How To: Test PSU Voltages Posted by Mike @ 9:43 P.M. on 11/02/02

The tool.


The hardcore PC user or overclocker requires a top-notch power supply to keep everything sufficiently powered. Today we'll be showing you all an easy way to test your power supply's voltages. It's the exact same thing that we do whenever we're testing out a power supply. The process is easy and it will give you the true voltages that your power supply is supplying to your components, instead of the readings that your favorite program gives you, which may be incorrect.

Only one tool is required to test your voltages, a multimeter. We currently use a Radio-Shack digital multimeter, which can be found here. Thirty dollars does seem like a lot just to test some voltages, but if you look around the internet I'm sure you'll find a multimeter for much cheaper. Be advised, you will probably want a digital, which will display the voltages on a LCD screen instead of you trying to read what a needle is pointing to. I'd also reccomend a multimeter that has an Auto-Ranging feature. Auto-ranging does just what it sounds like, it automatically selects a range when you are measureing voltages (ie: 1.000V, 10.00V, 100.0V, 1000V).

Before we get started, I'd like to remind everyone who is going to try this to be careful. Electricity isn't something that should be played with, and precautions should be taken to avoid being shocked or electricuted. To be safe, remove any rings or watches from your hands and use a wrist grounding wire.
