1. What is PC Power Consumption Calculator?

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 management and cost calculation.

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 systems, and making energy-efficient choices.

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. Typical PCs range from 50W (idle) to 500W (gaming).

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

Q3: How accurate is this calculation?
A: It provides an estimate. Actual consumption varies based on workload, efficiency, and components.

Q4: Can I calculate monthly electricity cost with this?
A: Yes, multiply the result by your electricity rate and number of usage days.

Q5: What's a typical gaming PC consumption?
A: Gaming PCs typically consume 300-800 watts under load, depending on components.
