Which psu to choose?

[LinkedKube]

*Spelled "Choose," wrong too*

Through overclocking, benching etc, I've learned the long way that my psu in inadequate. It went poof.

I know a little about psu's, more so about the hardware that they can work with because of simple google searches.

I'll give you a list of items I have in my current system.

core i7 965. Was at 4.1 ghz
Asus Rampage 2
12 Gigs of ddr3
G skill SSD 128 GB
G80 ultra (Been sitting on my hands about upgrading to two 4870 x2's

6 led case fans
2 drives

I'm planning on doing some aftermarket stuff(well some more) in terms of a 220 watt peltier build for my cpu( I may get a dedicated psu for it.) Along with a complete watercooling loop (cpu+gpu's maybe NB, probably not though)

Choices of psu's I'm looking at.

My issues are...
1. Having enough power for everything I want to connect
2. The listing of 12v rails are 1-4 or 6 etc. Some give more power than others. How am I to determine the difference.
3.Does efficiency rating effect constant power output?

google psu calculator - add 30% to the results.

different rails have different connectors. Also you can test with a multimeter if unsure

#3 - yes (but in quality PSUs shouldn't matter)
