Should I get a bigger power supply?

So I was looking over pc parts that I'm going to get and I was wondering if I should get a bigger power supply (I'm not that great with all this pc mumbo jumbo so I have no idea)

The build is here
http://pcpartpicker.com/p/zwtD

Should I get a 750w psu or should I be good with the 550?

Thanks :bounce:

    Hi - realhardtech suggests a 550w unit for a system with
    a gtx680, and there's headroom built into that.
    So, you are good to go the the XFX550. You only
    need more if you plan on SLI in the future.

    There's no harm to your computer in getting more PSU
    power than you need, but it's a higher (unnecessary)
    up front cost. I chose that route myself, needed 450
    got 650.

  4. The most important point in buying a psu is quality. Go with a good brand that stands behind their product and honors their warranty. Check reviews using RealHardTechx.com's review database. Stated wattage means nothing there is no standard using to measure output. You only have the reputation of the brand.

    BTW - The XFX(Seasonic built) you selected is a quality unit:

  6. I looked at you build and I would spend a little more money on the mobo. Look at Z77 mobo and higher end brands like Asus. The 680 deserves it.

    Alright thanks for the help. I'll probably get a 750 just for the extra power in case I do SLI in the future. (It makes it run better correct?) It's not much more expensive so it's better to probably get that :P

    Edit: New PSU: Antec HCG-750

    Good choice - I did something similar needed 450-500w
    and got a 650.
