What PSU would best work for my computer?

Hello, I have a slight problem with my computer at the moment. Buying a prebuilt computer so it would be a bit easier not needing to install some of the things just to find out the PSU is only 250w. I want to add an HD radeon 6670 into it, and an AMD Athlon ll x3 3.3ghz into the computer. (Will upgrade both later.) First, I'm not sure if they could even run on 250w so to be safe, I was wondering what PSU would best work and fit in my computer.

It's an Asus essentio, looks like this:

  1. Looks like a standard ATX psu build to me.
    A cheap Corsair CX430V2 would be fine.

  2. Ive upgraded my grandsons Compaq AthlonII x2 to a Phenon II x3 720 with a HD5670 all with a 230w PSU; give it a try. The 6670 does not require external power and the x3 is only 30w more. You should be at around 150w total under heavy gpu/system load.

    Thanks a lot for that suggestion, I knew they were low profile and all...but didn't know it was that low! Thanks, when I receive the last bit I'll test it out.
