Hello, I've been thinking to give my desktop a boost for 2 graphics cards since I want to run my games at solid 60FPS or close to it at max settings (Either AA or not). I have space and my desktop runs pretty cool.
Here are my specs:
Asus P9X79LE
Intel Core is 4820k OC 4.5GHz
Gtx 660 twin frozr OC
16GB RAM
600W powerbox (I'm away from my house so idk what the model is.)
Monitor: Asus 27" 1920x1080 1m latency. Is 600w enough or do I need like a 800W PSU?
If I need a higher watt psu, please give me recommendations of what psu I should get. I greatly appreciate if you would recommend me a good psu. :D

You'll barely pull over 300 watts with one card. It is fully possible to run two 660's on a 660watt psu. But we need the model name in order to check if it is of good quality, otherwise you'd be better off gettings a new psu. from a company like XFX or Seasonic.

600W will do you just fine. I think you'd be surprised how little a system like that pulls from the wall. In fact, if your current PSU is not very good quality you would be much better off swapping out for a lower wattage but better quality power supply. Go for something like Corsair (avoid CX series), Seasonic, EVGA, XFX, or higher end Coolermaster power supplies. 450W should do you fine for that system, if you want upgrade room 550W should leave enough for a graphics upgrade, since 660 is a bit outdated now, even in SLI.
