    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)
