    Default Gigabyte X58A-UD3R | Turn ON briefly, turn OFF then turn ON when unplugged from wall

    Hello,

    I just build a new computer with a brand new Gigabyte X58A-UD3R (rev 2.0) (BIOS FE1) and the computer is running flawlessly.

    However, something is strange or maybe normal.

    When i unplug the PSU from the power outlet and plug it again into the wall, when i press the power button, the motherboard turn on briefly, turn off and then turn on again and windows bootup as normal.

    The motherboard do that only when the PSU is unplugged from the power outlet.

    PSU is a Corsair Pro Series AX750

    Your advice ?

    Yep my setup does the same when I start the computer after the power has been switched off at the socket. I have a X58A- UD3R, with an i7 950 and a Corsair HX650 PSU.

    I have looked into this issue and I believe that it may be caused by specific combinations of motherboards and PSU's.

    What I believe happens is that when the PSU is powered up the first time, after pressing the start button it takes some milliseconds for the PSU voltage outputs to stabilise. During this time the motherboard waits for the Power OK (or good signal) from the PSU before booting.

    If it does not receive this signal after a set time (unknown) the motherboard forces a re-boot and again checks for the Power OK signal. By this time voltages have stabilised within specific parameters and provided the Power OK signal is present, the system boots normally.

    I dont think that it is a major issue, more of an annoyance - I even logged a service ticket with Gigabyte, but apart drom reseating RAM and CPU and checking connections, they could not offer a solution.

    It is possible that other PSU's may not do this, but I have no idea which ones might work - it may be that a number of PSU's may be a just bit slow on issuing the Power OK signal.

    Provided that your motherboard is working OK in all other areas, I dont think that you need to worry.

    Hope this helps.

    Default Gigabyte X58A-UD3R

    @Rebel801 :


    Thanks for your help.

    I'm glad to know that i'm not the only one who have that strange or normal issue.

    The motherboard seem to work well for the moment.

    CONFIRMED :
    The computer to my friend with a Gigabyte X58A-UD3R and PSU Corsair Pro AX750 (same PSU as me) do not do that !

    Thanks - that may be useful in determining which PSU's are more likely to have this issue for other members. At this stage I dont intend to replace my 6 mth old PSU, and it may not change the boot performance.

    I swapped out my Ep45 ud3 for the X58 and the previous motherboard did not behave this way. Its entirely possible that Corsair PSU's take just a little longer to stabilise volts.

    Cheers

    are you using the latest bios? sometimes it happens with older bios's but i think it does it due to the dual bios,it boots up and checks the bios then restarts and applies the bios settings,normally only from cold or when power has been disconnected

    my mb used to do it but with newer bios's it doesnt anymore

    Same for me. My PSU is brand new and is warranty 7 years.

    Yes, i use the lastest BIOS available (FE1 beta).

    Same here - my board had FB installed when I first setup my system and now I am using FD and there is no change in the boot behaviour. Yeah it could be due to the Dual Bios arrangement, but then some people do not have this issue, so given that the motherboards or PSU's are not faulty, the issue must be because of the way the 2 devices communicate with each other.

    I will keep updating to the latest bios as they are released, to see if the issue is resolved.

    its not psu,if it were psu it would reboot all the time when playing games ect not just at start up,my mb used to do it,if its from cold then its to be expected,my mb doesnt do it now but i hardly ever let it go cold/turn it off,had same issues with s3 sleep now its fixed through latest bios's,maybe newer bios's will help fix it,if its only doing it from a cold start then i wouldnt worry about it too much

    I agree - its nothing to be concerned about and TBH I rarely turn off the AC supply to the PC powerboard which also supplies the router etc. Probly the only time I switch off the AC is if I am working inside the PC case - then I use the PSU AC off. The last point is important IMO because even if the PC has shutdown, if the AC is still on, then power is still feeding the motherboard and you should not plug in or remove pci cards, RAM etc without shutting down the supply completely.

    As I said earlier, there is nothing wrong with either the PSU or the motherboard, but rather the way the 2 work together.

    Cheers

    CONFIRMED :
    The computer to my friend with a Gigabyte X58A-UD3R and PSU Corsair Pro AX750 (same PSU as me) do not do that !


    However, the memory brand is not the same as me. Kingston HyperX for him and Mushkin for me.


    My memory:

    Mushkin Enhanced Blackline Frostbyte PC3-12800 12GB 3X4GB DDR3-1600 CL9-9-9-24 Triple Channel Memory

    I removed all 3 sticks from my motherboard and it stopped to turn on, turn off then turn on cold boot.

    I did a test with a 2gb samsung and i have the same issue (I found only that memory stick).
