How much difference is there between these two power supplies (Antec PP-412X vs Antec TruePower 430)? I have a dual athlon mp 1800 rig on a tyan mpx board that i haven't yet put together. I'm getting an Antec Case and was wondering if the TruePower was that much better than the PP-412X? I'm not really knowledgeable w/ pwr supplies so I don't really understand the differences in rail ratings and whatnot if someone could help me out. It would save me about $30 to go with the pp-412 in the antec case instead of the truepower. Anyone know somewhere cheap to pick up a genuine antec case? Thanks.
