Hello guys

I am building my first system. 4770k, Asus Sabertooth z87, gtx 780 and corsair 16gb DDR3 ram.
I wanted to ask what is the difference between:

Corsair AX 850 Gold Certified
http://www.newegg.com/Product/Product.aspx?Item=N82E16817139015

and

HX 850 Gold Certified
http://www.corsair.com/us/power-supply-units/hx-series-power-supply-units/hx-series-hx850-power-supply-850-watt-80-plus-gold-certified-modular-psu.html
And which one is preferable please 

Also, for the case I am stuck between:

Fractal Define R4
http://www.fractal-design.com/?view=product&prod=99

and

Corsair Obsidian 650d
http://www.corsair.com/pc-cases/obsidian-series-pc-case/obsidian-series-650d.html

I really like the look of 650d, don’t mind to pay a bit extra, plus I am ok with the adapter for usb 3. Just wanted to know if 650d is all good for air cooling and silence. Or do I have to go with BitFenix 200mm Spectre PRO Fan and a non standard fan in the back to make it better.

I am not planning on overclocking yet, maybe going SLI in the future and overclocking then. Building a machine for hard earned cash here and wanted to make it cool.

Thanks a bunch guys, much appreciate it!!! :)

Unless you can conform the PCB and VRM design on the EVGA cards, I would avoid them unless its the Classified model.... nice coolers, but Id be concerned about the weak VRM that has historically been used in the SC and other versions in last 2 generations.

id use the Phanteks (5 year warranty, great aesthetics, good acoustics, top thermals)

get the fractal instead of the obsidian. same quality, half the price

the hx 750 or 850 is a great option

as for your build

-do not get a i7 for gaming
-the sabertooth is a total scam. get the z87x-ud3h from gigabyte
-there is no benefit from going from a blue to a black series drive
-the plextor m5s for 169.99 will perform the same in real life
-dont even bother with dominator platinums. they dont perform better yet you pay 2x the price for a few dim lights
-do not bother with blu-ray if you dont watch blu-rays
-id get the phanteks tc12dx instead. cheaper and cools just as well without incompatability issues
-no need for more fans
