Computer Power Supply Repair & Troubleshooting Guide

A computer power supply (PSU) is the heart of every desktop system. Without a stable and reliable PSU, your computer cannot run properly. Many users face problems such as sudden shutdowns, failure to boot, unstable voltage, or complete power failure. In most cases, these issues can be traced back to the switching power supply frequency circuit, which controls how the PSU manages energy conversion.

In this detailed video guide, we cover:

• ✅ How a computer power supply works (overview of internal circuits)
