Where the wattage number comes from
The most accurate source is a wall power meter reading your PC's actual draw. Without one, use our PSU Wattage Calculator to estimate total system draw from your components' rated wattage, and use that as a rough stand-in — real usage under load is usually somewhat lower than the sum of rated maximums.
Frequently Asked Questions
Where do I find my local electricity rate?
Check a recent electricity bill for your price per kWh (kilowatt-hour), or look up your utility provider's published residential rate — rates vary significantly by country and region.
Why might my actual usage be lower than the estimate?
The calculator uses the wattage you enter as a constant draw, but real PCs use less than their maximum rated wattage during lighter workloads like menus or older games — treat the result as an upper-bound estimate.
