Antminer S19j Pro+
Improved S19j Pro with better efficiency, same infrastructure requirements
DCENT_OS Compatible
DCENT_OS is custom firmware developed by D-Central Technologies specifically for home miners. It transforms this miner with whisper-quiet fan profiles, 120V North American outlet support, auto-tuning for maximum efficiency, heater mode integration, and a clean web dashboard for monitoring.
Miners running DCENT_OS score higher on our Home Mining Assessment because the firmware is purpose-built to make industrial hardware livable in residential spaces.
Learn More About DCENT_OS →Professional-Grade Miner
This miner draws 3,355W and produces 75 dB of noise — it is designed for dedicated mining environments, not living spaces. Professional-grade miners deliver the highest hashrate and revenue per unit but require proper infrastructure: a 240V circuit, adequate ventilation or exhaust ducting, and a space where noise is not a concern (garage, basement, warehouse, or outdoor enclosure).
However, this miner is compatible with DCENT_OS — D-Central's custom firmware that adds whisper-quiet fan profiles and 120V North American outlet support. With DCENT_OS installed, this industrial miner can be transformed for home use.
Heater-Class Miner
At 3,355W, this miner outputs approximately 11447.3 BTU/hr of heat — equivalent to a standard electric space heater. Every watt consumed by an ASIC miner is converted to heat with 100% efficiency, making it a space heater that also mines Bitcoin.
During heating season, miner heat can offset part of the heat a room would otherwise need from another electric heater. The economics depend on your electricity rate, room heat demand, BTC price, network difficulty, and noise constraints.
