2. PS-ON Signal - Wikipedia

   en.wikipedia.org/wiki/PS-ON_Signal

   #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).

3. Power supply unit (computer) - Wikipedia

   en.wikipedia.org/wiki/Power_supply_unit_(computer)

   Entry-Level Power Supply Specification (EPS) is a power supply unit meant for high-power-consumption computers and entry-level servers. Developed by the Server System Infrastructure (SSI) forum, a group of companies including Intel, Dell, Hewlett-Packard and others, that works on server standards, the EPS form factor is a derivative of the ATX ...

4. ATX - Wikipedia

   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.

8. 16-pin 12VHPWR connector - Wikipedia

   en.wikipedia.org/wiki/16-Pin_12vHPWR_connector

   The 16-pin 12VHPWR connector is a standard for connecting graphics processing units (GPUs) to computer power supplies for up to 600 W power delivery. It was introduced in 2022 to supersede the previous 6- and 8-pin power connectors for GPUs. The primary aim was to cater to the increasing power requirements of high-performance GPUs.

9. Power good signal - Wikipedia

   en.wikipedia.org/wiki/Power_good_signal

   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.
