AFRNDK AvalonMiner 1246 83TH/s SHA-256 mining hardware

AvalonMiner 1246 SHA-256 ASIC

The AvalonMiner 1246 is a Canaan-built ASIC designed for SHA-256 mining. It targets operators who want a single integrated unit that includes the power supply. The machine delivers a maximum hashrate of 83 TH/s while drawing 3420 W from a 220 V supply. It connects to the network over Ethernet and operates between -5 °C and 35 °C.

83 TH/s at 38 J/TH efficiency

At the rated 83 TH/s the unit consumes 3420 W, yielding a power efficiency of 38 J/TH. The alternative 3155 W figure represents a lower operating point that reduces output accordingly. Four 12 V 4.5 A fans move air through the chassis to keep temperatures in range, but the 75 dB noise level means the device needs a dedicated space. Continuous operation at the top hashrate requires stable 220 V input; incorrect voltage can damage the hardware.

Integrated PSU and four 12038 fans

The power supply is built into the enclosure, removing the need for an external PSU and its cabling. Four 12038 fans are pre-installed and wired to the 12 V rail, so cooling is handled out of the box. The integrated design also fixes the AC input at 16 A across 50 Hz to 60 Hz with a maximum voltage of 285 V. No extra mounting hardware or software licences are mentioned in the data.
