2. Power supply unit (computer) - Wikipedia

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

   Most desktop personal computer power supplies are a square metal box, and have a large bundle of wires emerging from one end. Opposite the wire bundle is the back face of the power supply, with an air vent and an IEC 60320 C14 connector to supply AC power. There may be a power switch and/or a voltage selector switch.

3. 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 ...

   The desktop computer hard-drive connector (AMP Mate-n-Lok 1-480424-0 power connector) is standard on all 5.25-inch floppy drives, 3.5-inch PATA and non-SCA SCSI disk drives; however, newer SATA disk drives employ a more advanced interconnection with 15 contacts. These advanced connection systems were first developed by Molex and other connector ...

5. Motherboard form factor - Wikipedia

   en.wikipedia.org/wiki/Motherboard_form_factor

   For example, a desktop computer may require more sockets for maximum flexibility and many optional connectors and other features on board, whereas a computer to be used in a multimedia system may need to be optimized for heat and size, with additional plug-in cards being less common. The smallest motherboards may sacrifice CPU flexibility in ...

6. LPX (form factor) - Wikipedia

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

   With introducing the PCI bus, the ISA connector was replaced by a riser card connector, mechanical related to the EISA connector. Typical LPX riser card, with connectors for PCI and ISA cards LPX (short for Low Profile eXtension ), originally developed by Western Digital , was a loosely defined motherboard format ( form factor ) widely used ...

7. Motherboard - Wikipedia

   en.wikipedia.org/wiki/Motherboard

   Passive cooling, or a single fan mounted on the power supply, was sufficient for many desktop computer CPU's until the late 1990s; since then, most have required CPU fans mounted on heat sinks, due to rising clock speeds and power consumption. Most motherboards have connectors for additional computer fans and integrated temperature sensors to ...
