Estimate the power requirements for your PC build with our comprehensive OuterVision PSU Calculator. This tool helps you determine the ideal wattage for your power supply based on individual component power consumption.

OuterVision PSU Calculator

Recommended PSU Wattage:
0 W
Calculated based on component load + buffer.

OuterVision PSU Calculator Formula:

Total Wattage (W) = (CPU + GPU + Others) × (1 + Margin / 100)

Variables:

  • CPU TDP: The Thermal Design Power of your processor, representing maximum power draw at stock speeds.
  • GPU TDP: The power consumption of your Graphics Card, usually the most demanding component.
  • Other Components: Estimation for Motherboard (approx. 30W), RAM (3W per stick), Storage, and Fans.
  • Safety Margin: A 20-30% buffer is recommended to account for capacitor aging and efficiency peaks.

What is OuterVision PSU Calculator?

The OuterVision PSU Calculator is the industry standard for determining how much power your computer needs. Selecting the right Power Supply Unit (PSU) is critical for system stability and longevity. A PSU that is too weak can cause crashes or damage components, while one that is far too powerful is inefficient.

This tool aggregates the power draw (TDP) of individual components and adds a safety buffer, ensuring you choose a PSU that operates within its most efficient range (usually 50-80% load).

How to Calculate PSU Wattage (Example):

  1. Identify your CPU TDP (e.g., Intel i5-12600K = 125W).
  2. Identify your GPU TDP (e.g., NVIDIA RTX 3060 = 170W).
  3. Sum basic components (approx. 60W for standard builds).
  4. Total Base Load = 125 + 170 + 60 = 355W.
  5. Apply 20% Safety Margin: 355W * 1.2 = 426W.
  6. Recommended PSU: 450W or 500W unit.

Frequently Asked Questions (FAQ):

Is a 500W PSU enough for gaming? It depends on the GPU; for mid-range cards like the RTX 3060, yes, but high-end cards require 750W+.

What is 80 Plus rating? It is an efficiency certification. A higher rating (Gold/Platinum) means less power is wasted as heat.

Why add a safety margin? PSU efficiency peaks around 50% load, and capacitors age over time, slightly reducing output capacity.

Does a 1000W PSU always draw 1000W? No, a PSU only draws what the system components demand from the wall.
