Power requirements/PSU suggestion

I will be attempting my first bid very soon. I am unsure what my power requirements will be. I used an online calculator but the number it gave me seemed very low. I am looking for advice from those who are more experienced. If I have made any poor component choices feel free to let me know as well.

Here is my parts list:

AMD Phenom II X4 965 Black Edition Deneb 3.4GHz
2 x MSI R5770 Hawk Radeon HD 5770 1GB
G.SKILL Ripjaws Series 8GB (4 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600
Western Digital Caviar Black WD5001AALS 500GB 7200 RPM
CORSAIR Cooling Hydro Series CWCH50

I would like to have sufficient power to overclock several components and add a second hard drive in the future. I am really stretching my budget as it is so I am looking for the least expensive option which will work well.

What Wattage should I be looking for? Any specific recommendations?

Thanks For Your Time,

Here are the official ATI power supply requirements for the ATI Radeon HD 5770 and 5750 video cards:

450 Watt or greater power supply with one 75 watt, 6-pin PCI Express® power connector recommended

600 Watt or greater power supply with two 75 watt, 6-pin PCI Express® power connectors for ATI CrossFireX™ technology in dual mode

The recommendations are for an entire pc system.

Corsair and Seasonic are two brands that have a reputation for high quality power supplies that consistently earn high marks in technical reviews. They are reliable, stable, and come with a 5 year warranty. Some of the newer models come with a 7 year warranty.
