OK I've got a desktop that starts but won't boot(different issue) in my troubleshooting I decided to start up my power supply with a paper clip and test the voltages.
The power supply is an apevia iceberg 680w. It's at least four years old, and I have replaced two fans and added another fan to the power supply, after which it worked for two years.
Molex: Yellow wire: 12.01v, Red wire: 5.20
PCI-e expansion 6-pins: yellow wires: 12.01v
4/8pin CPU: yellow wires 12.01.v
I'm told the yellow wire voltages should read 12.35v-12.4v which means that my numbers are low by an amount that I would think is considerable. I'm told the red wire voltages should be "around" 5v, I would assume 5.0v-5.05v meaning my voltages for red are considerably high.
Orange: 3.41 Red: 5.20 Yellow: 12.01 purple: 5.06 grey: 5.20 blue: 11.53 green: could not get a reliable number
Orange: 3.41 Red: 5.05 Yellow: 12.35 purple: 5.07 grey: 5.09 blue: 11.34 green: 0.06
I tried four different black(groud) wires with the green, one gave me a number that kept rising, two gave me no reading, and a fourth gave me a beeping noise from my multimeter after a couple seconds.
As you can see, my orange, and purple are close.
My red, yellow, grey and blue are not.
I think the green is pretty important, and I'm pretty sure that the readings I received were not good.
I would assume that my results are bad, but I'm not sure about the tolerance on these values. Can anyone confirm my suspicions that this psu is faulty?
