1. What is PC Power Consumption?

PC power consumption refers to the amount of electrical energy used by all components of 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 following formula:

Where:

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

Explanation: The equation calculates total energy consumption by multiplying total power draw by usage time and converting to kWh.

3. Importance of Power Calculation

Details: Understanding PC 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 usage time in hours. At minimum, CPU and GPU power should be provided.

5. Frequently Asked Questions (FAQ)

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

Q2: Where can I find my components' power draw?
A: Check manufacturer specifications (TDP for CPU/GPU), power supply calculators, or use hardware monitoring tools.

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

Q4: How does idle vs load affect power?
A: Power consumption varies significantly between idle and full load (often 30-70% of TDP at idle).

Q5: Can I calculate my electricity cost from this?
A: Yes, multiply kWh result by your electricity rate (per kWh) to estimate cost.
