Wanted to know if this system build would work well

Solution


That PSU can deliver almost its entire wattage to the 12V rail. Wattage is not an issue.

Why not just get a single Titan X (Pascal) instead of two GTX 1080s?

I don't recommend SLI for multiple reasons:
1) Support. Not all games support multiple GPUs. Many will only use a single GPU even when multiple are readily available. This issue also applies to dual GPU...
Any reason why you would not go with i7-7700k?
Also you might want to consider waiting a bit for the 1080ti's to come out or at least AMD to deliver some more competition. Both should affect prices.
 


I will be buying all these parts later this year so the price can go down,
so with the i7-7700k will this build work fine, my main issues is the PSU not being enough

I don't recommend SLI for multiple reasons:
1) Support. Not all games support multiple GPUs. Many will only use a single GPU even when multiple are readily available. This issue also applies to dual GPU cards.
2) Power consumption, heat output and noise. The cards you've chosen have open shroud coolers. The air from the bottom card will force the fans on the top card to run faster (and louder) because it'll be saturated in heat from the lower card.
3) Non-linear scaling. Having two graphics cards doesn't guarantee 2x performance. Well optimized games may get you around 180% performance of a single card, while many less optimized games will get you less than 150% performance while still making both cards run at full capacity.
4) Microstutter. This is less prevalent with High Bandwidth SLI bridges, but is still an issue. Basically, it means that having a high FPS doesn't necessarily mean that the game will play smoothly when the second card is in use. There may be stutters, often at points of high FPS and/or low CPU usage.
