Can i get a Radeon 4850 for my dell inpisron 530 350W PSU?

as the looks of it,it has 512 mb onboard memory,people says its a descent card but the question is whats the rest of the hardware,you know your PSU has to run the rest also.I believe there is nothing high end on your pc since this is the upgrade you want,what maeby you have 1-2 gb ram,80-120 gb hard 7500 rpm, and most likely some single core CPU (maeby pentium 4?),yes I believe you can run the card but with 350W you aint going to get the best of it,not just the GPU,the rest of your hardware will lack of feeding juice.Try looking on google whats the power supply requirements for this card,but do not forget the rest of your hardware needs too.
