Is a 600w PSU enough

[Brynadinaling]

I'm currently purchasing & planning to build a fairly budget gaming PC games such as Far Cry 2 & S.T.A.L.K.E.R Call of Pripyat being the newest games I play.

I'm buying a 2500k i5 that I plan to overclock slightely up to around 3.6/3.8 just for a slight boost to browsing and gaming.
EVGA 550ti GPU
either 8 or 16gb of RAM (corsair vengence low profile)
A large Nohctua NH d14 processor cooler
Fan controller
5 fans
2 Hardrives
perhaps an ssd
blu ray drive and a standard dvd drive
ASUS P8z77 - V LX motherboard.

I know that most i5 prebuilt computers come with
a 400w, and a GTX550ti is a reccomended 400w although its tdp is around 160 I believe. but Is a 600w enough to run all that stably? and underload just in case I do pick up a more modern game (cyberpunk looks cool, and I know Ill need a more powerful graphics card to run it)

Oh and its a Corsair builder series 600W just in case you wanted to know.

600W is more than enough but i would get a modular PSu for better airflow and cable management.

Any quality PSU for Seasonic, Corsair or Antec would be great.

Ah thats no worry, I've a mountain of cable ties, a Full tower case and Ill try to use as many of the leads as I can.

How backwards compatible are these new PSUs?
