I would personally burn every peace of dell equipment I own!
Get an Antec SmartPower 2 400W or 450W. I love my 500W one, it has modular cables and it is VERY quiet!

I'm not so sure I would go that far... Dell makes good PC's. sure they can't be OC'd but for 90% of the population Dell is great.

so anywho... I belive that 18a should do it... but it would be cutting things close. the problem is that you may not be able to get just any psu... sometimes Dell uses different connectors rather than the standard ATX power connector so you might not be able to get just any psu. if this is the case then pc power and cooling makes some dell specific psu's

if your mobo has a standard atx connector then you're free to get whatever psu you want. I'd suggest a Seasonic S12 series... the 430 (I think) would be good for your system.

Your will need a new PSU, I would go 450W or higher. 400W or higher will be fine though.

I'm also wondering if I have to upgrade my psu, I'm changing to a 6600gt too. I have a 350w, but it's codegen so I don't know if it will be stable enough. I've decided to just try and see if everything works fine once I get the card, that way I won't be buying something that isn't necassary.

How can it be 350w if it says 250w on it? I don't know much about computers, but I know audio amplifiers are rated in peak and rms watts. Average watt output is what matters. I though the standard rating on psus was the average not peak.

well that's not necessarily true. most cheap psus rate themselves as the peak they can provide for a couple seconds. it's not until you get to quality psus that they rate the rms rating.
PC power and cooling
Seasonic S12
OCZ powerstream
Antec NeoHE
I know all these lines rate their psus' at rms ratings. their peak value is much higher.

I think you'd still be best getting a new psu. Dell may make decent computers but they keep them cheap by getting cheap parts (case, cables, psu, etc) so if the psu says 250w it's probably able to output 200-250w rms and peak at 350w. best case senario you put your new gfx card in and it works just fine. worst case senario you put your new card in and it works for a short while but adds enough stress to your psu that it blows up and takes your rig w/ it.

Is it common for a cheap psu to damage your mobo? I though there were fuses in the psu so if it blows it wouldn't damage any other components.

Dell uses proprietary parts that ONLY work with Dell equipment. That is cheap, plus they get the cheapest parts their dirty little hands can find. DELL SUCKS!
