    +5V not showing on any hardware monitor


    Hello again

    I have a problem, or at least I think I have a problem. Just recently I went onto ASUS AI suite to check my fan speeds etc. Then I noticed that the +5V is suddenly onto 0.000. So then, I went to the BIOS to check it from there and it says N/A.
    The BIOS firmware isn't up to date but I have a feeling I shouldn't use this unless it is highly recommended for this problem.

    My motherboard: ASUS B85M-G
    OS: Windows 8.1 Pro and Windows 10 Technical Preview

    Why are you looking at the voltage for? Are you using a different video card, than the onboard GPU that came with your computer?

    I actually didn't look specifically for the voltage but it was a coincidence. I'm a person who kinda gets ''scared'' quickly when something is wrong with one of the voltages when I shouldn't be at all. And yes, I am using a different card then the internal GPU of my CPU. Never used the onboard GPU from my CPU.

    This is becoming more and more common and by "this", I mean more and more motherboards are going with +12V and not using +5 anymore (except +5Vsb standby). The Gigabyte board in this computer does not use or have a +5V sensor either. So I don't see any +5V reading with HWMonitor, Speccy or in my BIOS either. As long as your +12V and +3.3V are within ±5%, you are good to go.

    If your computer needed +5V and it really was missing, you would know it.

    Ah I see. I was just wondering if this might become a issue. But for the note, I have an ASUS B85M-G, not an Gigabyte model.

    I saw that. I mentioned my Gigabyte to illustrate it was not just ASUS.

    Ah alright. Well in this case, I hope this is a sensor problem and not an actual problem. But as you say, if motherboards don't need 5V anymore, then it shouldn't be a problem at all.

    Now if this is a sensor problem, is there any way I can solve this or should I just leave it and ignore it?

    I don't believe it to be a sensor "problem". More like there is no sensor because it is not needed.

    But if there were a sensor that had failed, there's nothing you can do about it because it is imbedded somewhere in another IC.

    But you can jam a multi-meter probe into the heart of your computer to measure the +5V, or better yet, get a PSU Tester like this one that has an actual LCD voltage readout.

    Ah, well I did saw though not long ago the +5V on my motherboard and on ASUS AI Suite. But yeah, if I really want to be sure about this, I better get that PSU tester.

    Not sure then why you would no longer unless the sensor did go bad, or there was driver update or BIOS update that changed.
