I need to replace a PSU on a eMachines etower 400ie. The system runs fine with standard ATX, but its much to large to fit inside the case. I am guessing the original is micro ATX, but have nothing to compare it with.
The dead PSU is a Elcom Power Supply Model: ISP 120S 120W Its 4 7/8" wide, 2.5" tall and 3 7/8" long.
It looks like a 5" long model could be squeezed in if the cdrom was removed first.
It looks like a micro ATX, but I can't there is nothing at emachines website or written on the PSU itself to confirm this guess.
They are only willing to point me toward their $50 145 Watt PSU replacment.
