You're missing quite a bit of info on this one. Did this a prebuilt machine?

Get the Seasonic PSU.

For your budget, I would only get a 60 Gb SSD. Mushkin Chronos or Crucial m4 SSD.

Just get 1600 MHz RAM.

To save you some money, you can get a 500 Gb HDD instead. I think that build, with my recommendations, will be about 1100 max here in North America.
