Step 3: Enter RAM Amount (GB)

Type the total amount of system memory (RAM) in gigabytes—for example, 16 GB or 32 GB.

Step 4: Enter Number of Storage Drives

Add how many drives (SSD or HDD) you’ll be using. Each drive contributes slightly to overall power usage.

Step 5: Select Usage Type

Choose how the PC will be used:

• Basic / Office for everyday tasks
• Gaming for entertainment builds
• Rendering / Video Editing for creative professionals
• Workstation / Server for heavy computational workloads

Step 6: Click “Calculate”

Once you hit the Calculate button, a brief progress bar will appear. After about 3 seconds, your results will display automatically, and the page will scroll smoothly to the output section.

Step 7: View Your Results

You’ll see detailed output including:

• Estimated Power Usage (W)
• Recommended PSU Wattage (W)
• Performance Score
• Overall Rating (Basic, Mid-Range, High-End, or Enthusiast/Pro)

Step 8: Copy or Share Results

You can easily copy the results to your clipboard or share your build score directly on social media with built-in Copy and Share buttons.

💡 Example: Gaming PC Build

Let’s take a practical example.

Inputs:

• CPU: Intel i7 / Ryzen 7
• GPU: RTX 4070 / RX 7800
• RAM: 16 GB
• Storage Drives: 2
• Usage Type: Gaming

Results:

• Estimated Power Usage: ~450 W
• Recommended PSU Wattage: ~560 W
• Performance Score: ~720
• Rating: High-End

This means your gaming build is powerful enough for 1440p or even 4K gaming, and a 600W or higher PSU would be ideal.
