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 ...
To reduce the power losses in the 5 V supply, with the introduction of the Pentium 4 microprocessor, Intel changed the processor power supply to operate on +12 V, and added the separate four-pin P4 connector to the new ATX12V 1.0 standard to supply that power.
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.

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 ]
Boards using full-power Intel or AMD CPUs typically use ATX12V 2.x connections and require a case with appropriate power supply and cooling for these more power-hungry chips. Defined by the ATX specification, power supplies with ATX12V connector on a separate 12 volts rail must not idle that 12 volts rail.
By Thomas Escritt. BERLIN (Reuters) -Three parties in the eastern German state of Thuringia joined forces on Thursday to keep the poll-topping Alternative for Germany out of power, electing as ...
A heavily loaded power supply and the computer it is powering generate significant amounts of heat, which may raise the power supply temperature, which is likely to decrease its efficiency. Since power supplies are certified at room temperature, this effect is not taken into account. [5] [15] 80 Plus does not set efficiency targets for very low ...
