I am planning on building a new PC but i keep struggling choosing the right PSU. I've read a lot of articles about them but I'm still not sure,maybe you guys could help me out.

The full specs of the future PC are:

-Intel Core i7-6700K 4.0GHz Quad-Core Processor
-Cooler Master Hyper TX3 Evo 43.1 CFM CPU Cooler
-Asus Z170-A ATX LGA1151 Motherboard
-Corsair Vengeance LPX 16GB (2 x 8GB) DDR4-2666 Memory
-Samsung 850 EVO-Series 250GB 2.5" Solid State Drive
-Seagate Barracuda 2TB 3.5" 7200RPM Internal Hard Drive
-MSI Radeon R9 390 8GB Video Card
-Samsung SH-224DB/BEBE DVD/CD Writer

And I'm thinking between 650w and 750w PSU.
Clearly 650w will be enough for my setup,but in case I will add something to it,in the near future(although I don't intend to do that for the next 3-5 years[hope so]) , would 750w be like an 'overkill' ? Would it affect the PSU overtime and my bill a lot?

P.S. Even though I went for the 6700k, I'm thinking if it's worth the extra 72£ instead of the 6700 in my case?

I always get more wattage than I need for the same reason. The efficiency (like Bronze vs gold) will affect the electrical bill not the max wattage. I would only get 6700k if you plan on Overclocking otherwise go for 6700.

This power supply is very efficient but comes at a premium

Ok,it makes sense now. But how about the PSU? Will it suffer overtime or get damaged from all the extra wattage he's not using? (as I've heard some rumours about it)
