A system with a GTX 690 needs a recommended 620w power supply. A 650w power supply from Corsair, Seasonic, PC Power and Cooling, XFX, Silverstone, Enermax, OCZ or Antec will assure you are fine.

As for RAM get 1.5v DDR3 1600 cas 9-9-9-24. Either Corsair Vengance or GSkill Ripjaws X would be my recommendation. Both are very good and both have a lifetime warranty. Go with whatever is cheaper.

you should get a 750 watt psu for room for upgrade in the future and you dont wanna strain the psu either

650ish minimum IMO. if you dont care about adding much to the build afterwords, pay for efficiency(silver/gold/platinum 80+) rather than more watts.(efficiency anyways usually have better 12v rails)

Thanks for all of the help I have decided to get a corsair professional gold ax850. I think it will leave room for upgrade :)

Thanks for the best answer but the AX850 will not leave you enough room to upgrade a GTX 690. All you could really do to upgrade it would be to add a second GTX 690 and for that you need a 950w power supply. So if you think you will add a second card get a power supply that will handle it.

Have you seen the price a 690 I won't be getting another one for a LONG time and that seasonic PSU looks pretty coll I think I might go with that one instead.
