Also, I don't mean to sound cynical, but the PSU I recommend is 20$ cheaper.
It also provides 30W more power, and has 10% more Amperage on the 12V rail.
And since it's XFX, it's top notch quality because Seasonic make XFX' PSUs (if you weren't aware, Seasonic are the absolute leader in PSU manufacture - ipso facto, the XFX PSUs are mint.)
Antec's are good. But not as good as XFX/Seasonic.
