New i7 950 System needs a PSU

[morencyam]

Hello all

So, i'm finally getting ready to build my new i7 system but i need some advice. at the moment my system specs out as such:
Asus Sabertooth x58
Intel Core i7 950
6x2GB OCZ Reaper DDR3 1600 CL6
2x EVGA GTX470 SLI
Crucial RealSSD C300 64GB boot
2x2TB WD Green for storage
2x sata CD/DVD 24x burner

i still have yet to pick a PSU, which is where i need your guys' input. i was looking at a few articles and reviews and found some saying that 2x GTX470 SLI system really only requires 800W max.

i found a few PSU calculators online and filled those out with my specs and none of them recommended anything over 850W.

i would like to get some input from users with a similar set up just to ensure i go big enough, but not too big.

i plan on OC'ing a bit but not until i get a watercooling loop set up to run on that PSU as well sometime in the future.

many thanks to any and all advice/input

Budget=~$200

I love my X750 Series Seasonic, silent and 90% efficient.
I think there is a better PSUs.

go to jonnyguru.com
and go through their PSU reviews.

i've seen a few good reviews on seasonic. do you think 750 is enough power for my system?

ide go atleast 850 if u plan to oc the cpu and gpus, like the corsair ax850 thats a seasonic or the tx950 that is a seasonic or cwt (im not sure on the 950 but its a bronze so i would guess cwt)

i was leaning toward XFX Black Edition XPS-850W-BES 850W

those xfx are bad they will shut off once if u overload them then they will kill your system if u do it again. look at the JG review on it

if u want cheap the corsair tx is better and cheaper than that

zanzabar is right you need a quality 850 @ a minimum

personally i went with an antec tpq1200

What about this guy?

i would say no since i dont trust abs but i dont know whats in it so i cannot give a definitive answer, the psu is not something that u want to skimp on it will control how much line noise u get on the rails and that controls how u can clock, and you dont have to keep buying one when u upgrade if u get a solid unit

[morencyam]

Okay, so stick with a brand like corsair, antec, or coolermaster then?

how about this one then? Or do you think that is over kill?

coolermaster is not a reputable psu brand, corsair seasonic or if u need cheap and low watt then ocz modX pro, thats all i would use in general unless u look at reviews for the product from some ware like JG.

there are other brands with some good units like antec, xigmatec, pcp&c/ocz (high wattage) but u need to make sure that they are good unit

I think I'm going to go with the corsair professional series ax850. I really like the all modular design, the 80 plus gold efficiency rating, jonny guru recommended, and should power my system with some head room for oc'ing.

Thoughts?
