24 Pin Motherboard Power Connector Pinout

24 Pin Motherboard Power Connector Pinout The original atx standard supported a 20 pin connector with a very similar pinout as the 24 pin connector but with pins 11, 12, 23, and 24 omitted. this means the newer 24 pin power supply is useful for motherboards that require more power, and therefore eliminates the need for atx 12v power supplies to provide an auxiliary power cable. There are numerous peripheral power connectors on an atx power supply. a modern desktop computer system has two motherboard connectors: a main 24 pin power supply connector which is an extended version of the original 20 pin version; a 4 pin auxiliary connector, that supplies additional power to the cpu.

24 Pinout Voltage At Atx Power Supply To The Motherboard 18 awg is recommended for all wires except pin 11, which should be 22 awg. for 300w configurations 16 awg is recommended. pinout of atx (atx12v) 24 pin power supply connector and layout of 24 pin molex 44206 0007 connector and 24 pin molex 39 01 2240 or equivalent connectoratx 2.2 and later (atx12v 2) is common atx standard, 24 pin connector. The atx 24 pin main power connector is the standard motherboard power connector used in nearly every computer. the connector itself is a molex 39 01 2240 connector (aka, molex mini fit jr). this is the large 24 pin connector that usually attaches near the edge of the motherboard. Below is the (20 4) pin atx connector that came with my evga supernova 550 g3 psu. i can effortlessly connect this type of connector to the motherboard header that has either a 24 pin or a 20 pin setup. here’s a quick overview of the atx power connector pinout. each of these pins on the connector have a specific purpose on your system. The rated current of the main molex connector is 6a per contact. this means with the old 20 pin style you can't get more than 18a from 3.3v and 24a from 5v. that's why in early 2000's, some motherboards with 3.3v >18a and 5v >24a (mainly dual cpu amd systems) used an auxiliary 6 pin power cable.
