Power Supply Calculation Formula:
From: | To: |
The power supply calculation helps determine the appropriate wattage for a Cooler Master power supply unit (PSU) based on your system's component power requirements plus a safety margin.
The calculator uses the simple formula:
Where:
Explanation: The calculation ensures your PSU can handle peak loads and provides room for expansion.
Details: Choosing the right PSU wattage is crucial for system stability, efficiency, and longevity. Undersized PSUs can cause crashes, while oversized ones waste energy.
Tips: Enter the total power consumption of your components in watts, then add a margin (typically 20-30% of component power). All values must be positive numbers.
Q1: How do I determine component power?
A: Check manufacturer specifications for each component (CPU, GPU, etc.) or use online power calculators.
Q2: What margin should I use?
A: Typically 20-30% of total component power for headroom and efficiency.
Q3: Does Cooler Master recommend specific margins?
A: Cooler Master generally recommends adding at least 20% to your component total.
Q4: What about 80 Plus certification?
A: This calculator gives raw wattage needs. Choose a PSU with appropriate 80 Plus rating for efficiency.
Q5: Should I consider peak power vs continuous power?
A: The calculator gives continuous power needs. For systems with high peak loads, add extra margin.
