Is this correct guys? I know that 12v runs my graphic card's, BluRay, fans, etc. But why is it saying 0v?? Everything is running fine in my PC, no problems (as of yet..)?

Does it say +12V when you use your multimeter on the yellow wires and a good ground?

Get a DMM and check voltage between a black wire and yellow wire on your 24-pin MB connection, well really any yellow wire should read 12v iirc. yellow=12v, black=ground, red=5v, that's going off of memory..you won't get more accurate than using a multimeter that's for damn sure. Maybe update your MB drivers, enable ACPI in bios, ACPI 2.0 if ya got it, hell maybe update your bios too. Different programs will read differently for temps and voltages more often than not in my experiences. But in reality if your 12v was reading 0v, your PC wouldn't be able to run right now.

That just means the program isn't reading it properly. If 12V was really @ 0 it would not power on.

Your voltage meter hasn't accurate, if your real 12V are 0, your PC cannot start.

but since your PC are running correctly, you don't have any problem with your PSU.

As others have mentioned, OCCT and Everest can provide more accurate readings.

The best and the most accurate voltage reader are Multimeter like this:



that's never fail unless the unit itself are broken.

They are actually very easy to use. You just connect it to the positive and a negative wire and it reads the voltage.

voltage reading programs arent just innacurate as this thread has stated: they're completely useless. Never rely on one, ever.

Multimeters are piss easy to use. Buy one for $10 and read the manual.
