Power supply For many PC builders and enthusiasts, the term "AT" in relation to motherboards and their associated power configurations often sparks curiosityChapter 1 Motherboards, Processors, and Memory If you've encountered the phrase "AT style motherboard slot," you're likely wondering what precisely "AT" stands for and its implications for your systemMicro ATX MotherboardsMeasuring 305 mm x 244 mm, ATX (whichstands forAdvanced Technology eXtended) is easily the most commonmotherboardform factor around. This dive into the history and technical details aims to clarify this aspect of motherboard design, exploring its origins, its evolution, and its place in modern computingA Complete Guide to Motherboard Expansion Slots

The term "AT" in "AT style" primarily refers to the Advanced Technology standardThe CPU package is connected to amotherboardvia some form of CPU interface, either aslotor a socket. For many years the socketstyleof CPU was dominant. This standard was introduced by IBM in the early 1980s with their AT personal computer201925—Most mATXmotherboardswill have the primary 16xslotin position '1' nearest the CPU. It would be unusual (but not unheard of) to have the main 16x GPUslot It defined a set of specifications for the motherboard's physical layout, power supply connector, and expansion bus, aiming to bring greater compatibility and expandability to personal computersSATA, PCIe, and M.2 The slots on your motherboard, When discussing "motherboard slot" in this context, it often pertains to the power connectors that were part of this AT standardSATA, PCIe, and M.2 The slots on your motherboard,

In the realm of "motherboards" and their "slots," the original AT standard utilized a distinctive pair of power connectorsAGP is categorized by its ability to increase its signal for each clock cycle, called strobing. The amount of increase is defined as AGP 2x, 4x, and 8x. RAM  These were typically labeled P8 and P9AT stylesystems use two power connectors, P8 and P9 to connect to themotherboard NIC sits in your PC on one of theslotavailable on themotherboard. These multi-pin connectors were responsible for delivering power from the power supply unit (PSU) to the motherboard, enabling the operation of various componentsTypes Of Motherboard The design was functional for its time, but it also had its limitations2022616—MotherboardPCIeslotsare where you'd expect to find the average GPU or network card in a PCIslot. PCIestands forperipheral component  One notable characteristic was the lack of polarization; it was possible to insert the connectors incorrectly, potentially leading to damage to the motherboard or PSUThe processor and memoryslotsare at a right angle to the expansionslots, putting them directly in line with the fan output. This inherent risk of incorrect installation contributed to the eventual evolution of power supply standardsComputer Motherboard Overview and Parts | PDF

Over time, the computing industry advanced, and with it came the need for more robust and user-friendly standardsWhen selecting amotherboard, generally you'd need to pay attention to the form factor, processor socket, chipset, buses and number of busslots, and other  The AT standard, while foundational, began to be superseded2022112—APCIExpress (PCIe) slot is a type of expansion slot on a motherboard that allows you to add additional hardware to your computer. PCI Express  The most significant successor to the AT standard in terms of power delivery is the ATX (Advanced Technology eXtended) form factorA Complete Guide to Motherboard Expansion Slots ATX motherboards, which are common today, utilize a single, keyed 20-pin or 24-pin power connectorMotherboard Components And Their Purpose This keyed design prevents incorrect insertion, greatly improving system reliability and user safety1.2 Differentiate Between Motherboard Components Their The "ATX" standard also expanded upon the original AT specifications, including changes to the motherboard dimensions, mounting hole locations, and the arrangement of connectors on the rear I/O panel2022112—APCIExpress (PCIe) slot is a type of expansion slot on a motherboard that allows you to add additional hardware to your computer.

While the full AT standard with its P8/P9 connectors is largely considered legacy, understanding it is crucial for appreciating the progression of PC hardwareAGP is categorized by its ability to increase its signal for each clock cycle, called strobing. The amount of increase is defined as AGP 2x, 4x, and 8x. RAM  The principles of AT style power delivery and motherboard slots laid the groundwork for subsequent advancementsAGP ExpansionSlots.

You might encounter references to AT style in older hardware or in discussions of historical PC components2024212—PEGstands forPCI Express for Graphics and describes asloton the mainboard that is intended for the graphics card. It is equipped with up  Furthermore, some modern compact form factors, like Flex ATX, are derived from the ATX standard, indicating a continuous lineage from the original AT specificationsCPU interfaces - motherboard slots and sockets for AMD

Beyond power connectors, the term "slot" on a "motherboard" can refer to various expansion interfaces that allow you to connect peripheral devicesCPU interfaces - motherboard slots and sockets for AMD These include:

* PCI (Peripheral Component Interconnect) slots: These were a common expansion slot standard for many years, used for add-in cards like sound cards, network interface cards (NICs), and older graphics acceleratorsMotherboard Components And Their Purpose You might still find older "motherboards" with several PCI slotsTypes Of Motherboard

* AGP (Accelerated Graphics Port) slots: Designed specifically for graphics cards, AGP slots offered a dedicated, high-speed connection for video outputTypes Of Motherboard They were eventually replaced by PCI ExpressA Complete Guide to Motherboard Expansion Slots Older "motherboards" might feature a distinct brown-colored AGP slot located near the PCI slots🔧 Know Your Motherboard!🧠 | Every Port & Slot Explained

* PCI Express (PCIe) slots: This is the dominant expansion slot interface in modern computersThe processor and memoryslotsare at a right angle to the expansionslots, putting them directly in line with the fan output.
