Looks good, but which 650 watt psu is this? a cheap PSU can compromise your whole system. You can get one that will work for your system relatively cheap. Get one by Antec (Antec neo series is pretty affordable) Corsair, XFX, Seasonic. And make sure it is 80 plus. A generic 650 watt psu dosnt always put out 650.
But like i said, its all looks good. Just dont cheap out on the psu
