Help me find a power supply? :D

[SowingGold]

Hey, Hi.
I am a total noob when it comes to knowing what power supply I should get for my computer. Basically I am looking to buy a "DIY Combo" form Newegg (Canada) and this combo does not come with a power supply. So anyone that can help me PLEASE help me, it would be much appreciated.

So here is this combo: http://www.newegg.ca/Product/ComboBundleDetails.aspx?ItemList=Combo.644142

As well as that combo I will buy a graphics card. It will Probably be radeon 5670 or 5770.
Here they are:
5670: http://www.newegg.ca/Product/Product.aspx?Item=N82E16814125360
5770: http://www.newegg.ca/Product/Product.aspx?Item=N82E16814150539

Also any tips with the WHOLE computer would be nice, if I am forgetting anything. I just want a decent gaming build for a cheaper price since I am only 15
I also would not need a cd drive since I can salvage the one from my old computer

This one will work: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139012

It's Corsair, and it's modular!
