Hello, I am planning on building a new desktop and need some advice as to the PSU I need. so far its looking like this;

CPU: 4790K
Motherboard: Asus Z97 Hero or MSI Gaming 7 (possibly bump up to the MSI Gaming 9 or Asus z97 Maximus Formula if it gets released soon?)
Ram: 4x8gb Corsair Vengeance 1866
GPU: Nvidia GTX 780 (with the plan to add another in SLI around the holidays)
Cooling: NZXT Kraken X60, case also has 3 fans.
Storage: 1 SSD, 1HDD

That's the plan so far, just haven't a clue on a PSU.

Where are you buying from, Redcoat17?

As an aside, looking at your component choices, your motherboard choice seems a bit overkill. There are much less expensive SLI boards that are also decent overclockers, than the Z97 Hero. Do you really need 32GB of RAM as well?

Seasonic Platinum 760W or 860W if you're a 'headroom' type of guy. A rig like that deserves nothing less.

I would be looking to purchase from Newegg mostly. The goal is to make this a overclocking gaming rig. I am starting off with 16gb ram (2x8gb) but with the idea of expanding down the line. I would like this to be a system to last me a good few years, with the odd upgrade here and there.

860 watts would be enough with some headroom for two 780's + overclocking?
I tried a couple of online power consumption calculators but the results seemed all over the place, I think i remember one of them telling me the two gtx 780's in SLI would draw over 600w on max load!

(sorry for delay in response!)

Well, heavy overclocking on both cpu and gpu's could make 760W sweat. I stil think 860W would be enough but if you want to be absolutely sure get 1000W.

Calculators give nothing but a very rough estimate. Better to look at reviews (and keep in mind gaming loads are not as intensive as something like prime95 on cpu + furmark on gpu's).

Thank you for the advice, everyone's input is much appreciated. Nothing less than 860W, maybe I can find a nice 1000W Seasonic on sale or something once I purchase everything.
