The Antec Smart Power is not as good of quality as Antecs TruePower line of PSU's.
I value my PC, and choose to only run quality clean power supplies with mine,
but the lower line Antecs should work, I just would not choose them.
True enough. The smart power is their bottom line. I know a lot of people will disagree, since there are some issues arising from the lower amperages on the 5v and 3.3v Rails, but I really like the NeoHE line as well. I use a NeoHE 550, and it works great. 3 12V rails, modular cables (a great feature that all psus should have, quiet, stable, and uses less electricity). Just don't use it on an ASUS SLI board.
