Could you give me the ram you will be using? and also If you dont mind going lower and since your getting a H100i you could always get a 8320 and save the money. An 8350 is just a higher clocked 8320. With the h100i you could easily overclock the 8320 to the same speeds and higher than a 8350.

a 80+ Gold 450w or 80+ silver or bronze 550w will be good enough. get a 550w if overclocking. (ROUGHLY)

fx 8350 under load = 200w
200w+339=539+20w(fans, cpu cooler)=569
mind you get a quality psu like seasonic or xfx

is the 8320 an 8 core because i will be doing video editing and i know more cores are better

Yes 8320 is the same in pretty much every aspect besides clock speeds.

ok do you have any idea the heat a 8320 or 8350 produce at 4.5 gigahertz because i hate heat even over 50 i let my pc cool down

Depends on the voltage you use. Say if you get lucky and can keep it at stock voltages even with the overclock. It should be VERY cool (25-35c) under load. i have the 8320 at 4.1Ghz at stock voltages (Crashed at 4.2 stress testing :( didnt get a good chip this time) And underload max temps i ever see with a 212 evo is 41c idle is about 30-33c So im sure H100i will be alot better since thats a top of the line all in one liquid loop and i have a budget heatsink.
