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.
Lol i hear you man they are a lot of money and great choice my little brother has that seasonic psu has had it for over six months not a single issue hes running 580's in sli though he doesn't have a 690 hehehe
