I've been having issues with my computer lately and thought my motherboard was toast because several ports failed. I recently replaced the motherboard, RAM, and CPU, but now when I plug everything in, nothing happens. I'm not super knowledgeable about this stuff, but I do have a multimeter. I've heard I should test the 24-pin connector, but I'm not exactly sure how to go about it or what readings I should expect from a 650-watt power supply. Any advice on how to test it and what voltages I should be looking for?

Honestly, I recommend keeping a spare power supply around. It's the easiest way to figure out if that's the issue. If you have an old working PC, try using the suspect power supply in it. If it works there, it’s likely okay. Most faulty power supplies just stop working rather than giving out bad voltages.
When I used my multimeter on the 24-pin connector, I was getting pretty low readings too—around five volts. If that's what you're seeing, it could point to a dead or dying power supply, but it could also be your power switch malfunctioning. It's worth double-checking everything!
There's a straightforward guide available which explains how to test your power supply with a multimeter. Just keep in mind that power supplies can behave differently under load, so it might not give you a full picture. Watching videos to see the equipment in action can be really helpful too.
