Ok, so I bought a pc from a guy here. It came with an m2-atx, and the 1200 mobo. I'm trying to test all this out. the m2 didn't come with the power adapter for the wall, so i decided to bypass it for now, and just test the mobo to get it all formatted and neat with all my programs on it. So I go up to my computer room, and grab an old atx power supply from a tower. Now, that PS doesn't have any switches on it, all it has is a little green light that tells me that it has power from the wall. I just took this PS and had it tested, and it is fully funtional. well, I then plug it into the wall, and then into the atx connector on my 1200 mobo, and nothing happens. ok...

so I look for a place for a connector to put a switch on it, and I just cannot find one. I also noticed that the m2-atx has a connector for a mobo on/off switch. how in the world do I boot this mother board for testing

I have read the manual from VIA and all it tells me how to do is plug the connector into the board (no use to me).
