Dell 755 optiplex

Hey folks,

Some advise really, I have a 755 which has a psu 280. I'm looking to get a LP graphic card and im really stuck.

I was looking at getting the Zotac GEforce 9600gt eco edition. Specs for this says min power supply 300.

From what I have read Dell's psu are somewhat underrated. Besides I have taken the floppy out and considering taking the cd rom drive out to and using my external dvd writer.

Would i be fine with this and do you nkow if this card will fit, I know it says its low profile, Ihave also read that its not.

Or any other suggestions for a graphics card similar in comparison to the 9600gt.

thanks
