1. What is a Power Usage Calculator for PC?

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

Purpose: It helps users understand their PC's electricity consumption for energy cost estimation 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)
• \( t \) — Usage time (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 Usage Calculation

Details: Understanding PC power consumption helps with energy cost budgeting, comparing system efficiency, and reducing carbon footprint.

4. Using the Calculator

Tips: Enter the PC's power consumption in watts (check PSU rating or use monitoring software) and the usage time in hours. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I find my PC's power consumption?
A: Check your power supply unit (PSU) rating, use a wattage meter, or estimate based on components (CPU/GPU TDP).

Q2: Is this the actual energy cost?
A: No, this calculates kWh usage. Multiply by your electricity rate ($/kWh) to estimate cost.

Q3: Does this include monitor and peripherals?
A: No, this calculates only the PC's consumption. Add monitor/peripherals separately for total setup usage.

Q4: What's a typical gaming PC consumption?
A: Gaming PCs typically range from 300-800 watts under load, while idle might be 50-150 watts.

Q5: How accurate is this calculation?
A: It provides theoretical maximum. Actual usage varies based on workload, efficiency, and power management settings.
