Power Supply Planning

Calculating Power Requirements

Basic Formula

Total Watts = (LED Length in Meters × Watts per Meter) × 1.2 (Safety Factor)

For addressable LEDs like WS2812B, use our WS2812B power calculator to get exact amp and watt requirements based on your LED count.

Common Power Requirements

• Standard Density: 4.8W per meter (30 LEDs/meter)
• High Density: 9.6W per meter (60 LEDs/meter)
• Ultra High Density: 14.4W per meter (120 LEDs/meter)

Example Calculation

Project: 5 meters of standard density RGB strip
Power Needed: 5m × 4.8W/m × 1.2 = 28.8W
Recommended Power Supply: 30W 12V DC

Choosing Power Supply

Voltage Matching

• 5V Strips: Use 5V power supply
• 12V Strips: Use 12V power supply
• 24V Strips: Use 24V power supply (less voltage drop)

Amperage Capacity

• Calculate Total Current: Total watts ÷ voltage
• Add 20% Safety Margin: Prevent overloading
• Consider Future Expansion: Plan for additional strips

Power Supply Types

• Desktop Power Supplies: For indoor installations
• Waterproof Power Supplies: For outdoor use
• Mean Well Brands: Professional reliability
• Switching Power Supplies: Efficient and compact
