i have the NZXT S340 Elite tempered glass case, i7-6700k, Asus Tuf z370 plus gaming mobo, two sticks of DDR4, and a 735W PSU. I have put everything together but it wont boot the fans only spin for a second and stop, the light for the power button briefly turns on as well. There is no boot and I have tried connecting the 8 pin differently with no avail as well as tried a different PSU and I don't know what to do please help this is my first build
