Changed PSU,when connected 24pin,no power

It shouldn't make any difference, as the sole purpose of the +5VSB is to power the logic circuitry that controls the function of the power button (together with WOL and other standby functions).

If you swap the PSUs back over (you said that the problematic unit worked in its original system), what voltages are you getting on that line then?

It is quite possible that it is the PSU, and that the +5VSB circuitry within it (transformer, regulator, etc.) is beginning to fail and isn't able to maintain the correct voltage output when under load.

You know the saying "if it aint broke,dont fix it"? I am not gonna put this "faulty" psu back on its original board,as i have spent too much time getting the other systems to run perfectly.

If this psu cant keep the voltage to its designated power on a board that runs fine on a different psu,then by that logic,the psu is bad.

And since i already ordered a new one, i am not gonna spend any more time on it..

Thank you though for all your help, even though it might not be satisfactory i just throw the damn thing out .. Must be a reason no one sells north q psu´s anymore

Found this on wiki

Cheaper and/or lower quality power supplies do not follow the ATX specification of a separate monitoring circuit; they instead wire the power good output to one of the 5 V lines. This means the processor will never reset given bad power unless the 5 V line drops low enough to turn off the trigger, which could be too low for proper operation.

TsunamiJhoe Glad you got it sorted out I figured that was the problem as well cause this has happen to me before I think it is true some PSU just don't do what they are supposed to especially one's with lower quality Corsair will do you right .....

The old board it powered with an older amd phenom II x2 must not have been as particular as the core i5. goes to show ya,never buy cheap crap ,well unles the expensive crap is made in china ;-)

OK,new psu did the trick, however my stupid retailer did the newegg trick,and sent me the the wrong psu. I ordered the v2 of the corsair tx650,and they sent me the v1 which apparently is a cheap china model that is really bad craftmanship and cheap components, and a lot of people are reporting this as very bad,so i have sent it back to my retailer demanding the v2 version,as v2 apparently is made by seasonic,and should be a lot better than v1

That's a common trick by retailers it might be the sasme type of package but not the same version and they tryed to do that same thing to me with a Asus board and the guy looked here it is and im like no it itsn't that is verson 1 i wanted version 2 so of course i made him do some work and got the right one

People think you wouldn't notice but as costly as this hobbie is i have to pay attention because these people love passing off refurbished rubbish
