PSU Wattage for these parts?

I am interested in building a custom gaming rig and I don't know what wattage PSU I'd need. Here's the list below, with links:

Motherboard: Gigabyte P67A-UD3-B3

CPU: Intel i5 2500

Links: (it's a bundle) http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=165454&CatId=6982

Video Card: MSI GeForce GTX 570

Hard Drive: Seagate Barracuda, 1TB

I'd also throw on a CD/DVD drive, maybe Blu-ray, and a media card reader. Any suggestions for brands and wattage needed?

Once you decide wattage including some extra for expansion/room to grow...get a good quality unit ... Corsair is my favorite.

I tried using one of the recommended ones but I couldn't figure some of these things out. Maybe I just need to try a different one.

That said I always recommend having room to spare or grow. Personally I wouldn't use less than a 650W. Here are some good quality units from Corsair.
