Computer won\'t turn on. Power supply is okay. Is the motherboard bad?

power supply is working but computer wouldn't turn on, is the motherboard faulty ??

How was power supply tested? installed in another system? Did the fan power up on CPU? Are ALL connections from power supply to components secure? Also check the cable from the computer case power switch to motherboard for connection.

It's the PSU connector, just make such it click when putting it in. I had the same problem. LOL
