Having second thoughts on PSU wattage - will it power this build?

Hi guys, I'm wondering whether an OCZ Fatality 550W PSU will be enough to power this build, any input would be greatly appreciated!!

MOBO: Gigabyte GA-Z68X-UD3H-B3
http://www.gigabyte.com/products/product-page.aspx?pid=3853#ov

CPU: Intel i5 2500k (oc'ed)

CPU FAN: Coolermaster Hyper 212

GPU: Gigabyte HD Radeon 6850 1GB 256-bit

HDD: Samsung Spinpoint F3 1TB

RAM: Kingston HyperX 2133mhz 2x4GB

And two 120mm case fans.

Here's the PSU:

    I've got the same PSU and it's fine for me. Since it's out of stock at newegg though I'd go with this one:

    If you double your GPU's you'll need it.
  2. I would consider going for a good 80+ 620w+ PSU, especially if you're planning on expanding your build. Also remember to leave yourself some headroom in the wattage department.
