Testing my PSU

post #1 of 8
Thread Starter 
Hi,

I'm just after some info, from my thread here you can see I might need to test my PSU, I'm unsure If I use just a molex connector to do this and if it matters that I've got an autoranging multimeter to test with.

I've found a couple of guides, but still a bit in the dark. Thanks

a multimeter is a great tool to use if you are familiar with the fundamentals of electricity. If you are the least bit unsure on how to test, I suggest purchasing a power supply tester. It is quick, easy, and a bit more safe.

just plug it in the PSU pins and it will tell you immediately if there is a problem. I have this very same unit and it works great. A must have tool for any geek working on a computer.

That tester looks ok, but I'd have to look for a retailer in AUS that sells it, but anyway I only just bought this multimeter so I'd rather give that a try.

Fundamentals of multimeters:

1.) Red to hot
2.) Black to ground
3.) Start at the highest setting and work your way down
4.) Don't stand in a pool of water while using it to measure a high voltage source in case you drop the ground lead and kill yourself
5.) Don't try to eat it (it tastes terrible)

lol thanks phaedrus, very wise words

When you say start at highest setting, what do you mean?

Ok I've done some testing...

I used a molex connector. Only ran these tests for about 5 min because the multimeter would beep twice and turn off for some reason.

12v rail on load with prime95 was 12.05v (occasionally 12.06v), on load with Furmark was 12.04v (occasionally 12.03v).

5v rail on load with prime95 was 5.02v, on load with Furmark was 5.02v.

Does this all look ok? Im pretty sure I had everything set up correctly.

Also I don't know why, but my OC reset itself during this.

That's excellent voltage regulation.

hmm ok, thanks Phaedrus. I've had that PSU for about 3 years, bit more than 1 year of running overclocked, do you think a PSU should have performed that well?
