Goldshell CK Box (1.05TH)

1.05 TH/s Eaglesong at 215W and 205 J/TH efficiency. ±5 percent tolerance on both hashrate and power. Single operating mode with no firmware selectable low power option (that was added with the CK Box II). This is Goldshell's first generation desktop CKB miner released July 2021, now superseded by the CK Box II at exactly double the hashrate.

CK Box: 1.05 TH/s at 215W, single mode. CK Box II: 2.1 TH/s at 400W default, 1.54 TH/s at 260W low power. The CK Box II exactly doubles hashrate and adds dual power mode. The original CK Box draws substantially less power (215W versus 260 to 400W) and costs approximately half the monthly electricity. For maximum CKB output, the CK Box II wins. For minimum monthly running cost, the CK Box wins at $12.40 versus $15.01 to $23.04 depending on CK Box II mode. If both are available at similar pricing, the CK Box II is the straightforward upgrade.

CK Box at 1.05 TH/s and 215W (single mode). BM-N3 Mini at 1.8 / 1.3 TH/s and 295 / 185W (dual mode). The BM-N3 Mini delivers 71 percent more hashrate in default mode and offers dual power flexibility the CK Box lacks. The CK Box draws less power in its single mode (215W) than the BM-N3 Mini's low power mode (185W) while still producing 81 percent of the BM-N3 Mini's low power hashrate (1.05 versus 1.3 TH/s). For the absolute cheapest electricity bill, the CK Box wins. For more hashrate with mode flexibility, the BM-N3 Mini wins.

At standard residential rates, no. At $0.08 per kWh: approximately $0.10 daily revenue, $0.41 daily electricity, -$0.31 daily loss. Mining CKB on the CK Box is a speculative accumulation strategy at approximately $12.40 monthly electricity. The daily loss is negligible. CKB's Binance listing provides a more credible exit for accumulated tokens than most niche mining targets. Low Power SC mode on other devices costs more monthly; the CK Box holds the cheapest CKB desktop mining position.

Nervos is a Layer 1 proof of work blockchain using the Eaglesong algorithm, designed as a security and settlement layer for Layer 2 scaling. Uses a cell model inspired by Bitcoin's UTXO. The RGB++ protocol bridges Bitcoin assets to Nervos for Layer 2 interoperability. CKB trades on Binance, Crypto.com, and Gate.io with meaningful liquidity. The combination of PoW consensus, Bitcoin bridge, and Binance listing positions Nervos differently from most altcoin mining targets.

35 dB from a single cooling fan. Inaudible from the next room. Consistent with the Goldshell Box series acoustic standard. The original CK Box uses one fan versus the CK Box II's two fans, both achieving 35 dB. Operates in bedrooms, offices, apartments, and shared spaces without detection.

Universal 100 to 240V through external PSU (not included). At 215W the PSU draws approximately 2 amps at 110V. Fits any standard residential outlet worldwide. No circuit planning needed. Monthly electricity at $0.08 per kWh: approximately $12.40, the cheapest monthly running cost in the desktop Eaglesong ASIC category.

No. The CK Box ships without PSU per most distributor documentation (MiningCrypto title explicitly states "Without PSU"). Verify with MillionMiner whether they bundle a PSU. If not included, source a compatible external PSU rated 250W+ with the correct connector. Some Amazon and distributor listings offer 750W PSU bundles as an optional configuration.

175 x 150 x 84 mm při 2 kg. Mírně menší než CK Box II (178 x 150 x 84 mm). Přibližně velikost tlusté papírové knihy. Jeden ventilátor. Vnější zdroj napájení přidává samostatný prostor. Stojí na jakémkoli stole, polici nebo pultu vedle spotřební elektroniky.

5 to 35 degrees Celsius at 5 to 95 percent humidity per Bitcoin Merch and MiningCrypto. The 35 degree ceiling means warm climate deployments need air conditioned space during hot months. At 215W heat output (approximately 733 BTU per hour), the CK Box produces less heat than most desktop computers, causing negligible thermal concern in any ventilated space.

