2. ATX - Wikipedia

   en.wikipedia.org/wiki/ATX

   An ATX power supply provides a number of peripheral power connectors and (in modern systems) two connectors for the motherboard: an 8-pin (or 4+4-pin) auxiliary connector providing additional power to the CPU and a main 24-pin power supply connector, an extension of the original 20-pin version. 20-pin Molex 39-29-9202 at the motherboard. 20-pin ...

3. Power supply unit (computer) - Wikipedia

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

   12V only power connector (labelled P1, though it is not compatible with the ATX 20 or 24 pin connector): This is a 10 or 16-pin Molex connector supplying the motherboard with three or six 12 V lines with common returns, a 'supply OK' signal, a 'PSU ON' signal and a 12 or 11 V auxiliary supply. One pin is left unused.

4. 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).

5. Motherboard form factor - Wikipedia

   en.wikipedia.org/wiki/Motherboard_form_factor

   A 20 % shorter variant of the ATX form factor. Compatible with most ATX cases, but has fewer slots than ATX, for a smaller power supply unit. Very popular for desktop and small form factor computers as of 2017. Mini-ATX: AOpen: 2005 150 × 150 mm (5.9 × 5.9 in) Mini-ATX is considerably smaller than Micro-ATX.

6. Power good signal - Wikipedia

   en.wikipedia.org/wiki/Power_good_signal

   The ATX specification requires that the power-good signal ("PWR_OK") go high no sooner than 100 ms after the power rails have stabilized, and remain high for 16 ms after loss of AC power, and fall (to less than 0.4 V) at least 1 ms before the power rails fall out of specification (to 95% of their nominal value).

7. AT (form factor) - Wikipedia

   en.wikipedia.org/wiki/AT_(form_factor)

   Baby AT motherboard An ATX Form Card, used by later Baby-AT motherboards to allow for USB, PS/2 mouse, and IR connectivity through headers. In 1987, the Baby AT form factor was introduced, based on the motherboard found in the IBM PC/XT 286 (5162) [2] and soon after all computer makers abandoned AT for the cheaper and smaller Baby AT form factor, using it for computers that spanned several ...

8. Molex connector - Wikipedia

   en.wikipedia.org/wiki/Molex_connector

   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. This allows the motherboard to remove power upon shutdown (with the exception of the aforementioned 5V standby power ...

9. WTX (form factor) - Wikipedia

   en.wikipedia.org/wiki/WTX_(form_factor)

   Bigger than ATX, maximum WTX motherboard size was 14 × 16.75 in (356 × 425 mm). This was intended to provide more room in order to accommodate higher numbers of integrated components. WTX computer cases were backwards compatible with ATX motherboards (but not vice versa), and sometimes came equipped with ATX power supplies.
