A power supply unit (PSU) is a device in a computer that converts the alternating current (AC) from the wall outlet to the direct current (DC) needed by the computer’s components.

Here are some points to help you identify the PSU in your PC:

– Check the label on the PSU: Most PSUs have a label on the side or the bottom that provides information about the unit’s wattage, voltage, and amperage. You can use this information to identify the PSU in your PC.
– Check the PC manufacturer’s website: If you bought your PC from a major manufacturer (like Dell or HP), you may be able to find information about the PSU on the manufacturer’s website. Look for the specifications of your specific PC model.
– Check your PC’s manual: If you still have the manual that came with your PC, it may provide information about the PSU. Look for a section about hardware specifications or system components.
