Understand the hardware before you power it on.
Practical guides for selecting, powering, ventilating and operating ASIC hardware without turning product pages into profit promises.
How to choose an ASIC
Start with the algorithm, available voltage, power budget, acceptable noise and where the machine will run.
First startup
Suitable electrical circuit, airflow, Ethernet, IP discovery, pool, wallet and monitoring of the first cycles.
Calculate real power cost
Nominal power × operating hours × electricity price. Our calculator handles the basic arithmetic without inventing mining income.
Open calculator →What to check on used hardware
Serial number, chassis, fans, hashboards, temperatures, logs and hashrate stability.
Noise, heat and airflow
A multi-kilowatt ASIC converts almost all consumed electricity into heat. Air extraction is part of the project.
Cleaning and monitoring
Dust, temperatures, fans and logs are the first indicators to monitor for stable operation.
Before buying
Compare constraints, not just hashrate.
A more powerful model is not automatically better if your electrical installation, airflow or electricity cost does not support it.
