PSU = FSP 400-60MDN (12v - 20A I think)
Q6600 2 Quad CPU
3.00GB ram (4 sticks)
8600GT current GPU (came with machine installed)
1 x DVD rom

I wanna upgrade to GTS450 but can I without purchasing new PSU?
I not after amazing graphics, I don't play intensive games just MMOs but they are getting higher requirements now (my existing set-up runs starcraft nicely already) but it is getting rather noisy
I was originaly looking at GTS250 but that states 450W PSU and anything lower does not seem such a big upgrade in performance (I use the sites hierachy charts to judge performance, great ref i think)
The GTS 450 says min requirements 400w 12V and current 22A which is close (ish) to my 20A so u think I could use it with my set-up?
Reading sooo many forum messages and that guides for ratings needed are over protective maybe it would work but thats why am asking on here
I could get a new PSU but am not that keen if i can help it, I yearn for the days when swapping GPU was just pull out card put in new card job done

If you say no please recommend Nvidia card, can't be doin with ATI just sooo many years of hurt with them on families comps

the FSP 400-60MDN has 20a on the 12v1 and 16a on the 12v2. roughly 29a on the 12v rail (you don't add the two splits together). you will be fine
