Hey guys,
Thought I'd ask here as I've been scouring the webbernet for info.
I picked up a nice OC'd bundle from OCUK a couple days ago and go to stripping out my old stuff and putting this nice new Gigabyte GA-X58A-UD3R in its place.
I decided to "upgrade" my current Enermax 650w PSU (about 3+ years old) to a "newer" Enermax 1000w galaxy I had lying around. I actually bought that about 2+ years ago and simply never used it.
So anyway, system all fitted, 1000w galaxy fitted, etc, start up -- it starts for about 2 seconds, shuts down. Then starts up for a second or so, shuts down. This happens repeatedly until I manually turn off the PSU switch to wit it then beeps twice - the PSU that is.
I look it up in the manual and it suggests a possible short. Sigh.
Whip the board and bits out of the case, check all areas for any loose wires, screws touching anything, etc. So now I have the entire system outside of the case sitting on foam/boxes away from any metal bits, etc. Trying it again, same thing. Grr.
Ok, swap back to my old PSU - the Enermax 650w. Flippin hell, SAME THING! Now I'm thinking it's the mobo - but I've never had a prob with gigabyte boards and OCUK have overclocked this one for me themselves and I know they wouldnt send out a duff one.
So i google and google and eventually hit this link : http://forum.enermax.com/showthread.php?p=383
I suppose my question, after that huge diatribe, is has anyone every had a similar issue with an Enermax PSU?
I'm surprised that both of my Enermax's perform the same but then, they are old and this Gigabyte board is new.
Have a new Corsair HX1000w on the way to I hope that sorts this out.

After checking and simulation with Gigabyte, we know what’s wrong.
Every PSU has an output timing control signal to tell MB if PSU is ready or fail. There is a PSU design guide to specify this signal. On the other hand, MB also has a corresponding control to recive the message from PSU. MB would also add a resistor on that control circuit IC, to protect the IC from interference (and some MB would not have that protection). Such resistor’s value would be vary by companies and models. This variation sometime confuses PSU, as certain resistor value would pull the PSU timing control signal out of range, making MB though that PSU is not ready, and making our Galaxy PowerGuard sending error message. As the result, system would not boot up.
Our Galaxy setting works fine with most MB models introduced before mid-2007, and a lot current new MB models. Yet we notice that some MB changes that setting from 2008, making such possible incompatibility issue happen when previous design ’ PSU meets latest MB.
