As far as I can tell, it's not clear yet which component is at fault. All I have seen evidence of is that the ASUS and Antec parts are
incompatible. Yes, the motherboard works fine with other power supplies, but it's also true that the power supply works fine with other motherboards. The problem seems to be an incompatibility, not a straightforward case of a lemon product. If you look around, you'll find plenty of evidence that the NeoHE isn't the only power supply having problems with Asus boards. I don't think there's a clear case for who's at fault just yet.
Jvrobert, yours is the first problem I've heard not relating directly to one of three ASUS boards, and I'm still not clear what you're using anyway. So far you've mentioned three different power supplies:

First, you mentioned a NeoPower430. I can find no record of this power supply on Antec's site, perhaps you mean the NeoHE 430?
Second, you mention that you had second thoughts about an RMA for a NeoHE 430, which means you never tested a second model.
Third, you mention a 480HE. This is another non-existent model. The Neo HE comes in 430W and 500W models, there is no 480W model. There
was a 480W NeoPower, but it comes from a completely different line.
Can you clarify which unit you had problems with? If it was the NeoPower480, your experience isn't relevant to this thread, since it applies to an older model. If it was the NeoHE430, your claim that it's a problem with the power supply itself, not the motherboard becomes a little more credible.
