  • Real-time progress bar to indicate calculation status.
  • Total power draw and recommended PSU output displayed clearly.
  • Copy and share options for your results.
  • Mobile-friendly design for use on any device.

Step-by-Step Guide: How to Use the PC Power Draw Calculator

Follow these steps to calculate your PC’s power draw:

  1. Open the PC Power Draw Calculator on your preferred browser.
  2. Enter your CPU wattage in the CPU Wattage field (e.g., 95W).
  3. Input GPU wattage in the GPU Wattage field (e.g., 250W).
  4. Add RAM wattage in the RAM Wattage field (e.g., 10W).
  5. Provide storage wattage in the Storage Wattage field (e.g., 10W).
  6. Include other components (cooling fans, peripherals, etc.) in the Other Components field (e.g., 30W).
  7. Click “Calculate” to start the calculation process. A progress bar will appear showing the calculation status.
  8. View the results: Once complete, the calculator displays:
    • Total Power Draw (sum of all components)
    • Recommended PSU wattage based on safe headroom
  9. Copy or share your results using the provided buttons for easy reference.

Practical Example

Let’s say you have the following PC components:

  • CPU: 95W
  • GPU: 250W
  • RAM: 10W
  • Storage: 10W
  • Other Components: 30W

Step 1: Input these values into the respective fields.
Step 2: Click Calculate.
Step 3: The calculator shows:

  • Total Power Draw: 395W
  • Recommended PSU: 500W

This ensures you have a PSU with enough headroom for safety and future upgrades.


Additional Tips for Using the Calculator

  • Include all peripherals: Fans, RGB lighting, and external drives consume power too.
  • Check manufacturer specs: Verify each component’s TDP or power consumption for accuracy.
  • Allow buffer: Always choose a PSU slightly higher than the total calculated wattage.
  • Regular updates: Recalculate if you upgrade components like GPU or CPU.
  • Monitor system usage: Use software tools to track real-time power consumption for optimization.

Use Cases for the PC Power Draw Calculator

  • Building a new gaming PC: Ensure your PSU can handle high-end GPUs and CPUs.
  • Upgrading your PC: Determine if your current PSU supports new components.
  • Overclocking setups: Calculate additional wattage required for stability.
  • Energy-conscious users: Monitor and reduce power consumption.
  • IT professionals: Quickly recommend PSU size for client builds.
