primary. Sedra (SDR) as secondary KHeavyHash chain. NiceHash compatible for Bitcoin payout alternative to direct KAS mining. The KA Box Pro is an algorithm specific device for KHeavyHash only. Not compatible with Scrypt, SHA-256, or other proof of work algorithms.

Varies by source. MM's Box Contents lists PSU included. Goldshell's official product page documentation for some retail contexts indicates PSU may be sold separately. Some distributors include PSU, others don't. Verify PSU inclusion with MillionMiner at purchase before deployment planning. If PSU is required separately, source a 12V DC PSU rated for 600W+ with 6-pin connector compatible with Goldshell hardware.

Plug power cable into 100-240V wall outlet (verify PSU is included or source separately per Q14). Connect Ethernet cable to your router or switch (or configure WiFi via Goldshell mobile app during initial setup). Find miner IP through Goldshell mobile app, router DHCP, or network IP scanner. Open Goldshell web interface or mobile app. Configure Kaspa pool URL (WoolyPooly, F2Pool, Kryptex, IceRiver's pool) and KAS wallet address. Select operating mode (Default Hashrate or Low-Power). Verify hashrate stabilizes at approximately 1.6 TH/s within 10-15 minutes.

All major Kaspa mining pools. WoolyPooly, F2Pool, Kryptex, IceRiver's pool, Herominers, 2Miners, and other Kaspa compatible pools. Standard Stratum protocol with KHeavyHash extensions. NiceHash supports the KA Box Pro for Bitcoin payout alternative to direct KAS mining.

6-month Goldshell manufacturer warranty per BT-Miners and Goldshell's standard warranty terms for Box series products. Covers manufacturing defects and hardware failures under normal operating conditions. Warranty begins from shipping confirmation date. Tampering with warranty label, improper voltage input, or use of non approved PSU may void warranty per standard Goldshell terms.

Minimal desktop device maintenance. Periodic dust wipe of two cooling fans and exterior. Monitor hashrate through Goldshell mobile app or web dashboard. Released June 2024, the KA Box Pro has approximately 22 months of field reliability data as of April 2026. No known systemic reliability issues. Consumer oriented enclosure design for home environments rather than industrial dust conditions.

Buy if: you want the upgrade path from the original KA Box (35 percent more hashrate in same quiet home form factor), you are committed to speculative KAS accumulation and want more hashrate than the IceRiver KS0 Ultra, you value Goldshell's mobile app ecosystem and WiFi + Ethernet connectivity, you have access to cheap industrial electricity (below $0.04 per kWh) for break even or positive margins, or you plan to use Low-Power Mode flexibility for electricity rate optimization. Do NOT buy if: you expect operational profit at standard electricity rates (the KA Box Pro loses money at $0.08/kWh residential), you rely on MM's incorrect 75 dB noise specification (the actual device is ≤35 dB quiet), or you are uncertain about KAS long term price appreciation. Consider the IceRiver KS0 Ultra ($199, 400 GH/s) if you want the cheapest home Kaspa entry. Consider the Goldshell E-KA1M (5.5 TH/s, 1,800W) if you want more hashrate at higher power tier.
