1. What is Computer Power Consumption?

Computer power consumption refers to the amount of electrical energy a computer system uses during operation. It's important for estimating electricity costs, sizing power supplies, and understanding environmental impact.

2. How Does the Calculator Work?

The calculator uses the power consumption formula:

Where:

• \( kWh \) — Kilowatt-hours (energy usage)
• \( \Sigma P_{components} \) — Sum of all component power consumption in watts
• \( h \) — Usage time in hours

Explanation: The equation calculates total energy usage by multiplying total power by time and converting to kilowatt-hours.

3. Importance of Power Calculation

Details: Understanding your computer's power consumption helps in selecting appropriate power supplies, estimating electricity costs, and making energy-efficient choices.

4. Using the Calculator

Tips: Enter power consumption for each component in watts and your daily usage time in hours. Typical values:

• CPU: 65W-125W (gaming), 35W-65W (office)
• GPU: 75W-350W
• RAM: 2W-5W per stick
• Storage: 5W-10W per drive

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculator?
A: It provides estimates based on component specifications. Actual usage varies with workload and efficiency.

Q2: Where can I find my components' power consumption?
A: Check manufacturer specifications or use hardware monitoring tools like HWMonitor.

Q3: Does this include monitor power?
A: No, this calculates only the computer's power. Add monitor power separately if needed.

Q4: How can I reduce my computer's power consumption?
A: Use power-saving features, upgrade to efficient components, and turn off when not in use.

Q5: How does this translate to electricity cost?
A: Multiply kWh by your electricity rate (e.g., $0.12/kWh × 1.5kWh = $0.18 per day).
