ATX\Micro ATX power

[Yo-Yo]

I am doing a lot of upgrades to my system for graphics purposes and my current psu isn't enough for the graphics card. I have a micro atx system and I would like to know if a normal atx power supply will fit or if it will be too big?

I pretty sure it would be too big, you can take it out and measure it's dimensions and go from there though too

I managed to shoehorn a standard ATX supply into my tiny mATX eMachines box. I got a lot of excess wires hanging around (PCI-E, SATA) that I can't use, but it went in without a hitch.
Take a look here, about halfway down the page: http://www.directron.com/psu.html
There you'll see physical dimensions of the various types of PSU's. Measure yours, and compare it to an ATX unit.
