"Double New Chips, Double the Miracle !"
🔥Pre-orders Open Now! Shipping on September 17th.
Introducing the Bitaxe Naja Duo (Model 1201) —the first Bitaxe Miner powered by Bitmain’s BM1373 chips: it delivers a hashrate of up to 4.4 TH/s with a power consumption of just 42W, achieving an efficiency of 9.5 J/TH!
By integrating two BM1373 chips (from the same generation as the S23 series) onto a single PCB, it achieves a hashrate comparable to 4-chip BM1370 designs while maintaining the same 42W power consumption as the Bitaxe GT 801.
Key Features
-
Dual BM1373 Hashrate: Equipped with two BM1373 ASIC chips to deliver 4.4 TH/s stock at ~42W and approximately 9.5 J/TH efficiency. Switch to overclock profiles up to 8 TH/s at ~92W for more solo lottery power.
-
Per-Chip Thermal & Two-Phase Power: Bitaxe Naja Duo adds independent temperature monitoring for each ASIC and a 2-phase TI TPS546024A VRM, holding OC.
-
Dual-cooling solution: features a Thermalright AXP90-X47 cooler paired with an ultra-slim 92mm x 15mm PWM fan; the fan has a rated airflow of 42.58 CFM and a maximum noise level of 22.4 dBA.
- ESP-miner + AxeOS: Flash and update over USB-C or right from the browser — no black box, ever.
-
Clear 1.9" Color LCD: A 170 × 320 display shows IP address, hashrate, temperature and best difficulty at a glance.
