PSU Help for a Build

So to make the story short, I'm going to build a new computer using an old Dell Dimension 2100 Case and I need a power supply...

http://www.power-on.com/dell250x.html

This is a replacement one for the case, but i am looking for a more reliable and higher wattage psu (450-550ish?) I'm not going to use any of the original interior parts.

The case is a micro atx, and the stock psu is roughly 15 *15 *9 mm?

Side note the power supply originally was also used to cool and vent the system

Do you have any suggestions?

If the link is to your current psu then it is like regular atx psu, you might one look at corsair psus depending on your budget and location.

thanks,

thats what i was contemplating going for, but i wasn't sure if they were going to work

plus newegg doesn't have physical measurements of the items

Just follow manufacture's link from newegg to the product.

Here's size for corsair vx unit

150mm(W) x 86mm(H) x 140mm(L)
