1. What is the Outervision Power Supply Calculator?

The Outervision Power Supply Calculator helps determine the appropriate wattage for your computer's power supply unit (PSU) based on your system's components and a safety factor to ensure stable operation.

2. How Does the Calculator Work?

The calculator uses the following methodology:

Where:

• \( P_{components} \) — Power consumption of individual components (CPU, GPU, RAM, etc.)
• 1.2-1.3 — Safety factor to account for power spikes and future upgrades

Explanation: The safety factor ensures your PSU isn't running at 100% capacity, which improves efficiency and longevity.

3. Importance of Proper Power Supply Sizing

Details: An undersized PSU can cause system instability, crashes, or even component damage. Oversizing wastes money and reduces efficiency at low loads.

4. Using the Calculator

Tips: Enter power consumption for each component in watts. Use manufacturer specifications when available. Select 1.3 safety factor for high-end systems or planned upgrades.

5. Frequently Asked Questions (FAQ)

Q1: Where can I find component power consumption?
A: Check manufacturer specifications (TDP for CPUs/GPUs), reviews with power measurements, or use online databases.

Q2: Should I add extra wattage for overclocking?
A: Yes, add 20-30% extra to the component's base power if you plan to overclock.

Q3: What about efficiency ratings (80 Plus)?
A: Efficiency affects power draw from the wall but not the power delivered to components. This calculator gives the required PSU output.

Q4: How accurate is this calculator?
A: It provides a good estimate, but real-world power draw varies with workload. Professional reviews provide precise measurements.

Q5: Should I round up to available PSU wattages?
A: Yes, choose the next standard wattage above your calculated value (e.g., 550W → 600W PSU).
