AMD uses dual channel RAM, you want a 2 x 2GB kit. As for a PSU, you could use pretty much any good quality one because you don't have a discrete GPU. I would recommend the Corsair 400CX http://www.newegg.com/Product/Product.aspx?Item=N82E16817139008

do you know if i can run 2 x 4gb(2x 2gb) if that makes any sense as the mobo says it has 4 slots for memory

You can, but why do you need 8GB of RAM?

The OCZ 400w, the corsair 400w or the antec earthwatts 380 would all be good choices. 2x2 GB RAM should be plenty.
