The power supply unit consists of some regular electric components like a transformer to increase or reduce voltage level, a rectifier that converts AC into DC voltage, voltage regulators to control the output voltage as needed. By benchmarking your GPU, you can get an idea of how smoothly your system will run and compare your results to computers with similar configurations in order to ensure things are working as intended. Test your results A properly executed PSU test using a multimeter should confirm that the power supply is in good working order or if it should be replaced. How to Test a Computer Power Supply. If any pin gives more or less than the acceptable values (maximum 4% tolerance), we can identify that pin and fix them from any professionals.eval(ez_write_tag([[300,250],'techdim_com-box-4','ezslot_7',113,'0','0'])); PSU failure can cause a lot of problems. Damaged pins can supply excess voltages to the components that can cause the components to damage or even burn out. If you have a negative polarity power supply, then you will get a negative reading. Your computer’s power supply is the single most important component in the case. The black connectors work as a ground unit. Please note, however, that the former – the multimeter test – should only be performed very carefully and usually only when you have previous experience with electrical devices and tests. Before doing these operations, we should ground ourselves to prevent any unwanted electrical surges that can damage the components. By benchmarking your GPU, you can get an idea of how smoothly your system will run and compare your results to computers with similar configurations in order to ensure things are working as intended.
