Help selecting a psu and understanding psu differences

I need a hand choosing a psu, and I have a lot of questions, some of which you might need to see my parts list for, so here it is: http://au.pcpartpicker.com/p/snZNt6 I'm open to any other constructive criticism, but I'm not asking for it since this is the wrong forum for that. Ideally, I'd like one that can power 6 sata drives, since thats (as I understand it) the most the mobo can handle, and when/if I get more money I'll probably add some more drives. Modular'd be nice as well, but its not necessary.

Whats the difference between a 24pin connector and a 20+4pin connector?

12v rails, what are they and how many do I need?

Whats the difference between a silver and a gold certification?

Should I be choosing a psu yet or should it be the last thing that I choose? (I'm not adding a lot of the things that are left off on the list, but I figure thats ok, I'm yet to add more case fans tho)

I think I have more questions, but none come to mind, I'll just add them in later if I remember. Thanks a bunch!

The difference between 24pin connector and 20+4 connector 24pin is only compatible with motherboards that have a 24pin motherboard connector whereas 20+4 are compatible with motherboards with 20pin and 24pin power connectors. Most new boards use 24pin power connectors so either is fine really.

Gold and silver certification just shows the efficiency of the unit. Take a look at this:

The psu is pretty much the last thing you choose. Seeing as you now already have most of your parts you could pick a psu now.

For this build I would recommend a 750W unit such as the EVGA B2, G2 or a seasonic, antec or xfx unit of comparible quality.

Thanks, that helps a lot.

I think I'll add the gold rated one, its not much more, and if its going to be better in the long run it'll be worth it.
