You do not need to buy anything to start. The equipment hub explains what the parts in a normal computer do when they mine, so you can judge what you already have before spending a penny.

Your first steps

  1. Identify your CPU and GPU model and look up their general capabilities.
  2. Check your power supply has headroom before running hardware at full load.
  3. Make sure cooling and airflow are adequate for sustained use.
  4. Start with one machine and measure before adding more.
