Is radeon hd 4350 compatible with dell inspiron 530s

That's a negative. You'll get a crashy system most likely. 250Watts is only barely enough for onboard video.

you have no clue to what you are talking about, please don't reply to posters.

I have two 4350 running on that exact same PSU and have been for well over a year without a single issue. The ATI 4350 hardly draws any power, you can run it with two gerbils on an exercise wheel.

For the Radeon 43xx series:
300 Watt or greater power supply (350 Watt for ATI CrossFireX™ technology in dual mode) is recommended

Judging from the poster above, it would look like its possible. But you never know. I would suggest just playing it safe and going with a 300+ watt PSU

its a good thing you guys don't post on the Power Supply Board

here is break down of total power used with an OC i-7 CPU. The ATI 5450 uses the same power as the 4350. At peak the system doesn't break 175w. Even with a 4650 ( acard that uses 2x the 4350 power) the system barely breaks 200w at peak.
