Goldshell Al Box 3 (1.25Th)

1.25 TH/s Blake3 at 600W and 0.48 J/GH efficiency on Goldshell's silent home tier Alephium mining chassis. ±5 percent hashrate and ±10 percent power tolerance per Goldshell official documentation. Released September to October 2024 as the third generation AL Box and the first family member to cross the terahash hashrate threshold. The highest hashrate within the silent home tier AL Box family lineup, sitting above the AL Box 2 (720 GH/s) and AL Box II Plus (1 TH/s) within the family.

Same silent home tier deployment profile, same Goldshell firmware ecosystem, same residential-friendly form factor, but substantially more hashrate at slightly better efficiency. The AL Box 3 delivers 1.25 TH/s versus the AL Box 2's 720 GH/s, drawing 600W versus 360W with 4 percent better efficiency (0.48 vs 0.5 J/GH). 73 percent more hashrate at 67 percent more power consumption. For buyers wanting maximum hashrate within the silent home tier AL Box family, the AL Box 3 is the upgrade path. For buyers prioritizing minimum acquisition cost or smaller incremental power consumption, the AL Box 2 remains the practical entry point. Both units face the same Alephium network economics challenges at current network difficulty conditions.

The AL Box 3 at 1.25 TH/s and 600W (released September to October 2024) and the AL Box II Plus at 1 TH/s and 480W (released October 2025) both sit at the top of Goldshell's silent home tier Alephium lineup with identical 0.48 J/GH efficiency. The AL Box 3 delivers 25 percent more hashrate at 25 percent more power consumption, with the AL Box II Plus offering newer firmware features and potentially WiFi support that the AL Box 3 does not include. Per gigahash electricity cost is identical between the two units. The AL Box 3 wins on absolute output per chassis. The AL Box II Plus wins on newer manufacturing batch with potentially better long term reliability data and feature support. Both face the same Alephium network economics conditions.

Alephium is a Layer 1 sharded blockchain launched in late 2021 that uses Proof of Less Work (PoLW) consensus, an energy-efficient alternative to traditional Proof of Work. Alephium pairs PoLW with the Blake3 mining algorithm and combines a stateful UTXO model with smart contract programmability via a custom virtual machine. The architecture aims to blend Bitcoin's security model with Ethereum's programmability. Mining Alephium means computing Blake3 cryptographic hashes for the network across Alephium's sharded chain architecture, supporting transaction validation in exchange for ALPH token rewards. Operators mine Alephium for direct ALPH accumulation, exposure to the sharded blockchain and PoLW consensus thesis, and diversification beyond established proof of work chains like Bitcoin.

Honestly, no, at current Alephium network conditions and typical electricity rates. MillionMiner calculator at $0.08 per kWh: $0.19 daily revenue, $1.15 daily electricity cost, approximately -$0.96 daily loss. At $0.05 per kWh industrial rate: approximately -$0.53 daily loss. At $0.04 per kWh: approximately -$0.39 daily loss. At $0.02 per kWh: approximately -$0.10 daily, near break even. Break even electricity rate at current Alephium network conditions is approximately $0.013 per kWh, below any commercially available electricity rate globally. The AL Box 3 is currently unprofitable for direct mining revenue at any realistic electricity rate. This is the honest reality of current Alephium network conditions, not a reflection of AL Box 3 hardware quality. Buyers should approach the AL Box 3 as an ALPH accumulation device positioned for long term Alephium network growth, not as an immediate profit generator.

Three specific buyer profiles can rationally purchase the AL Box 3 today despite challenging current direct profit economics. First: ALPH accumulators positioning for long term Alephium network growth, treating the hardware as an ALPH acquisition vehicle at less than spot market price (the daily ALPH yield represents accumulation that pays off if ALPH appreciates 5 to 10 times from current conditions). The AL Box 3's higher hashrate compared to the AL Box 2 means proportionally more ALPH accumulated per unit time. Second: home miners wanting maximum AL Box family hashrate within the silent home tier deployment profile without scaling to the higher noise E-AL1M (4.4 TH/s, 45 dB) or AL Max (8.3 TH/s, 55 dB) industrial units. Third: existing Alephium miners adding chassis density to current fleets at minimal incremental infrastructure cost.

