AFRNDK Antminer S19J Pro 100TH/s 3050W SHA-256 ASIC mining hardware

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.
