I've got an IBM Aptiva E26 sitting on my bench with what appears to be an ATX power supply, but with AT connectors to the motherboard. The power switch goes to the motherboard. And in the case, a label reads IDATX, so I am pretty sure it's ATX, but I haven't seen one with the AT connectors before. Without going to IBM, which would be a joke, does anyone have some light on this subject. I do have to replace the board so I need to get a compatible one.

Thanks,

Charlie
