To add some ideas to those other good ones: do those fans operate
on the -12 volts? IOW the fan's red lead would connect to where other
black wires connect. Using a meter to read voltages (and polarity)
would have gone a long way in avoiding such oversights.

Second, does the power supply refuse to tell power supply controller
that it is OK when it does not see fan sensor? This again requires
using a meter to read voltages on purple, green and gray wire (power
supply to motherboard) both before and when power switch is pressed.
Providing those numbers here would avoid assumptions that we must make
in every reply.

Power supply controller tells power supply to power on. Controller
then waits for an OK signal from power supply. If that signal does
not happen, then power supply is turned off. If your supply needs a
sensor signal from the fan, then would it declare itself OK? A
question best answered if you collect voltage numbers both before and
when power switch is pressed with a meter.

Two ideas to eliminate assumptions that create confusion.
