12v rail concern

cTurtle98

my computer has a 550w PSU

 

Heres my Specs:

CPUID HW Monitor is saying my +12 is at 6.7v

but my BIOS says its at 12v when I boot into it

 

should I be concerned?

 

this power supply calculator website says that my load wattage with what i told it I have would be 520 watts

could I be overloading my PSU?

 

I have been getting a bunch of random BSODs lately, could it be the PSU

 

how do I measure to tell if my psu is overloaded?

 

any help is appreciated

PSUs don't cause crashes. The instability is elsewhere. Most likely the CPU overclock.

The PSU has under voltage protection, and would shut down if the voltages were too low. If the PSU were is overloaded, it has OPP, which again, would shut it down.

You are not going to be using anywhere near 520W either. More like 250W.

PSU´s absolutely do cause crashes, if you overload them the voltage drops and the computer stops working as it should.

 

i would double check with a multimeter that the 12V is actually not at 12V but 6V seems very unrealistic as the PC would not be functional with this voltage.

The system shutting down is not the same as crashing. If the voltage drops too much on a PSU that isn't absolute crap, the UVP will shut it down.

define what you mean with crashing, what OP describes with BSOD is a classic example for unstable voltage that causes certain devices to malfunction.

BSOD is usually CPU/RAM related, typically just an unstable overclock.

LOL!  If your +12V was 6.7V, your system wouldn't even be running.

 

If we were to look at the software, we would have to ask ourselves, "where is it getting that 6.7V reading from?"

 

Obviously not the PSU, but where?  That may be the root of your problem.

 

Best advice I can give you is make sure all your power connectors are secure on the motherboard.  But odds are it's a RAM issue.