100 to 240V universal AC input via the included PSU. At 110V the unit draws approximately 5.5 amps continuous. At 220V approximately 2.7 amps. Compatible with any standard residential or commercial electrical outlet worldwide including US 110V, US 220V, European 230V, and Asian 220V. No dedicated 220V circuits, no industrial three phase service, no special wiring required. The universal voltage flexibility makes the AL Box 3 deployable in any residential setting without electrical infrastructure modifications. The 600W power draw fits comfortably within any standard 15A or 20A residential circuit.

Goldshell official specification: ≤35 dB from dual cooling fans at 4,500 RPM. Some real-world distributor measurements range 35 to 45 dB at peak load conditions, with variation likely reflecting batch differences or environmental measurement methodology. At the Goldshell official 35 dB specification, the AL Box 3 is comparable to a quiet library, soft rainfall, or rustling leaves, suitable for deployment in living rooms, bedrooms, home offices, or any standard residential setting without sound isolation considerations. Even at the upper distributor measurement range of 45 dB, the AL Box 3 remains in the residential-friendly deployment tier comparable to a quiet refrigerator. Substantially quieter than industrial Bitcoin mining hardware (typically 75 dB) or industrial Aleo hardware (70 to 85 dB).

198 x 150 x 87 mm miner dimensions at 3.8 kg net weight per MillionMiner spec data. Distributor sources show some variation in reported specifications, with weight ranging 2.5 to 3.76 kg and dimensions varying across sources, likely reflecting batch differences or measurement methodology. Compact desktop format approximately the size of a small router or large hardback book. Fits on any shelf, desk, or small mining rack without dedicated infrastructure. Single hand placement and movement. The AL Box 3 maintains the compact deployment philosophy that defines the AL Box family while delivering the highest hashrate within the family lineup.

5 to 35 degrees Celsius operating range at 5 to 65 percent humidity tolerance per Goldshell official documentation. Tighter temperature range than higher tier industrial mining hardware which typically rates to 45 degrees Celsius. The 600W power draw produces approximately 2,047 BTU per hour of heat output, easily absorbed by a typical residential room with normal ventilation. For deployment in hot climates such as the UAE, Texas summer, Arizona, or tropical regions, ambient cooling infrastructure should hold intake air below 30 degrees Celsius at peak load to maintain consistent hashrate and component longevity. The 5 to 35 degrees Celsius range is sufficient for most residential indoor deployment scenarios with adequate ventilation.

Alephium (ALPH) is the primary target via the Blake3 algorithm. Other Blake3-based cryptocurrencies could theoretically be mined if pool support exists, though Alephium is by far the dominant Blake3 mining target. The AL Box 3 cannot mine Bitcoin (SHA-256), Litecoin (Scrypt), Kaspa (KHeavyHash), Ethereum Classic (Ethash), Aleo (zkSNARK), Monero (RandomX), or any other proof of work algorithm outside Blake3. The algorithm specificity is the trade off for the AL Box 3's efficiency advantage over GPU rigs. Operators considering the AL Box 3 should be committed to Alephium as the long term position before purchasing.

Yes. The AL Box 3 ships with an integrated PSU sized for the 600W rated load, along with power cables and quick start guide. Box contents per MillionMiner: AL Box 3 unit, power supply unit (PSU), power cables, and quick start guide. Contents may vary by batch with exact items listed in order confirmation. The integrated PSU eliminates external power brick sourcing decisions and connector compatibility concerns. The included 10A power cable supports the universal 100 to 240V voltage range.

Standard ASIC setup. Step one: connect the included PSU to the miner and plug into any standard 100 to 240V wall outlet. Step two: connect Ethernet cable to the router or network switch (Ethernet-only connectivity per Goldshell official documentation; some distributor sources mention WiFi support, verify with manufacturer if WiFi deployment is required). Step three: find the miner IP through the router DHCP assignment table or network IP scanner tool. Step four: open the Goldshell web interface in a browser, configure Alephium pool URL and ALPH wallet address, change default credentials immediately for security. Step five: verify hashrate stabilizes at approximately 1.25 TH/s within 10 to 15 minutes of startup. Goldshell's standard firmware and management interface handle pool configuration and monitoring through any modern web browser on the local network.

