    it sits at 11.58v but for some reason drops to 11.43 and crashes my pc
    yes I do have an oc system running 12hr a day .. but i'm sure it should be ok

    Re: tx 750

    Hi flearider, based on the 12V values you have mentioned, 11.49V on the 12V rail is a value that is well within spec (+/-5%). Since your system is OC, have you tried running on default settings and see if your system will behave the same way? Does it only happen when you put load in the system? or it happens randomly? regardless even if the system is just on idle. It's probably worth checking the RAM as well. Run memtest and see if any of the RAM generates error. When you run memtest, try running it one stick at the time. That way you can really isolate each stick from one another.

    Re: tx 750

    ram's fine and dandy and it's 11.43v which is boarder line ..
    and yes it happens at odd times idle, load it just drops the last 2 I had replaced ..the first went to 11.33 and the second was nearly the same out of the box .. just thought it happens some times which it does ...
    but now with this one starting to do the same .. just get that all over dark feeling ..

    Re: tx 750

    what are you using to test this, on board or a certified calibrated multimeter ?

    Re: tx 750

    hwmonitor ,AIDA64 and I don't see a problem using them ..
    the out going power of the psu might be fine but it's whats happening on the draw that's the problem

    Re: tx 750

    the thing is they are not 100% accurate, the only way to be sure is with a decent multimeter.

    my old rampage extreme has tap points and my expensive fluke multimeter shows the onboard is .3 volts out

    on the newer boards I can't see it being that far out .. and seeing as I've had 2 changed out already .. well to me it show's theres something wrong ..
    but i'll wait till it drops a bit further and put in for yet another swap out ..

    Re: tx 750

    enthusiast boards that have tap points are for those that know the onboard chips that read the voltage cost pennies not hundreds of pounds, just saying m8.
    if they were so good asus wouldn't still be putting tap points on there top of the range latest release boards would they ?

    I think you're trying to blame this on something other than your 5ghz overclock.


    run it at stock and see if it happens, i will put a fiver on not

    +1, try this and we can go from there. We just need to eliminate the overclock aspect out of the equation.

    so your now saying my power supply is no good for overclocking .. ??

    "yet still more than sufficient to cool the internals of the system, reliability and stability are no longer worries for the gamer, overclocker or enthusiast and high-end system builder."
    http://www.corsair.com/tx750w.html

    why eliminate something it is suppose to handle ?

    Re: tx 750

    no we are saying your overclocks probably not stable and you are trying to blame this on the psu when it could be the settings your using, the cpu not capable of staying stable at the 5ghz overclock.

    so if it works fine wihtout the overclock you need to take a look at your settings and stop blaming the psu.

    unless of course you provide a calibration certificate for your multimeter to help prove the voltage dips below the 5%.

    Re: tx 750

    hmm lets see no crashes in what 4 months .. then a voltage drop and crashes ..
    plz gonzo your not invited to this ..so unless you a corsair rep plz keep your post to yourself ..

    and of course less stress on the psu will deliver different results .. it's not magic it's logic ..

    I overclock .. the system was stable now it's not the psu has had a voltage drop .. the psu states it's for overclockers ..
    i'm not new to this ..this is far from my first build ..
    I await a response from the corsair rep .. as this is what I asked for in my first post ..
    now plz respect what I have asked ..

    I will back out as you seem to have no clue as to an overclocks long term stability, good luck with getting a 3rd RMA.

    Re: tx 750

    normally there as stable as the parts .. and when it drops there warranty says rma
    but unless they change it out for something different .. i'd ebay it straight away ..

    Re: tx 750

    flearider, please be considerate to others that are trying to help you. We are only trying to look at ALL possible causes on why your system is behaving this way. I myself, suggested to run your system on default settings - It does NOT mean that I am doubting your overclocking skills, nor implying that your settings are incorrect. I just want to make sure that we isolate one component at the time when troubleshooting the current problem, that's all and nothing more.

    My request I think is reasonable, run the system under default settings and see if the system will behave the same way.. now if it does, then we can look at other components (including the PSU) that could possibly cause the system being not stable.

    If it's indeed the PSU, I will have no problem sending a replacement, I'll even cover the shipment both ways, we just have to make sure that we are addressing the issue accordingly.

    If it's indeed the PSU, I will have no problem sending a replacement, I'll even cover the shipment both ways, we just have to make sure that we are addressing the issue accordingly.
    i'm sorry if others want to butt in that's up to them and seeing as this is the corsair forum and I did ask for a corsair rep then I asked if he wouldn't post here ..simples

    now would you like me to underclock the system how about removing the hd's and a lower vid card .. if everything is run at default how would this stress the psu like it is when o/c ? as I don't run the system at default how is that going to help ???
    like I said less or more stress will deliver different results so running it at default the 12v rail will prob show 12v+ this still does not mean the psu is in anyway stable it will just show it can run at that power draw ...

    so yes what your asking has no logic and is not reasonable .. but if your saying the 4 month o/c is now not stable because of a different component .. then that part i'd challenge by saying the only thing that has changed is the voltage drop ..
    What does it matter now if men believe or no?
    What is to come will come. And soon you too will stand aside,
