newly upgraded pc has no power

First topic message reminder :

i recentlyupgraded my old computer's mobo, RAM, GPU and processor. the problem is, when i tried to boot it the comp is not reacting. there is no power. what could be the problem?

nakabit ko yung 2 power cable (24 pin at 8 pin)
tapos power for hdd at cd
yung board may sarili siyang power botton kaya for the mean time di ko muna kinabit yung switches. speaker lang kinabit ko. pero ganun pa rin result. fan lang ang umiikot.

paki post ng picture, para makita namin kung ano kulang.

replaced ko na mobo ram at cpu. mukhang nasa mobo or cpu yung prob. napagana ko na. kaso may bagong problem.... yung amd data change. update data to dmi...

Try to read your mobos Manual it will help you a lot.... Goodluck!!!
