1. What is PC Power Consumption?

The PC Power Consumption Calculator estimates the energy usage of a computer system by summing the power draw of individual components over time. This helps users understand their electricity costs and environmental impact.

2. How Does the Calculator Work?

The calculator uses the power consumption formula:

\[ kWh = \frac{(\Sigma P_{components} \times h)}{1000} \]

Where:

$ kWh $ — Kilowatt-hours (energy consumption)
$ P_{components} $ — Power draw of each component (watts)
$ h $ — Usage time in hours
1000 — Conversion factor from watts to kilowatts

Explanation: The equation sums all component power draws, multiplies by usage time, and converts to kilowatt-hours.

3. Importance of Power Calculation

Details: Understanding PC power consumption helps with energy cost estimation, sizing power supplies, and reducing environmental impact through energy efficiency.

4. Using the Calculator

Tips: Enter power values for each component in watts and usage time in hours. Typical values: CPU (65-150W), GPU (75-350W), RAM (2-5W per stick), Storage (5-10W per drive).

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculator?
A: Accuracy depends on input values. For best results, use actual power measurements from monitoring software or hardware.

Q2: Does this include monitor power?
A: No, this calculates only the PC's power. Add monitor power separately if needed.

Q3: How can I reduce my PC's power consumption?
A: Use power-saving modes, upgrade to efficient components, and turn off when not in use.

Q4: What's the difference between watts and watt-hours?
A: Watts measure power (rate of energy use), watt-hours measure energy (power × time).

Q5: How does this translate to electricity cost?
A: Multiply kWh by your electricity rate (e.g., $0.12/kWh × 10kWh = $1.20).
