Usually there is only 1 PSU - unless you are running bigger servers. The PSU has multiple connections and multiple voltages to run different things - for example 12V for your drives and 5v for the CPU etc. You can have power to one thing without the other. I discovered on the old AT supplies that if the blue wire was damaged the computer would run perfectly but the serial ports wouldn't work!!!
