Default New Seasonic PSU & SLI Concern

Hello everyone, new here and Im not sure this is the appropriate place to ask this question, but I thought it was best suited.


Long story short:
--- Seasonic x750 ---
Will this be good enough for GTX 570 Superclocked in SLI?
The rest of the build will be a i7 2600 or 2700K at around 4.5Ghz OC, 3 WD Black HDs, 2 SSDs, BluRay Burner, and a X-Fi Titanium HD sound card, All in a 600T case

I have tried searching for a answer but end up right back where I started. Everything from, sure it will be fine to NO, at least 850W is needed.
And some saying its OK so long as nothing is OCd....


The Long Version:

I am in still in the process of building the new PC.
Basically, I already have everything except the Motherboard and CPU, which Ill be ordering soon.

The original plan was to use the eVGA P67 SLI motherboard & i7 2700k, with my current eVGA GTX 570 Superclocked GPU.


But, I am now considering the eVGA P67 FTW K2 with the 2700K, and grabbing a second GTX 570 Superclocked to run SLI.


The problem is, I now already have the case, power supply, as well as everything else here, and am unsure if it will actually be enough power if I do go with the bigger motherboard and a SLI config.

Im also not sure if it would even be worth the effort to try and exchange for something else by the time shipping costs etc are added.


Any advice appreciated.

You'll be fine.. you'll probably be pushing >100% load unde Furmark + Prime95 sessions with bothe the cards and the CPU overvolted but that's not an issues considering you're running them on a high end PSU which behaves quite well when slightly overloaded.
Outside of benching session you'll never touch 700W

Thanks so much

Yes, My CPU will be OCd, and the GPUs will remain at the factory setting (Evgas Superclock OC)
I do run Prime on occasion when checking the stability of the CPU, but have never used Furmark. Ive always hear its too stress full, and the power it pulls is no where close to a real load.

I think the most stress full thing I do is 3DMark 11, or possibly evga OC scanner if checking a possible problem.

So, it would seem I should be just fine with the PSU under heavy gaming loads


My main concern was for games that that will use close to 100% GPU use, as well as taking advantage of all 4 cores of the 2600k.
I just wanted to be sure that when they were all being fully utilizeed, all would be OK. (In a real game game load not synthetic)


I do appreciate the insight, I feel better now.
Think Ill go ahead and go the SLI route. Must admit, Ive always wanted to try it, just been afraid to.

Nothing to be afraid of, you're perfectly fine
