Bitmain Antminer L9 (17Gh)

17 GH/s Scrypt at 3,570W continuous and 0.21 J/MH efficiency. Bitmain's ±5 percent tolerance produces real world output between 16.15 and 17.85 GH/s depending on ambient temperature, power quality, and firmware version. A lower binned variant at 16 GH/s and 3,360W also ships through some channels using the same hardware with standard grade silicon.

3,570W continuous at 0.21 J/MH (210 J/GH). ±5 percent power tolerance produces real world draw between 3,392 and 3,749W. Approximately 42 percent better efficiency per gigahash than the L7 predecessor at 360 J/GH.

All Scrypt algorithm cryptocurrencies through merged mining. Primary coins: Litecoin (LTC), Dogecoin (DOGE), Bellscoin (BELLS). Additional coins: Junkcoin (JKC), Luckycoin (LKY), Pepecoin (PEP), Dingocoin (DINGO), Shibacoin (SHIC), CraftCoin (CRC), and DigiByte (DGB) through compatible pools. Combined merged mining revenue typically runs 20 to 40 percent above solo LTC at the same hashrate.

L7 at 9.5 GH/s, approximately 3,425W, and 0.36 J/MH (360 J/GH). L9 at 17 GH/s, 3,570W, and 0.21 J/MH. The L9 delivers approximately 79 percent more hashrate at essentially flat power draw and approximately 42 percent better efficiency per gigahash. For L7 operators at current difficulty, upgrading to the L9 typically pays back acquisition cost through power savings and hashrate gain within 6 to 14 months depending on electricity costs and Scrypt market prices.

SEALMINER DL1 Air at 25 GH/s, 3,725W, and 149 J/GH delivers 47 percent more hashrate and approximately 29 percent better efficiency per gigahash than the L9. The L9 delivers Bitmain's mature firmware ecosystem, broader operator familiarity, and deeper installed base for support and resale. For operators committed to Bitmain's ecosystem, the L9 remains a default choice at its tier. For operators willing to deploy second source hardware with meaningfully better efficiency, the DL1 Air offers a clear per unit advantage.

220 to 277V single phase AC input with approximately 16.2 amps at 220V continuous. Standard commercial 220 to 240V service required, or 220V outlets like those used for electric dryers and EV chargers. Cannot practically run at 110V residential since 3,570W at 120V would require approximately 30 amps. MM's page references a 100 to 240V universal range which may reflect PSU input tolerance; verify 220V+ facility power for full performance.

75 dB industrial noise from four high speed fans. Comparable to a vacuum cleaner or busy restaurant. Disruptive through walls. Requires sound isolated deployment: dedicated mining room, garage with sound isolation, basement, outbuilding, warehouse, or professional hosting facility. Not suitable for residential rooms, shared offices, or any space where humans spend extended time without hearing protection.

Major Scrypt merged mining pools accept L9 hashrate including F2Pool, Poolin, ViaBTC, Prohashing, and Litecoinpool. Prohashing and ViaBTC offer broader merge coin support including Bellscoin. Pool fees typically 0.5 to 2 percent of revenue. Configure once with LTC, DOGE, and BELLS wallet addresses and the pool distributes rewards across all supported chains automatically.

Depends on electricity cost and coin prices. At industrial electricity rates ($0.04 to $0.07 per kWh), the L9 typically remains economically viable for 2 to 3 years after deployment even with steady difficulty growth, extending with LTC/DOGE price appreciation. At residential rates ($0.10+ per kWh), the L9 may reach break even faster depending on exact conditions. L11 family deployment would displace L9 economics over the 18 to 36 month horizon as more efficient hardware reaches market saturation. Model conservatively assuming 20 to 30 percent annual network difficulty growth.

PSU included in the box with the miner. Ships with Antwire C20-P13 connector cable for PSU to miner interconnect. Some batches require a locally sourced C19 power cord rated for at least 16 amps depending on region. Verify cable requirements with MillionMiner at time of order for deployment planning.

