    Greetings!!

    I own a outdated Dell GXMT 5200 computer. Unfortunately, the power supply went down. It is a Liton (Taiwan) PS-5231-1-1 Rev.4, and the pin layout is as follows:

    Color Signal Pin Pin Signal Color
    Gray /PS_On 11 1 +5V Red
    Black GND 12 2 GND Black
    Black GND 13 3 +5V Red/Black
    Black GND 14 4 GND Black
    White -5V 15 5 Power_Good Orange
    Red +5V 16 6 +5VSB Purple
    Red +5V 17 7 +12V Yellow
    Red +5V 18 8 -12V Blue
    Brown TFSC 19 9 GND Black
    Red +5V 20 10 GND Black

    I am trying to repair it, but I don't know what does TFSC stand for; what is its voltage;
    polarity, and current.

    Any help is appreciated.

    Thank you.

    What is TFSC

    TFSC = thermal fan speed control its the reading for RPMs of the power supply fan.
    All the Dell workstation PS have this function for making sure the PS fan is running.
