  2. Enter Your Component Wattages
    • CPU Watts (W): Enter your processor’s power consumption. Example: 95 W.
    • GPU Watts (W): Enter your graphics card’s power draw. Example: 250 W.
    • Other Components Watts (W): Include RAM, storage, cooling fans, and peripherals. Example: 100 W.
  3. Click Calculate
    Press the “Calculate” button. A progress bar will simulate the calculation, enhancing user experience.
  4. View Your Results
    Once complete, the tool displays:
    • Total Watts: Sum of all entered components.
    • Recommended PSU: Calculated by adding a 25% safety margin and rounding to the nearest 50 W for optimal performance.
  5. Copy or Share Your Results (Optional)
    The tool allows you to copy results to your clipboard or share them via social media directly.

Practical Example

Suppose you have the following components:

  • CPU: 95 W
  • GPU: 250 W
  • Other components: 100 W

Step 1: Enter the values in the calculator.
Step 2: Click Calculate.

The calculator will show:

  • Total Watts: 445 W
  • Recommended PSU: 550 W

This ensures that your power supply can handle your current system while leaving a margin for upgrades or peak loads.
