Yeah it is plenty, you will be using probably around 300 W at peak load so that PSU is plenty, it also leaves you plenty of room for future upgrades and is a solid unit that shouldn't give you any trouble.

+1 The XFX is more than enough and an excellent PSU.

More than enough, big 12v rail, enough for future expansion. Your set!