L9 at 17 GH/s, 3,570W, 0.21 J/MH. L11 base at 20 GH/s, 3,680W, 0.184 J/MH. L11 Pro at 21 GH/s, 3,612W, 0.172 J/MH. The L11 family delivers 18 to 24 percent more hashrate at 12 to 18 percent better efficiency per megahash than the L9. Same BM1485 chip family but improved binning and revision. L9 operators upgrading to L11 typically pay back through power savings and hashrate gain within 12 to 24 months at standard electricity rates.

400 x 195 x 290 mm chassis per Antminer Distribution, CryptoMinerBros, and most distributor documentation. Weight approximately 16 kg per Mining Now. MillionMiner's page lists different dimensions (195 x 290 x 379 mm) and weight (13.5 kg) which may reflect shipping packaging or a different chassis revision. Verify physical dimensions with MillionMiner for rack planning.

Depende de voltagem, ruído e capacidade térmica. Voltagem: requer 220 a 277V para implantação prática, não padrão de 110V residencial. Casas com tomadas de aparelhos de 220V (secadores, carregadores de veículos elétricos) podem implantar com circuitos apropriados. Ruído: 75 dB excede os níveis confortáveis para residências e requer espaço dedicado para mineração (garagem, dependência, porão isolado). Térmico: 3.570W requer ventilação ou ar-condicionado. Para uma mineração doméstica silenciosa de Scrypt, o Fluminer L3 com 9,5 GH/s e 45 dB ou o Fluminer L1 Pro com 6 GH/s e 45 dB são opções adequadas.

Four high speed air cooling fans with front intake and rear exhaust. No external water loops or immersion. Facility requirements: ventilation for approximately 12,180 BTU per hour heat output, adequate intake and exhaust air, ambient temperature within specified range. For multi unit deployment, HVAC capacity must match aggregate thermal output across the fleet.

MM specifies 5 to 45 degrees Celsius at 5 to 95 percent humidity. Alternative distributor documentation varies from 0 to 40 degrees Celsius (OneMiners) to 0 to 75 degrees Celsius (CryptoMinerBros) representing different interpretations of optimal versus maximum survivable conditions. For hot climate deployment (UAE, Texas summer, Arizona), facility cooling must hold intake air below 40 degrees Celsius under peak load for stable hashrate.

Four step setup. Verify 220 to 277V single phase circuit capable of 3,570W continuous (20 amp 220V minimum). Connect PSU to miner using Antwire C20-P13 cable. Connect PSU to wall outlet using locally sourced C19 power cord rated for 16+ amps. Connect Ethernet. Find miner IP, open Bitmain web interface, configure Scrypt merged mining pool URL and LTC/DOGE/BELLS wallet addresses, change default credentials. Verify hashrate reaches 16+ GH/s within 10 minutes.

Limited third party firmware support for Scrypt ASICs compared to the SHA-256 ecosystem. Most L9 operators run stock Bitmain firmware. Some BraiinsOS style tuning projects have targeted L9 specifically, delivering modest efficiency and hashrate improvements over stock firmware at the cost of warranty voiding. Operators prioritizing firmware stability and warranty coverage should run stock Bitmain firmware.

Yes. MillionMiner hosting services accept L9 units at managed facilities with 220 to 277V single phase infrastructure. Hosting economics typically work at industrial electricity rates. Contact MillionMiner for hosting rate tiers and availability across the managed facility network.

Avaliação mista dependendo do orçamento e do perfil do operador. Prós: custo de aquisição menor do que a família L11, ecossistema de firmware Bitmain maduro com ampla experiência de operadores, receita de mineração mesclada através de LTC/DOGE/BELLS, mercado estabelecido de revenda e suporte. Contras: a família L11 oferece de 12 a 18 por cento de eficiência melhor por megahash com maior hashrate por unidade, o Bitdeer SEALMINER DL1 Air oferece 29 por cento de eficiência melhor do que o L9 com maior hashrate por unidade. Para operadores com horizontes de implantação de curto a médio prazo (1 a 2 anos) ou expansão de frota com recursos limitados, o L9 continua sendo econômico. Para operadores que estão construindo novas frotas de vários anos, atualizar para a família L11 ou Bitdeer DL1 Air normalmente oferece melhores economia por capital.
