    Take a look.
    I have no idea who's Npower but a Corsair CX400 is more than plenty for your setup.

    the 8 pins are just for stability it will still work as there are only actually 4 pins in the connector

    No. You should be looking at something more along the lines of 34~ amps on the 12v rail(s) combined. 25 is very, very low...

    Yeah i went through series of sites and wattage calculators and i seriously need at least 34amps on the 12V rail but m not able to decide weather to get a single rail wit 34-36amps or dual 12V rail wit 18amps on both of them????

    What difference does a single rail and dual rail PSU have???
    Any way thanks for ur replies guys :D
