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.
