at -atx whats the difference?

[Mykex]

The Atx has one large connector going to the motherboard 18 pin I think. The on off is controlled by a switching system that runs through the mobo. AT has a few smaller connetors and the on off is controlled by a switch that runs directly from the power supply.

BTW some PC makers use proprietary PSU's so they make look somewhat like AT but are really ATX ....ran into this with a Compaq so just an FYI

ATX m/boards have soft power control, rather than a "hard" switch. They also have all the I/O ports(parallel, serial, usb, etc) fixed to the board. Therefore they require an ATX case, with the appropriate rear panel to accomodate these ports.
