1. What is the iCUE Wattage Calculator?

The iCUE Wattage Calculator estimates the recommended power supply unit (PSU) wattage for Corsair iCUE-configured systems. It accounts for all major components and adds a safety margin to ensure stable operation.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( P_{components} \) — Sum of all component wattages (CPU, GPU, RAM, etc.)
• \( 1.2 \) — Standard 20% safety margin
• \( 1.3 \) — 30% margin for high-performance systems

Explanation: The safety margin accounts for power spikes, future upgrades, and ensures the PSU operates in its most efficient range.

3. Importance of Proper PSU Sizing

Details: An appropriately sized PSU ensures system stability, improves energy efficiency, and provides headroom for future upgrades. Undersized PSUs can cause crashes and reduce component lifespan.

4. Using the Calculator

Tips: Enter wattage for all major components. Use manufacturer specifications for accurate values. Select 20% margin for standard builds, 30% for high-performance or overclocked systems.

5. Frequently Asked Questions (FAQ)

Q1: Why include a safety margin?
A: PSUs operate most efficiently at 50-80% load. The margin accounts for power spikes and future upgrades.

Q2: How do I find my component wattages?
A: Check manufacturer specs or use tools like Corsair's PSU Finder. GPU and CPU wattage are most critical.

Q3: Does this account for iCUE lighting?
A: Yes, the calculator includes headroom for RGB lighting and iCUE-controlled components.

Q4: Should I round up to available PSU wattages?
A: Yes, choose the next available standard PSU wattage above the calculated value.

Q5: Does this work for non-Corsair systems?
A: Yes, the calculation method is universal, though optimized for iCUE configurations.
