In around 2 months, I will be upgrading my PC. I currently have a GTX 650 Ti. So i need an upgrade badly. These are going to be the specs:

Gigabyte GA-990FXA-UD3 (Rev. 4)
AMD FX 8350 4.0 GHz Octa-Core (not OC'd)
Corsair Vengeance 16GB (2x8GB) DDR3 1600 MHz (PC3 12800)
2x Geforce GTX 770 in SLI
6 fans. 2 are LED fans.

Whats a good PSU for my build?

Visit your GFX card manufacturers web site for needed CPU size.

http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-760/specifications

Thermal and Power Specs:
97 C - Maximum GPU Temperature (in C)
170 W - Graphics Card Power (W)
500 W - Minimum Recommended System Power (W)
Two 6-pin - Supplementary Power Connectors

If overclocking seriously, id suggest a Corsair HX series or Seasonic X series..... if moderate OC, Corsair TX V2 series, or XFX Core Edition.

So 500w for system and 1st cad + 170 for 2nd

Id suggest a 750 watter
