Sounds like you haven't checked out Antec's truepower supplies yet.

Adapting ATX plug to this AT plugs using cut off ATX extension
spliced to AT plugs is trivial. Power on wire is active low, pull
that down to ground to turn on.

Oh, yes, they do have seperate AT style plug for 3.3V function.

Antec's truepower series design is seperate 3.3V and 5V circuits, not
combined, most typical power supplies even branded except Antec
are not good. Easy to see if label says combined max wattage for 5V
and 3.3V then it is shared circuit which is not what u want.
