1. What is PC Power Consumption?

PC 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 assessing environmental impact.

2. How Does the Calculator Work?

The calculator uses the energy consumption formula:

\[ kWh = \frac{(\Sigma P_{components} \times h)}{1000} \]

Where:

$ \Sigma P_{components} $ — Sum of all component power draws (CPU, GPU, RAM, etc.)
$ h $ — Usage time in hours
1000 — Conversion factor from watts to kilowatts

Explanation: The formula calculates energy consumption by multiplying total power by time and converting to kilowatt-hours (kWh), the standard unit for electricity billing.

3. Importance of Power Calculation

Details: Understanding your PC's power consumption helps with:

Estimating electricity costs
Selecting an appropriate power supply
Assessing environmental impact
Planning for backup power solutions

4. Using the Calculator

Tips:

Enter power values in watts (W) for each component
Include all major components (CPU, GPU, RAM, storage)
Add additional components in the "Other" field
Enter usage time in hours (can be decimal, e.g., 1.5 for 90 minutes)
Typical values: CPU (65-150W), GPU (75-350W), RAM (2-5W per stick), SSD (2-5W)

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 based on workload and efficiency.

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

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

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 does my electricity bill show more consumption?
A: This calculator only estimates PC usage. Other appliances and devices contribute to your total bill.
