It sounds like I got lucky. ;-)

Brand new Antec True550 and no ATX connector discoloration. The board
revision is the latest and I've gone so far as to augment the 5V rail with
the "molex tweak"

Sound advice. With the 9000, the 5V rail was either 5.01 or 5.06V (can't
remember). That's good news...
