1. What is the Outervision Power Calculation?

The Outervision methodology calculates total PC power consumption by summing individual component power draws and applying a safety margin (typically 20-30%). This ensures your power supply unit (PSU) can handle peak loads and maintains efficiency.

2. How Does the Calculator Work?

The calculator uses the Outervision formula:

Where:

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

Explanation: The safety margin accounts for power spikes, aging components, and maintains PSU efficiency (typically best at 50-80% load).

3. Importance of Proper PSU Sizing

Details: An appropriately sized PSU ensures system stability, prevents shutdowns under load, improves energy efficiency, and extends component lifespan.

4. Using the Calculator

Tips:

• Check manufacturer specs for component TDP (Thermal Design Power)
• Include all major components (CPU, GPU, drives, cooling)
• Use 30% margin for gaming PCs or overclocked systems
• Round up to nearest standard PSU wattage (550W, 650W, etc.)

5. Frequently Asked Questions (FAQ)

Q1: Should I get exactly the calculated wattage?
A: No, round up to the nearest standard PSU size (e.g., if you calculate 480W, get a 550W or 600W unit).

Q2: What about PSU efficiency ratings?
A: 80 PLUS ratings (Bronze, Gold, etc.) indicate efficiency but don't affect wattage calculation. Higher ratings save energy and reduce heat.

Q3: How do I find my components' power draw?
A: Check manufacturer specifications (TDP for CPU/GPU), or use hardware monitoring tools under load.

Q4: Does RGB lighting add significant power?
A: Typically no (5-15W total), but include it in "Other Components" for completeness.

Q5: Should I account for future upgrades?
A: Yes, add 10-20% extra wattage if planning significant upgrades (better GPU, more drives, etc.).
