OP, you are telling "ATI" that you have a 150w psu.

Idk how many times I have to spell it out, but you do not have a 150w psu. The manufacturer used a different rating system to get that number. By today's standards, it is 48w, but it is also old as hell, which means you should keep it under 80% load at all times due to capacitor aging. That means it is not safe over 40w if you want it to last.
Now the CPU alone uses 27.2w. I would expect the chipset and other motherboard components to use somewhere around 5-10w. That leaves you with virtually nothing. Once you add the tdp of your video card (about 20w from my estimation) then you are over both the tdp I would recommend, and the tdp listed as max on the power supply itself. It will ripple extremely bad, shortening the life of components. It will also kill the psu very quickly. I give it 6 months, One year tops before that thing craps out. When it craps out, I give your pc a 40% chance of surviving, and even that is being generous.
Just save a bit of money and buy something with a P4 and pci express. You might as well take your money and burn it if you really intend to upgrade the psu and put a geforce fx in this thing.
Edit: GAHHH!!!! How many times must you ask the same question if you are just going to ignore everyone's responses?

Look, either accept what we are saying, or don't. Just ignoring it is going to get you absolutely nowhere. I have a feeling that most members here are trying to be patient with you, but you are making that impossible. Please read other people's posts, and take our responses into consideration.
Btw, If you want a proper answer to if your graphics card will run on your psu, post ONLY the psu specs, in text form, with no mention of '150 watts' anywhere. Your answer will be quite different. I can almost guaruntee you that people just saw '150w' and assumed that was on the +12v rail, without checking the picture of the label you posted for the amperage.
So I'm outta here. If you don't wanna believe me, it's your money and your computer.
