1. What is PC Power Consumption Calculation?

This calculator estimates the electricity consumption of your PC build in kilowatt-hours (kWh), which is the unit used by Meralco for billing. It helps you understand and predict your computer's impact on your electricity bill.

2. How Does the Calculator Work?

The calculator uses the power consumption formula:

Where:

• \( \Sigma P_{components} \) — Sum of all component power draws (CPU, GPU, RAM, etc.)
• \( h \) — Total usage time in hours (daily hours × billing period days)
• 1000 — Conversion factor from watts to kilowatts

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

3. Importance for Meralco Billing

Details: Meralco bills customers per kWh consumed. Understanding your PC's consumption helps manage electricity costs and choose energy-efficient components.

4. Using the Calculator

Tips:

• Find component power ratings from manufacturer specifications
• For accuracy, measure actual power draw with a watt meter if possible
• Adjust the ₱/kWh rate if Meralco's current rate differs from the default ₱10

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculator?
A: It provides estimates based on component TDP (thermal design power). Actual usage may vary based on workload and efficiency.

Q2: Where can I find my components' power ratings?
A: Check product specifications on manufacturer websites or retail listings (look for TDP or power consumption).

Q3: Does this include monitor and peripherals?
A: No, add those to "Other Components" or calculate separately.

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

Q5: What's the average gaming PC consumption?
A: Typically 300-600W under load, but varies greatly by components and usage patterns.
