1. What is PC Power Consumption?

PC power consumption refers to the amount of electrical energy used by a computer system. It's typically measured in watts (W) for instantaneous power or kilowatt-hours (kWh) for energy consumption over time.

2. How Does the Calculator Work?

The calculator uses the power consumption formula:

Where:

• \( P_{components} \) — Power draw of each component (CPU, GPU, RAM, etc.) in watts
• \( h \) — Usage time in hours
• 1000 — Conversion factor from watts to kilowatts

Explanation: The equation sums the power draw of all components, multiplies by usage time, and converts to kilowatt-hours.

3. Importance of Power Calculation

Details: Understanding your PC's power consumption helps estimate electricity costs, select appropriate power supplies, and make energy-efficient choices.

4. Using the Calculator

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

• CPU: 65W-125W (gaming), 15W-45W (laptop)
• GPU: 75W-350W (gaming), integrated graphics use less
• 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 TDP (thermal design power). Actual usage varies with workload and efficiency.

Q2: Where can I find my components' power draw?
A: Check manufacturer specifications, product documentation, or reputable review sites that measure power consumption.

Q3: Does this include monitor power?
A: No, this calculates only the PC's power. Add monitor power separately (typically 20W-100W).

Q4: How can I reduce my PC's power consumption?
A: Use power-saving features, optimize component selection, enable sleep modes, and reduce unnecessary usage.

Q5: Why calculate in kWh?
A: Electricity bills are calculated in kilowatt-hours, making kWh the most practical unit for cost estimation.
