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 EdpNo=7829714&SRCCODE=WEBGOOPA&cm_mmc_o=mH4CjC7BBTkwCjCV1-CjCE&gclid=CKeo4K-HprsCFcxAMgod4GkArg

CPU: Intel i7 4770k

GPU: Asus GTX650 TI-OC 2GB

Motherboard: Asus Z87-A

RAM: 16GB total, 8GB sticks at a time

SSD: Samsung 840 Evo

(any other comments on my build would be greatly appreciated :D )

  1. Good except I'd get ripjaws x 16 gig 2133mhz kit for 164$ rest is good and compatible
    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.

    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...

    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
    (although I heard the CX series sucks)

    Rosewill 630W non-modular Bronze

    Corsair TX650 Bronze cert

    the one sportfreak showed me:
    Antec 620W modular bronze cert

    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.
