The unfortunate thing about powersupply burnout is it is often accompanied by burnout of other components such as motherboard, CPU etc.

Connecting the powersupply is a relatively simple thing. There is a 20/24 pin main connector and only one place on the motherboard it can go.
There is likely to be at least one 4 pin square connector that also goes to motherboard, again only one place to connect it.
Then there are the power connectors to the drives. Most are white 4 pin flat and will only plug in one way. You may have SATA drives and the power connector for those is usually black. Again they can only connect one way to the drive.
If you have a floppy drive there is a floppy power connector that again will only plug in one way. Finally you may have a graphics card that needs it's own power connection.

If you have plugged all those things in and still cannot boot up then something else failed when the powersupply blew.

It sounds like you are a novice at this and would not have a ready supply of spare parts to swap in/out for testing. Time to take it to a tech before spending any more money on components without knowing for sure which ones need replacement.
