DIY: How to Test PSU with Multimeter + Tips

Determining the operational status of a power supply unit (PSU) using a multimeter is a valuable skill for troubleshooting computer hardware issues. The process involves measuring the voltage outputs of the PSU’s various connectors to ascertain whether they fall within acceptable tolerance levels. For instance, the 12V rail should ideally read between 11.4V and 12.6V under load to be considered healthy.

Verifying a PSU’s functionality prior to replacing other components can save considerable time and expense. Historically, faulty power supplies have been a common cause of seemingly unrelated computer malfunctions, highlighting the importance of this testing method. Early identification of a failing PSU prevents potential damage to sensitive electronic components connected to it.
