10 Best Power Supply Tester 2021 – Reviews & Guide

The power supply is the foundation of a modern PC – without one, you won’t be able to run anything. From the CPU to the RAM, GPUs, and even other peripherals, every component needs power from your PSU.

More than that, though, it has the job of providing clean power. To do this, a top-quality power supply has to employ a solid build quality (well-shielded wires are a must) and use quality components (namely capacitors and transformers).
