Need help with psu for new build

[Maxitout]

I'm starting a new build that i would like to use for several years and need some help selecting a quality psu that will fit my system needs.
I already have a phenom II x4 965BE 125w (might upgrade to a fx6300 or SR in a year)
I also have have a sapphire hd7770 and considering crossfireing with another hd7770 at later point if one isn't enough for me
I'm going to be using the Asus M5A99X EVO R2.0 MoBo
8gb 1600 RAM
1Tb 7200 HDD
and going to add a SDD when i can afford it.
going to be running 5-6 case fans.

Now if its possible i'd like to find a good quality psu to fit these specs for $70 can go up to $90 after rebates.
i've done a lot of looking and like corsair,thermaltake, OCZ, and xfx but i dont have any experience. So could someone give me some options.
thanks

how do those dual rail PSUs work i don't think i understand them.
the rails amps can't be combined and if i remember right the 7770 needs like 28-30amp, this psu has 24amp/12v rail
sorry if i don't understand that properly

I think you have that wrong. I don't have one on hand but the HD 7770 draws about 200W which is about 17A. Now with inefficiency I could see that going to 20A but not 28-30A

If you are really worried about it use this one
