I bought a bunch of PC parts that were validated to work together (by pcpartpicker) and when I try to boot up the PC using the power button from my old case (a prebuilt shitty Gateway) the only thing that has power is the light on the power button. No other components work. I'm 100% sure I have the wattage on the PSU correct, and I've plugged everything in, but still none of the fans start to spin. Thanks in advance.
