Most power supply fans are not connected to the speed sensor on the motherboard and so cannot be monitored, but some high-end PSUs can provide digital control and monitoring, which requires a connection to the fan-speed sensor or USB port on the motherboard.
#PS_ON pin is marked by number 16. PS-ON Signal is a pin on a 20-pin or 24-pin ATX-specified power connector used to turn a personal computer power supply unit on/off. The PS_ON pin is normally pulled high in an open-circuit, but will turn on the power supply when it is pulled low, by shorting it to the common signal (COM).
PS_ON# (power on) is a signal from the motherboard to the power supply. When the line is connected to ground (by the motherboard), the power supply turns on. It is internally pulled up to +5 V inside the power supply. [3] [19] PWR_OK ("power good") is an output from the power supply that indicates that its output has stabilized and is ready for ...
The power supply was instead turned on and off via a mechanical switch that disconnected mains power. Modern, ATX supplies, by contrast, are capable of being switched on and off by the computer itself, and the power button is actually a signal that is received by the motherboard and in turn passed along to the power supply.
The ATX specification defines the Power-Good signal as a +5-volt (V) signal generated in the power supply when it has passed its internal self-tests and the outputs have stabilized. This normally takes between 0.1 and 0.5 seconds after the power supply is switched on.
Power connectors, which receive electrical power from the computer power supply and distribute it to the CPU, chipset, main memory, and expansion cards. As of 2007 [update] , some graphics cards (e.g. GeForce 8 and Radeon R600 ) require more power than the motherboard can provide, and thus dedicated connectors have been introduced to attach ...
The power connector on the 3½-inch floppy drive, informally known as "the Berg connector", is 2.50 mm pitch (distance from center to center of pins). The power cable from the ATX power supply consists of 20 AWG wire to a 4-pin female connector. [ 1 ]
A SCSI connector (/ ˈ s k ʌ z i / SKUZ-ee) is used to connect computer parts that communicate with each other via the SCSI standard. Generally, two connectors, designated male and female, plug together to form a connection which allows two components, such as a computer and a disk drive, to communicate with each other.
