I have very specific plans to upgrade my setup, and am looking for advice.

I work as a LAN admin, and have been building my own systems for years, but I have a couple of questions regarding my plans, and this is the best place to place them.

Right now, I am I working with:

ASUS P8P67-PRO REV 3.1
I5-2500k@4.3ghz (NOCTUA Air cooled (love it)
SLI EVGA GTX 560ti 2GB
8GB Corsair Vengeance Blue

In the next few days I am planning on buying an I7-4770K, using my same air-cooling system, keeping my RAM, and upgrading my MOBO and GPU to a 780ti.

This is the MOBO I am planning on using http://www.newegg.com/Product/Product.aspx?Item=N82E16813132118

I am not planing on overclocking beyond 4.2ghz, but I really get fuzzy when it comes to power consumption.

Will this system be able to handle the OC@4.1 or 4.2 Ghz with a 750w PS?

Oh for sure, no worries. One thing I might think about is getting a 4790K, it is a new Devil's Canyon CPU which is very similar as Haswell and the 4770K, but has much better overclocking performance and lower temperatures. That means you can push it farther than you would a 4770K. And I believe the 4790K and 4770K are very close in price.

And no, you have nowhere even close to worrying about power thresholds.

With power consumption, you're looking at amps more than anything, the 750 watts will cover everything overclocked, but It's important to get a quality PSU. As long as you have the quality part under control, you'll be fine. Also remember, some of the older PSUs don't play nice with the new Haswell parts. Unfortunately, I don't know enough in this area to know if you're endangering your system or not. Gotta check back later I guess, hopefully some one will know for you.
