SHA-256 ASIC Miner for Bitcoin Operations

The AFRNDK Antminer S9j delivers a hash rate of 14.5 TH/s using 189 ASIC chips on the SHA-256 algorithm. It draws 1350 W at a rated voltage of 11.60 ~ 13.00 V and achieves a power efficiency of 93.12 J/TH. This unit is built for operators running Bitcoin or Bitcoin Cash mining workloads on 220 V to 240 V mains supply.

Three PCIe Power Connectors Per Hash Board

Each of the three hash boards requires three PCIe connectors for +12 V DC input, and all three must be connected to the PSU for the board to operate. Do not connect more than one PSU to the same hash board. The machine includes a power supply and uses Ethernet for network connection, with auto-frequency scaling and a 128 Bit memory interface.

Verify Mains Voltage and Environmental Limits

The miner requires 220 V to 240 V input and will reach 1350 W, so confirm your facility can supply this voltage range. Operating temperature must stay within 0 °C to 40 °C and humidity between 5 % RH and 95 % RH without condensation. Noise output is 76 dB from dual 12038 fans running at 6000 rpm and 4300 rpm, and the unit weighs 8 kg with dimensions of 350 mm x 135 mm x 158 mm.

Questions about this item

How do I confirm the Antminer S9j is hashing at 14.5 TH/s after setup?

Check the miner's web dashboard or your mining pool's worker page; a stable 14.5 TH/s reading and an efficiency near 93.12 J/TH show the 189 ASIC chips are all running at auto-frequency.

What comes in the box with the Antminer S9j and what must I source separately?

The unit ships with the miner housing, two 12038 fans (front 6000 rpm, rear 4300 rpm) and the control board; you must provide a 220-240 V PSU capable of 1350 W with three PCIe +12 V connectors per hashing board and an Ethernet cable.

Should I choose the 13.5 TH/s or 14.5 TH/s version of the S9j for best efficiency?

The 14.5 TH/s model delivers 93.12 J/TH at 1350 W, so it provides higher throughput per watt than the lower-rated 13.5 TH/s variant while using the same 189-chip design.
