Would my customized gaming computer need more than 750W Power Supply?

I'm at my last part of picking parts for my new computer, and it's the Power Supply, i gotta ask you folks if these parts i've chosen would need more than 750W, i'm still new to building computers, and this is my first time.

MSI Z87-G45 Gaming, Socket-1150
Intel Core i7-4770K Processor
Corsair Vengeance DDR3 1600MHz 8GB CL9
MSI GeForce GTX 770 Gaming 2GB PhysX
Seagate NAS HDD 3TB SATA3.0

Would these computer specs need over 750W?
Tell me if there is any more information/specs i can add if i missed some :)

  1. No. It probably doesn't need even 500 watts.
  2. As longs as its decent quality it will be more than enough for that config with overclockin, but if you want to add a 2nd gtx 770 and overclock I would suggest 850w. What make and model of PSU are you considering?
  3. I meant 600 watts, oops! And still, 500 could probably work anyway, lol.

    It will not need more than 750W, even when overclocked. Here are very good 750W PSUs. Also, I would get a 840 Pro SSD (http://www.newegg.com/Product/Product.aspx?Item=N82E16820147192) A good 650W PSU will do fine too.

    I didn't really want to choose an SSD because Steam games cannot be separated in 2 Hard Disks
    So instead i added 2TB HDD over buying the SSD.

    But anyways, i do not understand overclocking or what they do, i will probably not overclock whatever i can overclock on my computer as its my first time.

    Well my problem was solved, it doesn't even need 600 watts!
    I'll go grab myself a 650W Power Supply for safety reasons, and also,
    how do you calculate/find out how much watts i needed?
    It'd be really helpful for me in the future!

    It really depends on the draw of the CPU+GPU. You should have at least a 100W to spare in case of spikes. This is a good 650W: http://www.newegg.com/Product/Product.aspx?Item=N82E16817151088 also consider the 750W PSUs linked in my previous post. Try this http://www.overclock.net/t/853462/ssd-owners-must-have-app Anyways, get this CPU cooler due to Haswell's high temperatures http://www.newegg.com/Product/Product.aspx?Item=N82E16835103099
