In many cases, that's not the actual power. Many assumptions and predictions has to be made to give you a rough estimate of the total system power. However TDP is only a specification of how much power the cooling system should dissipate for the component to stay within the thermal limits in extreme conditions. The calculator estimates both the idle and full load power consumptions and recommends a PSU wattage rating for the selected components.Ī typical PSU calculator works by calculating the power requirements from the Thermal Design Power (TDP) values from some main parts on the system. It can also be used to calculate the cost of electricity as well as optimize the parts for energy efficiency or low noise levels. It can be used to select a proper power supply unit for your system. It's a must tool for estimating the power consumption of a modern desktop PC. PowerSuppl圜 offers you the most accurate PC power consumption calculator on the web for free.
