Make and model number of motherboard would help. Is there a separate 4 pin connector?

Have a look click here and download the manual. Scroll down to page 31 for front panel connections, just to double check you have the correct pins. And I assume you have connected the 4 pin connector?

thanks yes those are the pins but nothing happens seems no power to them and yes connected 4 pin checked all voltages with meter and ok

Then sadly I think the motherboard has failed. If you have the opportunity you could try the PSU on a different board, to confirm it works and try the motherboard on a different PSU before discarding either item.
