I've been sticking with my Enermax PSU for quite some time. However, I just recently got in on the Buy.com deal for the Antec Neo 500W for $50 shipped. I was planning on using it for a secondary PC, but then after getting it, it seems really nice. I'm curious of the two, which is the better one? I'm currently running a single card setup, but I may move to dual 3870s or to a 4870 at some point. Obviously in Crossfire the Antec should run better, but for a single card setup, which is better? Note that the Antec has 3x17A 12v rails, while the Enermax has 2x20A 12v rails (I'm aware that more 12v rails doesn't necessarily mean better).
