If you unplug the ATX power supply from the board does it remain on?
All the switch on the board does is ground the POWER_ON pin on your ATX supply to tell it when to turn on. If the power supply is on when not plugged into the board, the issue is in the power supply.
Try unplugging the ATX connector from the board and connecting an ohm meter between pin 16 and one of the grounds and see if you get continuity only when the switch is in the on position. If you're seeing continuity all the time, you either have a faulty switch or there's a short somewhere in your board that grounds pin 16.
