Tech Support Forum - View Single Post - Testing Your Power Supply With a Multimeter

**TheMatt** · 09-22-2007, 04:28 PM

I know I have the Laptop article going on, but that has currently stalled while I wait for a book to come in from the public library. In the mean time, I will be using my brand new multimeter to help write an article to test various aspects of the PSU (and its envoirnment) including:

Testing the AC outlet for proper electrical potential (Voltage)
Testing the power cord for Continuity/Resistance (Ohms)
Testing the +3.3v, +5v, and +12v lines for proper electrical potential (Voltage)
Testing the Power_Good signal for proper range

Before I begin, does anyone else have any suggestions for other topics to include?
