Do I have enough power?

[Dakez0]

So I'm getting a i5-4690k here shortly and I want to make sure I have enough power to run everything, an then OC the i5. I have the Evo 212 cooler to add on, and here's the rest of the list. I was thinking I should be good but it never hurts to double check. Also, I am considering an upgraded PSU so before you add on with that, I know. CX's aren't spectacular.

PCPartpicker List of my build (only difference is it's a Gigabyte r9 290 not the dual XFXs listed. Site doesn't like mixing and matching.

Here is a review suggesting 800w as a minimum and if you plan to overclock I would pass on the cx750 and get an EVGA Supernova 850 G2.
