So I built my first PC 2 months ago, pretty happy with it and now that I got a 4K monitor I want to make sure I have the smoothest graphics in game, so I'm opting for SLI. Here's my current build:

http://au.pcpartpicker.com/user/Crushader/saved/Z7VD4D


If I'm to get another GTX 770 to SLI, I need to upgrade my PSU as well. My friend kept telling me I shouldnt get a big capacity PSU more than what I needed because of the overhead (?) hence I only got a Corsair CS650M and now it is not enough for me to handle SLI. An estimation of 700ish W for the new SLI set up, so what is the best PSU I could get for it? (I plan to install an AIO CLC to replace the Noctua I have right now as well)

I'm thinking something along the line of Corsair AX850 or Seasonic SS-1050XM, would 1000W be too much? Full modular preferred

Here's my upgraded list of parts:

http://au.pcpartpicker.com/user/Crushader/saved/YqJgXL

An extra 8GB RAM, NZXT X61 for placeholder, will replace it with Swiftech H220-X or Fractal Design Kelvin S36 when they release, AX850 and of course the 2nd GTX 770.

Feedbacks appreciated!!

Tehe Corsair ax850 would work fine for your additional gpu

There is no such thing as too much on PSU since the PSU needs only to deliver the amount of power that the components pull. For GTX770 SLI a quality 750watt will do the job and 850 watt will give headroom for overclock.

750w+ would give you a good amount of head room without being overkill. Have you thought about selling the 770 and just getting a single faster GPU?

Yes, I have! Was thinking of letting the 770 go, and get 2x 780 or 2x 770 4GB. But I dread selling used PC parts, plus I already ripped the stock fans out of the 770 and replaced with ArcticCooling fans with a T mount to avoid card sagging (damn you ASUS for crappy design)

What would be a great PSU between 750-850W?

generally anything from Antec, Corsair, Seasonic or XFX you cant go wrong with as for a specific model just depends how much you want to spend, how much efficiency you want.. I normally try find a review where they load/ripple/noise test before i buy a psu.
