1. What is a PC Power Consumption Calculator?

Definition: This calculator estimates the energy consumption of a PC in kilowatt-hours (kWh) based on its power draw and usage time.

Purpose: It helps users understand and estimate electricity costs for their computers and plan energy usage.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ E_{kWh} = \frac{P_w \times t}{1000} \]

Where:

$ E_{kWh} $ — Energy consumption (kilowatt-hours)
$ P_w $ — Power consumption (watts)
$ t $ — Usage time (hours)

Explanation: The power consumption in watts is multiplied by usage time in hours, then divided by 1000 to convert to kilowatt-hours.

3. Importance of Power Consumption Calculation

Details: Understanding PC energy usage helps with electricity cost estimation, energy efficiency planning, and environmental impact assessment.

4. Using the Calculator

Tips: Enter the PC's power consumption in watts and the usage time in hours. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I find my PC's power consumption?
A: Use a power meter, check your PSU rating, or use manufacturer specifications. Gaming PCs typically range 300-800W under load.

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

Q3: How can I estimate my electricity cost from this?
A: Multiply the kWh result by your local electricity rate (typically $0.10-$0.30 per kWh).

Q4: Is this for peak or average power consumption?
A: For accurate results, use average power consumption over the usage period.

Q5: What's a typical power consumption for a laptop?
A: Most laptops consume 30-90 watts under normal use.
