Hello :) 

I'm buying a new PC, and I'm unsure how much power supply watt do I need?

My rig:

Cooler Master HAF X Big Tower Sort ( case )

Intel Core i7-4770K Processor ( cpu )

MSI Z87-G45 Gaming, Socket-1150 ( mobo )

Crucial DDR3 BallistiX Sport 16GB KIT ( ram )

ZOTAC GeForce GTX 780 3GB PhysX CUDA ( gpu )

Samsung Syncmaster P2450 ( monitor )

Kingston HyperX 3K SSD 120GB 2.5" ( ssd disc )

And do my stuff work well together do you think ? :)

For a system using a single GeForce GTX 780 graphics card NVIDIA specifies a minimum of a 600 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 42 Amps or greater and that has at least one 6-pin and one 8-pin PCI Express supplementary power connectors.

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

Thanks. I will not overclock anything. Could you recommend a specific power supply?

What is your budget amount for the power supply unit? Do you want a PSU with semi-modular or full modular output cables?

Is 200-300$ enough to get a good psu for those components? I'm not sure what semi-modular and full modular output cables is, does it mean how many cables do I need? I don't need so much I think, because I'm not going to have so many hard drives or hard discs. Maybe 2 SSD's and 1 DVD-drive and maybe later on a Blu-Ray drive.

Modular output cables mean that you only connect up the power cables that you need for the devices you have installed in the computer. This means that you won't end up with a lot of unused cable clutter that you would need to find a place to hide when using a full wired PSU.

''What do you mean " gold rated " ? Sorry''

The increasing availability of higher efficiency power supplies at lower price points has been a gift for silence enthusiasts. Higher efficiency means less waste heat and the promise of quieter fan profiles, passive PSUs that aren't baking at operational loads, and semi-passive designs bringing the best of both worlds. Now, PC builders need to decide how much more they are willing to pay for incrementally higher efficiencies, and how best to compare power supplies with different rated loads.

The good news is that power supplies with better 80 Plus ratings really do deliver what they claim — there is a net reduction in total power consumption. If you burn a lot of power,
could be good investments and pay back their premiums in a year or two. Similarly, if you’re trying to minimize every last watt of consumption, this is one way to do it.
a good efficiency will still pay back its initial up-front cost in a year or two.

After surfing on it a bit I think maybe this 760W?
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Because perhaps in a year or two I will buy another GTX 780 and then I don't have enough PSU if I have 650W ?
I saw that this one has platinum 80 plus. Do you think it would be a good idea to buy this one, or does it really not fit in with this build ?

I know I'm asking a lot of questions, but I want this build to be perfect for me.

For a system using two GeForce GTX 780 graphics cards in 2-way SLI mode NVIDIA specifies a minimum of a 850 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 65 Amps or greater and that has at least two 6-pin and two 8-pin PCI Express supplementary power connectors.

If any overclocking of the CPU and/or GPUs is going to be performed I would recommend that you go with an 850 or 860 Watt PSU.
