A PC power supply checker is a critical diagnostic tool designed to verify if your power supply unit (PSU) is providing the correct voltages to your computer's components. Whether you are troubleshooting random restarts or a PC that simply won't turn on, these devices provide immediate feedback without the need for a functioning motherboard. Why You Need a Dedicated PSU Tester
It is vital to understand what a power supply checker cannot do. A PSU tester simulates a small load, but it does not simulate the heavy load of a high-end graphics card or a power-hungry CPU.
Many testers have side ports for the CPU (4/8-pin) and GPU (6/8-pin) cables. Plug these in one at a time to ensure those specific lines are delivering the correct voltage.
Plug the PSU into the wall outlet and flip the switch on the back of the PSU to the "On" (I) position. The PSU should instantly power up, and the tester screen should illuminate.
