The poor PSU might get almost zero press time and none of the glory that flashier components like GPUs and advanced multi-core CPUs get, but the humble PSU is the bedrock of a stable PC build.
Experiencing computer problems? They could be caused by a failing (or outright fried) power supply unit (or an underpowered one for newer hardware devices you have added). Here are some signs your PC’s PSU hardware is the problem—and three ways to test the PSU to see if it’s still working properly.
The power supply unit is often overlooked in the PC troubleshooting process. But if you have unstable power, you’ll have numerous small and difficult-to-diagnose problems cropping up all over the place.
Testing your computer’s power supply unit is fairly simple. You can test the PSU with a basic jumper test, multimeter, or power supply tester. This will help you rule out power delivery issues as the source of your problem.
