What is 20 24 pin ATX connector?

The 24 pin motherboard connector is actually just the 20 pin connector with 4 extra pins added on the end. The original 20 pins were unchanged. The extra 4 pins are not separate rails. They’re just extra lines to provide more current to the same rails.

What does the ATX 24 connector do?

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.

What is a 24 pin ATX connector?

The ATX 24-pin power supply connector is the standard motherboard power connector in computers today. The connector itself is a Molex 39-01-2240 connector, often called a Molex Mini-fit Jr.

What is the use and function of 20 24 pin Molex connector?

In 20/24-pin configurations, the Mini-Fit Jr. connector may be used on ATX motherboards as the main power connector. The same style of connector, in single or paired 4-, 6-, or 8-pin configurations, may be used for additional CPU power and graphics card power.

What is the purpose of ATX?

Short for Advanced Technology eXtended, ATX is a specification used to outline motherboard configuration and dimensions to improve standardization.

Can you use a 20 pin on a 24 pin motherboard?

Technically, a 20-pin ATX connector can be plugged straight into a 24-pin motherboard socket, leaving male pins 11, 12, 23, and 24 unconnected. If you exceed current rating of a connector, it may overheat and even melt.

Do all PSU have 24 pin?

There are many types of PSUs. If it’s a computer PSU then yes it will have a 24pin ATX connector like it always did since >20 years ago. Yes. If it’s actually ATX, then it’s been since the ATX format became popular, which could easily be 20 years ago.

What is ATX cable in computer?

An ATX style connector is a replacement for the older P8 and P9 AT style connector. It is one of the largest connectors inside a computer. It connects a power supply to an ATX style motherboard. With the introduction of ATX-2, this cable is now a 24-pin cable and no longer a 20-pin cable.

What is a 20-pin connector?

It is one of the largest connectors inside a computer. It connects a power supply to an ATX style motherboard. As shown in the picture, the 20-pin cable is a multi-color cable and may be labeled as P1.

What is the function of 24 pin power connector?

A 24-pin power supply adds an extra line each of 3.3 volts, 5 volts, and 12 volts, as well as an additional ground. These extra lines are used to satisfy the needs of newer technologies and more power-hungry peripherals. They also replace older 12 volt auxiliary connectors found on some 20-pin motherboards.

What is the difference between 20-pin and 20/24 pin ATX power supplies?

The 20-pin version may still be used on some more space-constrained motherboards, so some power supplies include a connector where the extended 4 pins can be split off from the 20-pin base connector. The 20/24 pin ATX provides primary power to the system. It powers all directly connected components and SMDs, and provides power to PCI-E devices.

What does a 20+4 pin power connector do?

Main power connector for the motherboard. On a 20+4 Pin connector, four of the pins are on a separate block making it reverse compatible with the older motherboards that require only a 20 pin connector. Connects to the motherboard ATX 12V socket. Provides additional power to the CPU. Connects to the motherboard EPS 12V socket.

What is an ATX power connector?

An ATX power connector is a 20- or 24-pin primary connector that specifically plugs and supplies power into an ATX-type computer motherboard. This in turn distributes power to internal components, such as the CPU, memory module, hard disk and graphics card.

What is a 4 pin ATX 4 pin connector?

4+4 Pin ATX/EPS. A hybrid of the 4 PIN ATX12V and EPS 12V connectors that can be split in half or combined to accommodate either the EPS 12V Socket or the ATX 12V socket. Provides additional power to the CPU.
