Hello,
I'm building a computer for the first time, but I'm not entirely sure what Power Supply to get so that I won't have to change it later.

I'm planning to get the Asus Maximus VI Formula when it's released, with the Intel 4770K. I'm planning to overclock that to 4.5 GHz or greater. The heatsink is the ZALMAN CNPS12X 120mm Long Life Bearing High Performance Triple Fan CPU Cooler, and the GPU is the EVGA Superclocked GTX 780 with ACX Cooler. I'm planning to put in 3 of these in total later. What PSU is enough to have room for all these components and other pieces of hardware like peripherals?

If you have any suggestions for editing the specs, please let me know as well.
Thank you very much in advance.

Not sure what "I'm planning to put in 3 of these in total later" means, but I'd stick with 1 x GPU.

Here is what I'd look at with what you've partially listed above:

An AX1200i will do, however getting 3 780's will probably not scale good. You will only gain a few frames on specific games, and lose FPS on other games. My best recommendation is to get 2 780's, unless you want massive headaches.

Alright, but gaming is not the only thing I will do on this system. I will also be doing heavy video and photo editing, and I won't be building a new one for...quite a while. So would a cheaper alternative be as futureproof?

For a system using three GeForce GTX 780 graphics cards in 3-way Tri-SLI mode NVIDIA specifies a minimum of a 1100 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 88 Amps or greater and that has at least three 6-pin and three 8-pin PCI Express supplementary power connectors.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the most important factor.

Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

What is your power supply budget amount?

Are you really needing that big of a PSU? Are you still going with 1 or 3 GPU's and why?
