Check: whether the power cord and socket are electric, whether the motherboard power plug is connected, whether the UPS is normally powered, and then confirm whether the power supply is faulty, the simplest is the replacement method, but it is impossible for the general user to have spare parts such as power supply at home, at this time you can try to use the following method (note: be cautious):

First connect the hard disk, CPU fan, or CDROM, and then connect the ATX motherboard power plug to two pins with a wire (protrude one side of the plug to yourself, the upper pin from the left 4th and the lower pin from the right 3rd, the direction must be correct), and then turn on the ATX power switch, if the power supply fan rotates, the power supply is normal, otherwise the power supply is damaged.

If the power supply is fine, simply short the jumper of the power switch on the motherboard, and if it is normal, the power switch on the chassis panel is damaged.
