PSU+Memory for new system

[mack]

I posted not too long ago about my new system. It's AMD x2 4400+, eVGA Nvidia 7800GTCO, and Asus A8N-32.

I have a FSP Group Forton 500WATT PSU. It's great, and I love it. But here's my question. IS 500Watt strong enough for my new system? I was thinking of:
http://www.newegg.com/Product/Product.asp?Item=N82E16817103931
It's a bit cheaper.

Reason why I'm getting a new PSU is because I'm selling my old PC with the PSU.

My next question is, has anyone ever ordered with ZipZoomFly? If so, what was your experience like? I found this, http://www.zipzoomfly.com/jsp/ProductDetail.jsp?ProductCode=247022
for $20 cheaper, with free 2nd day shipping.

I'm stuck on the memory part of my new PC now. I'm not sure about the type of memory I need, the latencys, or anything. I want to keep it under $200, as I do infact have a limit to stay within =). Here is the memory I'm thinking:
http://www.newegg.com/Product/Product.asp?Item=N82E16820145575
or more:
http://www.newegg.com/Product/Product.asp?Item=N82E16820145574 (this is recommended for A8N32)
According to:
http://compatible.corsairmemory.com...model=A8N32-SLI+DELUXE&model=A8N32-SLI+DELUXE

Here is what I got so far:

http://www.newegg.com/product/product.asp?item=N82E16819103546

I already ordered the case.

Thanks

Im pretty sure that 500 watt fortron is good enough.

ZipZoomFly is a very good site to buy from.

This is the best $200 RAM. http://www.newegg.com/Product/Product.asp?Item=N82E16820231032

Ok, as you can see I'm looking for top-notch components. I never heard of g.skill.

The timings are decent (I think): 2-3-2-5, while the Corsair is a bit higher: 2-3-3-6

Any other opinions?
