To check the wattage of your power supply, you can either use a wattage calculator or physically inspect the power supply itself. A wattage calculator is a software tool that estimates the power consumption of your computer components and recommends a power supply wattage that can handle the load. To use a wattage calculator, you will need to input the wattage of each component in your computer, including the motherboard, CPU, graphics card, RAM, storage devices, and any other peripherals that draw power from the power supply. Once you have entered all of the required information, the wattage calculator will provide you with an estimate of the total power consumption of your computer and recommend a power supply wattage that is sufficient to meet your needs.
If you prefer to physically inspect the power supply, you can look for a label on the side of the unit that indicates the wattage. The wattage will typically be listed in watts (W) or kilowatts (kW). For example, a power supply with a wattage of 500W can provide up to 500 watts of power to your computer components.
