AFRNDK Antminer S19J Pro 100TH/s SHA-256 ASIC

This ASIC miner is built for Bitcoin mining using the SHA-256 algorithm. It delivers a hash rate of 100 TH/s while drawing 3050 W of power. The unit operates on a 220 V supply and produces a noise level of 80 dB. It targets operators who need dedicated SHA-256 hardware for BTC mining.

Upgrade from S17 T19 S19 series to 100 TH/s

The S19J Pro replaces earlier models such as the S17, T19 and S19 with a higher hash rate and improved efficiency of 0.031 J/Gh. New firmware reduces start-up time and improves stability during continuous operation. The jump is worth it when electricity cost per kilowatt-hour makes the lower energy per gigahash decisive. Four fans manage thermal load at the rated 3050 W power draw.

220 V input constraint and 80 dB acoustic limit

The miner requires a 220 V input; incorrect voltage can damage the hardware. At 80 dB the noise level suits dedicated facilities rather than office or home environments. Efficiency of 0.031 J/Gh sets the practical floor for power cost calculations. No other interface or protocol limitations are specified for this SHA-256 ASIC device.

Questions about this item

What input voltage does the AFRNDK Antminer S19J Pro require?

The miner requires 220 V input; connecting it to a different voltage can damage the unit.

What is the correct firmware update procedure for the S19J Pro and which step is most often missed?

Apply the new firmware design through the controller interface, then restart the miner; the step most often missed is the mandatory reboot after flashing.

When should the four cooling fans be inspected or replaced on this 3050 W ASIC miner?

Inspect all four fans every few months for dust build-up or bearing noise; replace any fan that spins unevenly or exceeds the 75 dB operating level.
