    I've seen several Newegg psu customer reviews where different brands or models had issues with the Gigabyte X58 mobos. In one review, the manufacturer responded that there was an issue with one of their 750 watt units, but this was limited to the earliest versions and that this is no longer an issue with their later "updated" units. No other details were given.

    The problem might be that some motherboards are a bit too picky about their voltages. I'm pretty sure that the ATX_v2.2 spec for +5VSB is plus or minus 5%, meaning that this voltage is in spec when it is between 4.75 and 5.25 volts, and this is the same rating for the regular 5 volt psu rail.

    +1 ^^ Yeap!

    I just dug up the thread here not too long ago in regards to this, although this brand/model was not one mentioned it does not mean it did not apply.

    BUT.... This sounds to me like you may have a short, or bent CPU Socket pins. This is often the issue presented when such things happen.

    You are sure you have the 24Pin and 8Pin power cables connected to the board correct? You have your memory in the correct slots right? Unlike older gen boards, with X58 you need to use the further slots. You need to use 1, 3, 5 (Physical 2, 4, 6 White)

    Are you sure also that your GFC Card works? If you are not sure on the GFX please test it in another system, I recently was testing a GFX card with a bricked BIOS and it caused the system to fail to start at all.

    If you are sure your GFX card is fine, then please build the system outside of the case with the Intel stock fan on a wooden table, or cardboard box and then test with only one stick of memory (In any white slot) and your GFX card only, no drives, ect.

    Then if it boots you know you either had a short in your case, or with your cooler. If it does not boot still, try clearing the CMOS to see if that helps.

    If none of that helps, you may have a bent CPU Socket pin, or several. You may want to check this first. When checking PLEASE Be careful, use a bright light and look closely for anything that looks bent or out of alignment.

    I tried all of the normal tests, i work as onsite-support so i know how to check for errors.
    None of it has been successfull.
    But i can say one thing positive.
    When i tried my old psu, a Antec 500W Earthwatch, i got enough power to the motherboard so that the cpu fan started to spin and it began to start boot for a few seconds but then it died. Just like when you try to start a car that's a bit sour. I thonk that it was too weak to fully give the power needed to go on. With my new psu i got no response whatsoever.
    I'm going to send it back to the webshop so they can test it.

    Hi,
    my problem was solved with a new PSU (though I got an irritating coil-whine), but at the first place I got no power at all (no phase leds) in contrast to your case...

    I think that the 500W psu should be more than enough to boot your system (mobo, psu, ram, 1 gfx) so if your system fails to boot on both psus then the problem is probably elsewhere. But if you have a miltimeter handy try measuring the Vsb pin of the psu, since the mobo seems indeed a bit picky about this one!
    regards

    Well krampand, it does sound like maybe your PSU is to blame here. Did you check for bent pins just to be sure?

    Just wondering. Let us know what the web shop finds, if you test another PSU, or if you checked for bent pins.

    Does that mean then that there's something wrong with the memory?
    Sorry the resurrect this thread but I'm currently having the same problem as krampand. But my power supply is Seasonic M12D 750w. Is the problem really with the power supply?

    Have you checked to be sure you don't have any bent CPU Socket pins?

    Sorry, have to ask, you do have the 24 pin ATX Cable and the 8 Pin ATX 12V EPS cable connected to the board right?

    Memory in the white slots?

    What CPU are you trying to use?

    thanks for the response. yes to all the above. my cpu is 930. sent my motherboard to have the shop test it and they said that there's nothing wrong it. They even updated the BIOs. So I'll have to assume it's either the RAM or the PSU. Now, I've tried the PSU with my old E6600 computer and it works with it. I have no way of testing the RAM.
