Reference Information

Power Formulas

  • Power (W) = Voltage (V) × Current (A)
  • Current (A) = Power (W) ÷ Voltage (V)

Safety Margin

It's recommended to add a 20-30% safety margin to handle power spikes and ensure long-term reliability.

Power Supply Tips

  • Never operate a power supply at more than 80% of its rated capacity for extended periods
  • Ensure proper cooling and ventilation
  • Consider future expansion when sizing your power supply
