As for the Corsair vs Seasonic, there's really not much between the two. They're both based on the same platform (Seasonic make the HX series for Corsair). The Corsair will be quieter, given that it doesn't have the rear fan, has a 5 year vs 3 year warranty, is generally cheaper and has, IMO, a nicer cabling system.
For those reasons I'd probably go with the Corsair, but they're both superb PSUs.

Would a Corsair 520W be too overkill for the following system?

No, the Corsair 520W would be a good choice for that sort of system.

Just a final question. Is the Corsair 520W a modular psu?

Yes

I have read from Ceewi1 PSU guide that a modular psu would have lesser efficency than a one without.

Praetor wrote that one, not me. I suggest reading through Modular Power Supplies: The Reality of the Resistance, as it goes into the issue in some depth. Suffice to say the effect is not very significant, and is, in my opinion, easily outweighed by the convenience of having a modular power supply.
That said, if you'd prefer to go with a power supply with fixed cables, the Corsair VX550 is superbly priced (significantly cheaper than the HX520), and just as good from a quality standpoint.
