520 watt seasonic psu good enough for 660 ti or 670?

Not really much to add except I have a g45 motherboard with i5 4670k, velociraptor, samsung 840, two optical drives and six case fans.

yea should be fine, the 660ti only need 450W as per NVidia.

Yes a quality PSU like that is.

That system will be hard-pressed to draw 300W under 100% load. So yes, 520W more than enough.