Nervos (CKB) is the primary and by far the largest Eaglesong network. NiceHash Eaglesong marketplace provides an alternative selling hashrate for Bitcoin. No other Eaglesong networks currently attract meaningful mining participation. Unlike the HS series which mines dual algorithms (Handshake and Siacoin), the CK Box is single algorithm only.

Three step setup. Connect external PSU to CK Box and plug PSU into any 100 to 240V outlet. Connect Ethernet cable to router or switch. Find miner IP through Goldshell finder tool, router DHCP, or network scanner. Open web interface, configure Eaglesong pool URL and CKB wallet address. Goldshell mobile app supports iOS and Android configuration. Total setup approximately 10 minutes.

Major CKB Eaglesong pools including F2Pool, DxPool, 2miners, and SparkPool variants accept CK Box hashrate. NiceHash Eaglesong marketplace provides a Bitcoin payout alternative. Pool fees typically 1 to 3 percent. At 1.05 TH/s, pool mining is the only practical approach. Solo mining at this hashrate produces extremely infrequent block finds.

Yes. At 215W each, a standard 15 amp 110V circuit (1,800W capacity) supports eight CK Box units (1,720W total). Configure all units to the same pool and wallet. Eight units produce approximately 8.4 TH/s aggregate, exceeding the CK Lite (6.3 TH/s, 55 dB) at whisper quiet collective noise. The CK Box's low per unit power draw maximizes units per circuit compared to the CK Box II (4 units per circuit) or BM-N3 Mini (6 units per circuit).

Yes, with caveats. The CK Box is simple to set up (plug in PSU, Ethernet, configure pool), draws minimal power (215W), runs silently (35 dB), and introduces beginners to ASIC mining concepts (pool configuration, wallet setup, hashrate monitoring) at very low running cost ($12.40 monthly). The caveat: it is not profitable at current conditions. Beginners should understand they are spending $12.40 monthly on electricity to accumulate CKB tokens speculatively, not generating daily income. The Binance listing for CKB makes this a more practical first mining experience than niche tokens with limited exchange access.

Minimal. Quarterly dust wipe of the compact chassis and single fan grille. Monitor hashrate through Goldshell web interface or mobile app for degradation. No coolant, filters, or internal servicing. Released July 2021, units have nearly five years of field reliability data, among the longest operational track records of any currently distributed ASIC mining device.

MillionMiner technically accepts CK Box units, but hosting economics at 215W generating approximately $0.10 daily revenue make the arrangement impractical. Hosting fees would exceed mining revenue at any rate tier. The CK Box is purpose built for self hosted desktop deployment.

Three scenarios. Price: if the original CK Box is available at deep discount as cleared first generation inventory, the lower capital outlay may justify the lower hashrate for budget constrained buyers. Power: 215W is the lowest power CKB desktop option, costing $12.40 monthly versus $15 to $23 for alternatives. Circuit density: eight CK Box units fit on one 15 amp circuit versus four CK Box II units, useful for multi unit fleet building on limited electrical infrastructure.

Only in specific scenarios. This is first generation July 2021 hardware without dual power mode. It loses approximately $0.31 daily at standard electricity rates. Buy the CK Box if: it is available at meaningful discount versus the CK Box II and you want the absolute lowest capital and monthly cost entry into CKB mining, you are building a multi unit fleet and need maximum units per circuit at 35 dB, or you want a functional piece of Goldshell Nervos mining history. Check CK Box II availability and pricing first. The CK Box II delivers double the hashrate with dual power mode flexibility.

Direct upgrade: Goldshell CK Box II (2.1 TH/s, dual mode, double hashrate). Competing manufacturer at same tier: iBeLink BM-N3 Mini (1.8 TH/s, dual mode). Within Goldshell CK family for scaling: CK Lite (6.3 TH/s, 55 dB), CK5 (12 TH/s, 80 dB), CK6 (19.3 TH/s, 80 dB). For cross algorithm niche mining at same 35 dB tier: Goldshell KA Box (1.18 TH/s Kaspa), Goldshell HS Box II (460 GH/s HNS / 1,200 GH/s SC), Goldshell AL Box II Pro (950 GH/s Alephium), Goldshell KD Box II (5 TH/s Kadena). For Bitcoin at home tier: Bitaxe Gamma 601 (1.2 TH/s SHA-256).
