So I have been trying to set up a new computer and am getting very strange problems with it. I have tried three different power supplies to power this thing, which makes me think that I do have enough power. The system has an asus a8n sli deluxe mobo, x1900xtx, 2 gigs of ram, and an amd 3500+. Now heres the weird part:

I can get all the fans to turn on when I plug in just the 24 prong (or 20 prong, because one of the power supplies only has that, and the ez plug) and the video card power input. I am fairly sure that it doesn't turn on when I don't plug the video card in. (is that normal?.. not really my main problem though). Yet, even though the fans are all running, I get two little red led lights light up on the video card, which I am fairly certain means the video card is not receiving enough power, which makes sense.

Now, when I plug in the four prong connection, and power on the board, I can't even get the green LED light. It seems like in order to even have a shot giving the computer enough power, I will have to plug this four pronged chord in, but it just won't work when I do.

Thats really all the info I've got right now.. Please could anybody shed some light on the situation? I'm out right now but I am going to swap out of a few of the pieces and see if the ram or something is the problem.

Thanks
