I just built a brand new pc and when turn on the power supply the led's on the motherboard come on and when I press the power button on the case the fans activate for 1 second then the pc just stops and shuts down. The psu 24 pin power connector isn't fully in and hasn't clipped but I'm not sure if this is the problem, I have pushed the cable as hard as possible but it just wont go and further. I have rearranged the connectors on the F_panel but that has done nothing and they are all in the correct place. And response would be appreciated

Does your motherboard had it's bios updates?
Just so you know ALL b350 motherboards with out Bios Update can't boot/start with the new Ryzen CPU..
This is the only problem that you may have...
Because many people had the same problem..
If you did your bios update then the HDD may be defective..
