Question about Power Supplies

[LoungeAct404]

what I have right now (at least I'm pretty sure) is a 350w PSU that came with my cheap case from NewEgg. I doubt that it will support a 6800 (non Ultra/non GT), so I'd like to know what would be a good Power Supply that I won't have to pay an arm and a leg for that will be able to support this upgrade. Also, I'll probably be upgrading in the future as well (CPU and whatnot), and I don't know if I need to have a high amount of watts for an upgraded CPU.

Thanks for reading this, I appreciate it.

EDIT:

Would a Fortron 400w be able to support my rig? I see a good looking one on the forums for 35$, someone please let me know.

DOUBLE EDIT:

forgot to mention that my setup is:
2800 barton athlon xp
1gb corsair value
120gb hard drive
vid card is going to be a 6800 regular (VGA)
cd burner and dvd burner

would a Fortron 400w be able to support all that?

If the "cheap case" was an Antec, it should be fine. If not, this.

Depends on what else you've got in that system. A QUALITY 350W and over will power it, but you'd best be off with at least a quality 400W PSU.
Maybe a Fortron, XClio, Enermax, Antec or Seasonic.

go with a antec 420( or is it 430?). This will give you that upgrade possibility

aright thanks for your posts, and no it wasn't Antec :|

The rest of my computer= AMD Athlon XP 2800+ Barton, 512MB RAM (soon to be 1GB of Corsair), 120GB Maxtor, 9600 Pro (soon to be 6800 )
