AT-style computer cases had a power button that is directly connected to the system computer power supply. An ATX power supply is typically controlled by an electronic switch. Instead of a hard switch at the main power input, the power button on an ATX system is a sensor input monitored by the computer.

What is the difference between ATX and AT?

Power Connectors AT motherboards use two 12-pin plugs to power the motherboard, while an ATX motherboard uses one 20-pin plug for the power supply. When using an ATX form factor motherboard, you must use an ATX power supply.

What does ATX mean in power supply?

Advanced Technology eXtended ATX (Advanced Technology eXtended) is a motherboard and power supply configuration specification developed by Intel in 1995 to improve on previous de facto standards like the AT design.

What is ATX SMPS?

AT and ATX stand for Advanced Technology power supply and Advanced Technology Extended power supply. Both are types of Switch Mode Power Supply (SMPS). Switch mode power supply provides electrical power to an electrical load. SMPS uses a switching regulator for efficient conversion of electrical power.

What is a BTX motherboard?

B. T. X. (Balanced Technology EXtended) A motherboard design from Intel introduced in 2004 that supersedes the ATX. Unlike the ATX, the placement of all chip sockets in the BTX is defined in order to provide sufficient air flow over the processor and graphics card.

What is the main function of ATX power supply?

ATX power supplies are turned on and off by a signal from the motherboard. They also provide a signal to the motherboard to indicate when the DC voltages are in spec, so that the computer is able to safely power up and boot.

Is BTX better than ATX?

BTX is the newer standard, and is the intended successor to ATX. 2. BTX focuses more on airflow than ATX. BTX requires a certain arrangement of motherboard components to maximize cooling, while ATX does not.

What happened to BTX motherboard?

Titan. Future development of BTX retail products by Intel was canceled in September 2006 following Intels decision to refocus on low-power CPUs after suffering scaling and thermal issues with the Pentium 4.

What is ATX 12V used for?

The ATX 4-pin power supply connector is a standard motherboard power connector used to provide +12 VDC to the processor voltage regulator.

Can I use 4pin power in 8 pin?

It is entirely possible to just plug the 4-pin connector in the 8-pin slot.

What was BTX?

In the petroleum refining and petrochemical industries, the initialism BTX refers to mixtures of benzene, toluene, and the three xylene isomers, all of which are aromatic hydrocarbons. The BTX aromatics are very important petrochemical materials.

Are BTX motherboards still made?

Nope. No consumer btx boards were ever produced afaik. At the time they were strictly an oem affair. So Blaise170 no sorry, its been well over 6 years since a consumer BTX board has been available.

Should power supply fan always run?

No, often the PSU fan will not run unless it is required to cool the PSU.
