Ain't hindsight a wonderful thing.

You think Antec will acknowledge the fault and sort me out with something stable? Maybe i could ask for a seasonic one? xD
The rails thing i pretty much ignored since my system is nothing out of the ordinary but i'm certain i've not got it all working off one rail anyway cos i messed around with the first one thinking that might be the case....not to mention the fact that the OCZ has two 25W rails only. Basically i think it's either the 3 or 5 volt fluctuation that is causing it. Can't remember if it's the 3 or 5 that give the unit the power up command from the mobo....hence i was wondering however whether i could simply modify a bios setting to bypass this. Is that possible? and if so would it increase the chances of any damage being done to mobo components or anything else?
The same model line isn't traditionally split between OEMs. You would have to ask for them to take your HCP model and give you something that is not a HCP model instead. Since they mostly like to replace with the exact same sort the person already had, this could potentially be difficult to get them to agree to. However, if you were successful in getting them to take the Delta model and give you a Seasonic other-model from where I sit you would be better off.
Not everyone agrees with me on everything, though, so keep that in mind.
In any event, it is entirely possible for a PSU with 4x 40A lines to fail on something a PSU with 2x 25A does not fail on as long as the total amount used is 41A or more. Not that it relates to this current problem in particular, its just worth mentioning.
The +5vSB line is what is always on even when the computer is turned off. It provides power to the power button and other devices necessary to potentially waking the computer up notably including all USB devices whether they can actually wake up the PC or not.
The +5vSB line on most PSUs does tend to deteriorate more rapidly than other lines most of the time, in my experience. They all deteriorate over time, but that one tends to go the fastest. If it were an old PSU we were talking about, I would say its entirely possible that the +5vSB line deteriorated to the point it wouldn't work anymore.
However, we are experiencing problems with apparently new PSUs of given model X and its pretty uncommon for a PSU to arrive new with a failing +5vSB line.
I wouldn't guess that the +5vSB line on the HCP 750w would be the fault, but its indeed possible.
The testing websites listed before might go deeper into detail about which specific parts they had fail in the PSU themselves, but I am just guessing it is something else.
In any event, I would say its better just not to use a spotty model and not to hope to get a good one of that type rather than one of the bad ones. It is easier to just get something a different model line. I would vote for trying to talk Antec into giving you a better reviewed other-model as a replacement.
