Antminer L9 15GH Scrypt ASIC Miner

The Antminer L9 delivers a typical hashrate of 15 GH/s for the Scrypt algorithm, making it suitable for mining Dogecoin and other compatible currencies. It operates on 220-277V AC input with a built-in power supply and draws up to 3150 W at the wall. Typical power efficiency is 210 J/GH with actual values fluctuating by ±5%. The unit weighs 14.2 kg and measures 400×195×290 mm.

Upgrade from lower-output Scrypt miners

Replacing older Scrypt hardware with the L9 raises hashrate to 15 GH/s while keeping power efficiency at 210 J/GH, reducing energy cost per coin when electricity rates are stable. The jump is worth it when the higher output offsets the 3150 W draw and the 75 dBA noise level fits the operating environment. Hashrate may vary by ±3% and power by ±5% in practice.

Installation and common issues

Connect the RJ45 Ethernet 10/100M port to the network and supply 220-277V AC at up to 20 A single-phase; wrong input voltage may damage the server. Ensure ambient temperature stays within -20°C to 45°C and humidity 10-90% RH non-condensing at altitudes up to 2000 m. Fans run at max RPM under peak load, so plan airflow and noise isolation accordingly.

Questions about this item

What clearance does the 400×195×290 mm unit need for intake and exhaust airflow?

Allow at least 100 mm free space at the front fan wall and 150 mm at the rear exhaust so the 75 dBA airflow can move through the -20 to 45 °C operating envelope without recirculation.

Which steps must be followed when commissioning the miner on a 220–277 V single-phase supply?

Verify the circuit breaker is rated for 20 A, connect the IEC cord to the built-in PSU before powering on, then link the RJ45 Ethernet 10/100M port; skipping the breaker check is the step most often missed.

When should the dual cooling fans be inspected or replaced under continuous 3150 W load?

Plan a visual check every 180 days; if bearing noise rises above the baseline 75 dBA or RPM drops below the max-condition spec, swap both fans to keep the 210 J/GH efficiency target.
