How many watts will my build need?

As a first time PC builder I have no clue how many watts my power supply unit should have. I want to be on the safe side with power.

This is what I am thinking of going with:

Rosewill 550W Gold Certified

This is the rest of my build:

Case: Ultra Defender 2 Black

CPU: Intel i7 4770k

GPU: Asus GTX650 TI-OC 2GB

Motherboard: Asus Z87-A

Thanks!

More about watts build
  1. Good except I'd get ripjaws x 16 gig 2133mhz kit for 164$ rest is good and compatible
  2. http://pcpartpicker.com/part/xfx-power-supply-p1750bbefx
    swap out your for this larger wattage unit it a seasonice unit and it have extra wattage to keep your gaming rig safe.
  3. What do you guys think of the company Thermaltake? I just found this 750W Gold Certified for $75.
    http://www.newegg.com/Product/Product.aspx?Item=N82E16817153170

    Sorry, I probably should have said I am looking at the cost in this. (No more than $100).

    Also, if it makes a differences with how I will be using the build: its half and half for demanding software and gaming. Nothing too crazy with gaming, more on the casual side. And I don't plan on doing too much overclocking.

    the only ref's I get on the video card is 400W or better... I try not to go under 600W for Gaming rigs. no point in building a great system if you heat it up with an under powered PSU...
  5. http://pcpartpicker.com/part/antec-power-supply-hcg620m

    He only has one GPU atm and this 620w is more then enough. Its also made by seasonic and priced really well for this week.
  6. Alright last post, I have to do order one out before the day is over.

    So it's down to these:

    Corsair 600W (non-modular) Bronze-cert
    http://www.newegg.com/Product/Product.aspx?Item=N82E16817139028
    (although I heard the CX series sucks)

    Rosewill 630W non-modular Bronze
    http://www.newegg.com/Product/Product.aspx?Item=N82E16817182200

    Corsair TX650 Bronze cert
    http://www.newegg.com/Product/Product.aspx?Item=N82E16817139020

    the one sportfreak showed me:
    Antec 620W modular bronze cert
    http://www.newegg.com/Product/Product.aspx?Item=N82E16817371059


    Argh there are way too many options, and it only makes it worse that I'm an indecisive person to begin with ha.

    I realize though that some titles say "Haswell Certified" or "Haswell Compatible", do I have to look for this as I'm going to be using the 4770k?
  7. Add this to the list as well:

    Its fully modular and NCIX still has it in stock compare and on sale. Even tho the W is much more then you need its kinda cheap.
