All the components are compatible and will fit in your case. But I would go for HX or TX series PSU's from Corsair or XFX. GS series is not that good. GeForce GTX 780Ti - requires 42 Ampere on +12V rail and a 600W PSU minimum, so a 650/700 PSU will be enough for your current setup, unless you plan on OC or future SLI.

And you can go with this cooler :
