I have a Antec True Control also, but I use a DFI UT 250 and from the beginning it would false start but only after running for awhile. The next day after sitting for a few hours it would start no problem, but when its warm or been running and I have to start it I just turn down the 3.3v line in the front panel and it boots right up and as soon as it does I crank the 3.3 line back up and all is good.

It probably doesn't have much to do with your problems but just an idea.
