1. What is PC Power Usage Estimation?

The PC Power Usage Estimator calculates the energy consumption of a computer system in kilowatt-hours (kWh) based on the power draw of its components and usage duration. This helps estimate electricity costs and environmental impact.

2. How Does the Calculator Work?

The calculator uses the power consumption formula:

Where:

• \( \Sigma P_{components} \) — Sum of all component power draws (CPU, GPU, RAM, etc.)
• \( h \) — Usage time in hours
• 1000 — Conversion factor from watts to kilowatts

Explanation: The equation sums the power consumption of all components, multiplies by usage time, and converts to kilowatt-hours.

3. Importance of Power Estimation

Details: Understanding your PC's power consumption helps with energy cost planning, sizing power supplies, and reducing environmental footprint.

4. Using the Calculator

Tips: Enter power draw for each component in watts (check manufacturer specs), and usage time in hours. Typical values: CPU 65-150W, GPU 75-350W, RAM 2-5W per stick, SSD 2-5W, HDD 6-10W.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this estimate?
A: It provides a rough estimate. Actual consumption varies with workload, efficiency, and power management settings.

Q2: Where can I find my components' power draw?
A: Check manufacturer specifications (TDP for CPU/GPU), or use hardware monitoring tools under load.

Q3: Does this include monitor power?
A: No, this calculates only the PC's power. Add monitor power separately (typically 20-100W).

Q4: How can I reduce my PC's power usage?
A: Use power-saving features, undervolt components, choose efficient hardware, and turn off when not in use.

Q5: How do I convert kWh to cost?
A: Multiply kWh by your electricity rate (e.g., 0.15 $/kWh × 10 kWh = $1.50).
