What graphics card can I install?

[Djlast]

Hi everyone, i need your help figuring out what card I can fit in my crappy Dell without having to upgrade the PSU or mobo. Below are the PC's stats from a dell site scan, and the PSU is a 300 watt unit from the factory. I'm am new at this so I don't know if this PSU has the right connectors for a modern graphics card (everything is SATA, in case that makes a difference). I was hoping to use a Radeon 4770 or 4870 but the more I read, the less like it seems that anything that advanced will work on my PC. Any suggestions? I appreciate any tips, thanks!

Your best option is probably a ATI 4650 or 4670. NO WAY can you run a ATI 4770 or 4850/4870 without upgrading PSU.
