Will a 550w PSU run this

[Phy]

i5-3570k
ASRock z77 extreme3
EVGA GTX 660 FTW

I don't have the PSU specifics on hand, but need to know if I really need a bigger PSU.

Side question, is there a better GPU for roughly the same price?

A 550 watt model from a reputable brand? Probably. A cheap 550 watt model? Heck no. Would need to know what brand and model of unit we are talking about.

Myself, I would go for a HD 7870 GHZ over a GTX 660 FTW

To the question, it will be able to if you get a reliable brand.

Opinions, but I personally will never but amd again. But if all you do is game, they hold their own. Anything other than gaming, get nvidia. Their drivers handle extra gaming activities better than amd.

Need to know the specific PSU model to answer this question.
