I cannot physically prove that you need the extra power with these modern pieces of hardware to run the new systems shy of plopping a 400W PS in my system, showing you the dip in framerate in various games, putting my big PS back in, and showing you the difference, and that isn't happening because it's a hell of a lot of trouble to make a point that those of us who do this for a living know. Hell, they teach this much at the community college to first-year students! I also know that it is taught at larger colleges in the area, such as State. You're entitled to your own beliefs, but this is a cold-hard fact and not believing it shows off both a closed mind and immaturity.
I repair systems every day that are turning off randomly, and the problem is always a crappy PS. My old PS was a 450W ThermalTake with dual fans on it. I'd start playing WoW and after a while the system would hard-lock, or simply power off without shutting down. WoW was the ONLY game doing this, so I blamed it on WoW. Turns out it was the power-supply shutting down to protect itself from too much being drawn. The end-result was that my +12V lead burned up badly and ruined both the PS and the motherboard. So don't tell me that a 450W PS is enough power for a P4/3.20GHz Prescott with an Audigy II and 7800GS. I don't have any other expansion cards in the system and I don't use an USB devices beyond my keyboard and mouse. The simple fact is that 450W was too damn much on the system. I upgraded the PS and can play games like UT3 without a hitch. By your reasoning, I only needed around 200~300W. So explain this magical phenomenon to me, because I supposedly had 150W to spare.

mmmk.... this thread is getting old. <font color="red" font size="3"> Let me set
everyone straight. Anymore arguing this point will result in post deletion. We do not need to fight. </font>
Modern GPU cores are very energy efficient. A 450w PSU is more than enough to run what you are describing, unless you have 4+ HDDs connected with dual ROM drives.
The issue you are describing is faulty amp draw coupled with insufficient rail amp push. Basically, your PSU was low quality or defective from the start.
The power requirements for cards are actually relatively low with the exception of the GTX 280 card, and even then, at full load an 800-900w will power 2 of them. The issue with many PSUs is simply lack of rail amperes, be it on the 12v splits or 3.3v. Usually the 5v is fine, but I have seen cases where it too is low.
Baratus, you are confusing TDP with core draw. Core draw is relatively low on modern graphics cards, especially with DiEC rerouting and zoned powerdown. The requirements for cards are based on stardardized system layouts, with average components in a typical build. Those are not the actual power usages of the cards (especially the core)
And Pentium 4 processors didn't use THAT much power. They simply were inefficient at using said power, and they had terrible DiEC gate leaking, which caused thermal pocketing. The only reason they were able to run so hot without extensive damage was thanks to long pipeline design with extensive cobalt nMOS and COI. P4's are an extinct technology, and were a terrible creation in the first place. So really, that discussion is irrelevant.
Syco, I advise you budget a bit more money, and get this card:

Yes it is a PNY, but the card has been well received and got great marks in our failsafe labs. Not only that, but it is only 30 dollars more than your budget, and worth every penny.
As for power requirements: You need about 24A on the 12v rail, and about a 450watt PSU or better. I would recommend a 500w min, with 26A on the 12v rail. That card screams.
ATi cards, while impressive, draw more power compared to the new 9800GTX+ and 9800GT under most circumstances (in particular under load)
