[QUOTE="9mmSpliff"]you are probably right on the bubble of 350wt-400wts of usage. You could try it, but you do risk burning your PSU out and maybe running into a problem with the GPU. Here is a mATX PSU for that Gateway . I can not see it using an ATX, but if it did, you have to watch the length. I had a Compaq given to me for free once. I disembled it and stuck it in an aftermarket case with an aftermarket CPU and more RAM. Then I was able to run my ATI X800xl OC off of it. Man that was a while ago. lolMaoTheChimp

Are you certain that the PSU is of mATX form factor? After eyeballing some pics of the internals, I was under the impression that the PSU was standard ATX.

8500GT is pretty low-end. I wouldn't expect to get a whole lot of performance out of it.