Major Alephium mining pools accept AL Box 3 hashrate including HumPool, NiceHash, Kryptex, Lolminer Pool, Herominers, IceRiverMining, K1Pool, F2Pool, and dedicated Alephium pools. Pool fees typically range from 0.5 to 2 percent of revenue depending on pool business model. Standard Stratum protocol with no hardware restrictions on pool selection. Verify pool specifics before deployment including minimum payout thresholds, hashrate reporting accuracy, and Alephium network support. The AL Box 3's 1.25 TH/s hashrate combined with current Alephium network difficulty means single unit deployments still take meaningful time to reach pool minimum payout thresholds at some pools.

180-day Goldshell factory warranty (referenced as 6 months in Goldshell official documentation) starting from shipping confirmation date. Covers manufacturing defects and hardware failures under normal operating conditions. Tampering with warranty seal, use of incompatible PSU, exceeding rated voltage input, or physical damage from shipping voids coverage. Warranty claims processed through MillionMiner support with direct Goldshell channel escalation as needed. Goldshell also provides post-warranty paid repair services.

Minimal residential-format ASIC maintenance. Quarterly dust cleaning of the dual fan intakes prevents thermal throttling and premature fan bearing wear. The 4,500 RPM fans operate at moderate speed compared to industrial mining hardware, contributing to longer expected fan bearing lifespan. Annual fan bearing inspection with replacement if bearing noise develops. Monitor hashrate continuously through the Goldshell web interface. The AL Box 3 has approximately 18 months of field reliability data as of April 2026 with no known systemic reliability issues. The 600W thermal load means dust accumulation affects performance more slowly than higher power industrial devices, so quarterly cleaning is sufficient under typical residential dust conditions.

Yes, though current Alephium network economics make hosting questionable for the AL Box 3. At MillionMiner's standard hosting rates: hosting fees plus electricity often exceed the AL Box 3's daily revenue under current network conditions. Self deployment at home electricity rates produces equivalent or better economics for buyers willing to manage the unit at home. Given the AL Box 3's residential-friendly form factor (≤35 dB silent per Goldshell spec, 600W power, universal voltage, 3.8 kg compact desktop), home deployment is the more practical path for most buyers. Hosting becomes more attractive if Alephium network conditions improve substantially or if the buyer specifically wants to avoid all home deployment management overhead. Contact MillionMiner for current hosting rates and to discuss whether hosting makes economic sense for AL Box 3 deployment.

Different deployment tiers with different infrastructure requirements. The AL Box 3 at 1.25 TH/s and 600W is silent home tier hardware deployable in residential settings. The Goldshell E-AL1M at 4.4 TH/s and 1,800W operates at 45 dB and requires more demanding deployment infrastructure. The Goldshell AL Max at 8.3 TH/s operates at 55 dB and requires industrial deployment. The Bitmain Antminer AL1 Pro at 16.6 TH/s and 3,510W requires full industrial deployment infrastructure. For buyers with home or small office deployment requirements and noise sensitivity, the AL Box 3 is the practical maximum. For buyers with industrial deployment infrastructure, the higher hashrate units deliver better total economics per unit despite all units facing the same challenging Alephium network conditions.

Buy the Goldshell AL Box 3 only if you fit one of these profiles: long term ALPH accumulator who believes Alephium network value will grow 5 to 10 times from current conditions over the next 2 to 3 years and wants to acquire ALPH at less than spot market price through mining; home miner wanting maximum AL Box family hashrate within the silent home tier deployment profile without scaling to higher noise industrial Alephium hardware; existing Alephium miner adding chassis density to current fleets at minimal incremental infrastructure cost. Avoid the AL Box 3 if you are seeking immediate profitable mining revenue, you have no specific Alephium investment thesis, you cannot afford the daily electricity loss as a long term position cost, you would prefer the lower power AL Box 2 for less daily electricity exposure, or you are uncertain about Alephium's long term network viability since the hardware is locked to the Blake3 algorithm with no coin switching flexibility.
