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 ...
Power supply may be bad Long continuous beep tone Memory failure Steady, long beeps Power supply bad No beep Power supply bad, system not plugged in, or power not turned on No beep If everything seems to be functioning correctly there may be a problem with the 'beeper' itself. The system will normally beep one short beep. One long, two short beeps
Original IBM power supplies for the PC (model 5150), XT and AT included a line-voltage power switch that extended through the side of the computer case. In a common variant found in tower cases, the line-voltage switch was connected to the power supply with a short cable, allowing it to be mounted apart from the power supply.

Stand-alone switched-mode power supply An adjustable switched-mode power supply for laboratory use. A switched-mode power supply (SMPS), also called switching-mode power supply, switch-mode power supply, switched power supply, or simply switcher, is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently.
Fixing this warped view requires that the motherboard perform an unconditional 64-bit byte swap on all data entering or leaving the processor. Endianness thus becomes a property of the motherboard. An OS that operates in little-endian mode on a big-endian motherboard must both swap bytes and undo the exclusive-OR when accessing little-endian chips.
KVM switch over IP extenders use a dedicated micro-controller and potentially specialized video capture hardware to capture the video, keyboard, and mouse signals, compress and convert them into packets, and send them over an Ethernet link to a remote console application that unpacks and reconstitutes the dynamic graphical image. KVM over IP ...
