Is this Power Supply large enough?
For christmas this year, I received a SeaSonic 550 watt power supply, as well as an EVGA GTX 670 Graphics Card, both for my new build. I am planning to purchase an ASRock Z77 Extreme 4 Motherboard and an Intel Core i5-3570k CPU. Should this PSU be enough?

You'll be fine.
A 550W from Seasonic better than a 650W off-brand PSU. What matters most is the number of amps supported on the +12V rail(s).
While 650W gives you room to expand (and allows for PSU capacity dropping with age), that one should be fine for 3-4 years.

Its fine. But I recommend you get a PSU of atleast 650 watts. I have an AMD HD 7870 and a PSU of 650 watts. PSUs tend to loose strength after quite sometime. If you plan on overclocking anything or adding another GPU a 650 or 700 watt PSU is the safest for you.
Get a Corsair or Cooler Master or SeaSonic don't buy untrusted brands.

The minimum recommended is 500 watts for that particular gfx card. I would try to return that one and get something with at least 750 w or higher because power supplies generally will not be able to handle operating at their max wattage for very long before burning out. It is nice to have lots of headroom with your power supply and really you cannot have to many extra watts as the power supply will only supply what is being asked of it.
