GPU upgrade, Requires new PSU

I'm in the need for a new graphics card, and my budget is $100, and I'm looking at Newegg for my site of choice. My computer's detailed specs are here
I am looking at a Radeon 4850, like the one here and I have no idea what PSU will fit in my case, I think the MoBo is a standard mATX, but no idea about the PSU. I think all thats plugged in now are:
2 SATA HDD's
1 PATA DVD Burner
MoBo, which distributes power to the memory card reader, and fans.

I can check more tomorrow, but I don't feel like unplugging and taking apart my computer now.

What should I be looking at for my PSU? It's got to be at least 500-Watt

  1. I like Corsair units, but they are not the cheapest.
  2. How do i know if it fits though?
  3. Unless the case is a micro or desktop unit the chances are good, but if you look up the specs on either the Corsair website or the site where you are going to order from and then measure the one that you already have and compare the numbers if they are the same then it will fit.
  4. it is a desktop unit, in the link for the specs, it shows that its a Gateway GT5658e

    Desktop case = &

    Midi tower (yours)=
    it's not a micro or a desktop and should have a standard sized PSU so measure it to make sure.
  6. oh, ok, and it should have all the right plugs pretty much no matter what, right?
  7. Yep, a Corsair unit will have more than enough plugs and connectors for your needs.
  8. Ok, well I dont have $80 to spend on a PSU. are there any other less expensive brands that will be long lasting and robust?

    There are many other brands and any of them will fit and if they go 'pop' and destroy your rig in the process I do not wish to be looked upon as the person who recommended it to you.
  10. ok, well thank you very much for all your help, I think I can take it from here
