-5V?

 

Why do you expect to get any -5V at all?

What is supposed to give you -5V? Your power supply? Why? ;)

Take a look at your power supply's label or specifications. How much power does it provide on -5V?

Hello, i just changed my psu after old one died.I think it might matter so i will tell you how it died.One day i was just trying to turn on my pc and psu started making some wierd sounds, i thought it might be the prop(cooler), but it isn't its some of the electronics.I tested in two programs (speccy and SIW) for the voltages.All Voltages were good but one , -5 volts , which should be -5V it was -13.So after some time it just died and when i turned my pc on again it worked for 3 s and turned off.Also i have tried it by connecting green and black wires on pin and put it in wall and it made the same noise and died.
 

Anyways, i decided to change my psu.I bought cooler master gx650 bronze.And i installed it and it worked.I opened up those programs for spec again and it showed -5V to be -13 again.Im really confused but im also scared if my motherboard or something else might be broken and that's why it died.

Only way to know is to get a multimeter for measurement. board measurements are sometimes wrong.

Ok, so it might be problem with sensor , right?

Because it showed similiar values with old psu.

I think you are fine, something else might have killed your previous PSU

Yeah. -5V was removed from the ATX specification in 2003. :)

 

 

Also, software voltage readings are never accurate anyway. Software can show correct voltages while they're incorrect in reality, and the other way around.

Only with fan noises, but by the fact that the PSU is supposed to have -13 I think it is not a problem

Fans, and they will get noisy when they're about to go, or when they're under load (depends on how noisy the circuit is). If you load a PSU with a constant heavy load it may scream for mercy, or when they're getting old they just die. I lost a Raidmax one because it was getting old, good PSU it just bit the dust finally after 5-6 years, but it squealed and made a pop noise, pulled it apart and the caps had bloated.
