What size PSU should I get?

[mikemdm100]

I have my whole build ready and I'm about to order but, the last thing I want is to not have enough juice to power this thing.
My parts are:
i5 4670k
Asus Z87 MB
WD Caviar Black 1tb 7200 RPM HDD
120 gb Corsair Neutron GTX SSD
Corsair Vengeance (2x4gb) DDR3 RAM
CM Hyper 212 Evo CPU Fan
CM Haf 932 Advanced Case
EVGA 660 FTW Signature 2 edition.
I don't know whether or not a 500w PSU is enough or I need more.

I have a strict 1000 dollar budget and that puts me over. Is this a good option as well?
