Letting out the factory supplied smoke is hazardous to your health, it is a violation of various state and federal laws and regulations, including those of the EPA and the "clean air act."
Worse yet, attempting to re-install this smoke is an even MORE serious crime, and is punishable by very large fines and imprisonment.
Even attempting to buy, possess, transport this smoke is illegal. It is extremely toxic, and besides that, it smells bad.
Your power supply is, to use a word, toast.
It is possible that nothing else was damaged, and it also possible that something else WAS damaged.
I think what I'd recommend is this: attempt to get a compatible power supply out of an older machine, a "junker" if you will.
(Radio equipment, for example, comes in different classes. Keepers, shippers, drifters, slappers, droppers, and sinkers. A sinker is a junker before it becomes a sinker. This is also illegal)
Anyhow, pull everything apart, and hook up your "used" PSU ON A TABLE where you can work with the system.
Hook up ONLY the PSU, the motherboard, CPU, RAM, and a video card if not built in
Hook up the keyboard and a monitor.
See if the board will boot and access the bios.
Next, hook up the floppy, and see if the "system" will boot to a known good floppy. A typical Winhoed98 startup floppy is excellant.
Next, hook one of your CDROM's and see if it works--try booting to it, or reading a cd in it with the above floppy disk.
Next, add other drives, ONE AT A TIME, and see if they work.
DO NOT connect or deconnect ANYTHING while the machine is powered on.
If you're satisfied that the thing works, put 'er all together and go order a new supply.
It, too, will come with new smoke installed, just waiting........
