How many watts does my build need?

[FlimsyElephant]

The parts I have are:
CPU- i5 3570
RAM- 2x4GB DDR3-1600 ram
MOBO- Gigabyte GA-z77x-UD5H ATX LGA1155
HDD- Wstern Digital Caviar Blue 1TB 3.5" 7200RPM
SSD- Samsung 840 series 120GB 2.5"
Video card- His Radeon HD 2GB 7850
Case- Rosewill Thor v2

I was wondering if you guys could tell me the amount of Wattage I would need to run this build. I have tried doing the watt calculators online but I don't think I fill them out right. If you guys could help me with this it would be much appreciated.

A 550W should cover you for that build, though if you want to dual Crossfire/SLI later on then a 750W would be a better choice.

Thank you so much. I was really worried that i would end up getting a PSU that wouldn't be able to power my build. Once again thank you.
