How do i find out if my pc is has an ATX case or mobo or whateva?

Hi, simply i need a new PSU around 630w. But ATX ones keep popping up, and I don't know whether my pc is ';ATX'; or not. Anyway to find this out? is ATX the case size?or mobo size?

Its easy! Pop open your case. If you are facing the front of the pc, if it is atx, the side that allows you the most access will be a panel on the left. If its BTX (a lot of new Dells are BTX), then it will open to the right. (Remember, face the front of pc on eye level, or it wont work!
