power-supply

I have recently replaced my old Corsair TX650M PSU with a new CoolerMaster Silent Pro Gold 800w PSU. With the old PSU when I turned off my computer from windows it would shut down and everything would turn off. The lights would turn off and the fans would stop turning. With my new power supply when I shut down windows It shows the usual shutting down dialog then my two monitors say "no signal" and turn off. The weird part however is that the lights stay on and the fans continue spinning forever until I manually hold the power button in for 4 seconds then finally everything shuts off. How can I emulate the previous behavior?
