PSU and upgrade

[pickxx]

i am looking to purchase a 6800GT and i doubt the PSU that is in my case now, 300W Antec pure power, is going to be up to the job.
i am looking to upgrade the PSU but i am quite confused. I am looking for something under 90(max) but more around 45-50.
I have a Chaintech VNF3-250, A64 2800+, 1dimm 512 Kingston ram, 1DVD/RW drive, 200GB internal HDD, 80GB External HDD.

Which of these is best, if none are the best for me can i get a link to whats better?
Thanx

Cheaper is better, i am not looking for the best at any cost. But i am not opposed to spending higher for a better value.

Of course Option 5 will probably provide the most power (~460W), but Option 2 and 4 might do (they're about equal in output). I don't know 1 and 3.

If it was for YOU what would you do, would you go overkill and get Option 5 for 20bucks more? or would you go with anything else i have listed or something not listed?
Noise doesn't bother me, but i dont want a jet engine that my music can't cover up.

Tough choice. That FSP350 has the fan controller knob, right? I've found that setting it around 1/2 speed allows it to not kick into thermal override. But the FSP400 certainly looks better considering your card choice.
