I am about to purchase another 770 Dual Superclocked Edition but i am wondering what PSU i need with it.

I currently have: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Is this PSU good enough for the following:

It has enough wattage, but it's a poor quality PSU that exhibits very bad ripple (bad enough for the PSU to be rated as a fail in the review over at overclockers). I wouldn't personally want to risk my hardware on that PSU.

If you did want to replace it, tristanturner2, the EVGA SuperNOVA 850 G2 would be a good choice. A remarkably well reviewed, well made, yet affordable PSU that came out fairly recently.

Thanks for the reply! what if i had another PSU with this one to make dual PSUs and run 1 gpu on each, would that be good? like the PSU i have now and the one you just told me to get? I have a corsair 900D so i know i can fit both PSUs in my case

The EVGA SuperNOVA would be more than enough to run your 770 SLI and overclocked i7 system on it's own, unless you're planning to add more components?

I wouldn't personally recommend running dual PSUs unless you absolutely had to, as they can be tricky to get to work (plus the already mentioned danger with your current PSU's ripple issue). Also, running with the components split between the two PSUs would likely be less energy efficient, as most of the time (when not gaming, light gaming, or playing a game that doesn't support SLI) one or both of them would be running such a low load that they'd be in the very inefficient part of their energy efficiency curve.

Basically, what I'm saying is stick with one PSU if at all possible; there will be less headaches in the long run.
