Corsair PSU Calculation Method:
From: | To: |
The Corsair PSU calculation method estimates power supply requirements by summing component power consumption and adding a 20-30% safety margin. This accounts for power spikes, future upgrades, and PSU efficiency over time.
The calculator uses the following formula:
Where:
Explanation: The safety margin accounts for power spikes, capacitor aging, and future upgrades.
Details: An appropriately sized PSU ensures system stability, allows for future upgrades, operates efficiently, and lasts longer by not being constantly stressed.
Tips: Enter your CPU's TDP (from manufacturer specs), GPU power consumption (from manufacturer), number of RAM sticks, drives, and fans. Choose safety margin based on system use (30% for high-end systems).
Q1: Why add a safety margin?
A: To account for power spikes (especially from GPUs), capacitor aging over time, and potential future upgrades.
Q2: What if my components exceed the calculator's estimate?
A: Use the higher safety margin (30%) or manually add 10-20% to the recommended wattage for high-end systems.
Q3: Does this account for overclocking?
A: No. If overclocking, add 20-30% to your CPU and GPU power values before calculating.
Q4: Are there components not accounted for?
A: RGB lighting (add 5W per strip), water cooling pumps (add 20-30W), and PCIe add-on cards may need additional power.
Q5: Should I get the exact calculated wattage?
A: No, always round up to the nearest standard PSU wattage (550W, 650W, 750W, etc.) for better efficiency and longevity.
