I recently started building a pc and bought all of my components through pc part picker. Everything is hooked up and I have everything thing that can be plugged in plugged in (atleast I think I do). But when i try to turn on the computer nothing happens its like the button is just being pressed with nothing plugged in. I have the cases power cords plugged into the motherboard with the positive and negative charges in the right places. My leftover cables are some 4 pins, some sata cables, a pci-e cable, and two tkg cables (one from the psu, and one from the case)
