Will this work?

mobo: Asus rampage IV black edition

Cpu: intel i7 4960x

Gpu: gtx 780ti quad sli

Ram: Corsair dominator platium 1600mhz 64gb

I do know i can get similar perfomace for cheaper but this is what i want so yeah :)

also how big of a psu do i need for this? 

What are you trying to render the universe? 

Am i not allowed to do that? lol

Try a 1500w psu.

Okay... seriously... what are you doing with this computer? I'm guessing we could cut the budget by 3/4 and still give you the same performance from a noticeable standpoint...
