Analyzing CPU Power Circuit - Testing MOSFET on Board

In this video, we will show you how to test and troubleshoot MOSFETs of PWM block of CPU power on boards. PWM block of CPU power is usually made of several phase and there are more MOSFETs on this block than any other block. And it’s a bit difficult to remove these types of MOSFETs from circuits for testing.
In the video below, you will see how to test them on boards so that if you encounter suspicious MOSFETs, you’ll be able to remove them from boards to perform a final test.

Hello, by accident during testing, 12V on the CPU connector from external PSU is connected in reverse polarity. CPU has not been burned, but there is a click in main PSU when trying to start computer. Which component is most likely damaged, one of these Mosfets?
