PC Problems – Power Supply or motherboard?
June 16, 2011
I am looking for help with an annoying PC problem. My PSU test results are: Purple: 5.02v Green: 5.00v** Grey: 5.10v on power on Red: 5.10v on power on Orange: 3.38v on power on* Yellow: 11.74v *This is the anomaly I can see. It is too low. What would this low voltage cause? ** Is Green too high? Orange is 0.07v when no power is connected (?) and 0.19v when off but power connected. I also measured the V on the power switch jumper. This read 0.93v. Is this too low? I measured the current by removing the AC cord, disconnect the power connectors and attaching the meter leads to green and black. After reconnecting the AC cord the reading was 0.14. So motherboard problem or PSU? Any ideas please message me!
