Rated power refers to the maximum load of a power supply under stable and continuous operation. Rated power represents the true load capacity of a power supply. For example, the rated power of a power supply is 300W, which means that when working continuously for 24 hours a day and 365 days a year, the sum of all loads cannot exceed 300W. However, in reality, power supplies have a certain degree of redundancy. For example, a power supply with a rated power of 300W can work stably and normally at 310W, but try not to use it beyond the rated power, otherwise it may cause the power supply or other computer components to burn out due to overcurrent.
