1. What is a Power Consumption Calculator for PC?

Definition: This calculator estimates the energy consumption of a PC based on its power rating and usage time.

Purpose: It helps users understand and estimate electricity usage of their computers for energy cost calculations and environmental impact assessment.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( E \) — Energy consumption (kilowatt-hours)
• \( P \) — Power consumption (watts)
• \( t \) — Time of usage (hours)

Explanation: The formula converts watt-hours to kilowatt-hours by dividing by 1000, which is the standard unit for electricity billing.

3. Importance of Power Consumption Calculation

Details: Understanding PC power usage helps in estimating electricity costs, sizing UPS/battery backups, and making energy-efficient choices.

4. Using the Calculator

Tips: Enter the PC's power consumption in watts (check power supply rating or use measuring tools) and the duration of use in hours.

5. Frequently Asked Questions (FAQ)

Q1: How do I find my PC's power consumption?
A: Check your power supply wattage (typically 300-800W for desktops), or use a watt meter for actual measurement.

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

Q3: What's the average power consumption for a PC?
A: Gaming PCs may use 300-500W under load, office PCs 100-200W, and laptops 30-100W.

Q4: How accurate is this calculation?
A: It provides an estimate. Actual consumption varies based on workload, efficiency, and components.

Q5: Can I calculate monthly electricity costs with this?
A: Yes, multiply the result by your electricity rate and number of usage days.
