Motherboard Pin Connections

[Wampanoag]

What are the primary step to replacing a motherboard in a desktop PC is to eliminate the old motherboard. That might resonance trivial, but it is correctly half of the job, and I am splitting elimination and installation onto two pages so it does not get too big. In order to eliminate the motherboard, you not merely have to disconnect the entire connections between the motherboard and components in the case, you be supposed to in addition eliminate any cables that are basically in the way. But I am getting confused with the pin connector of motherboard always. I need some details on them.

One of the mostly significant connections in the PC is that connecting the power supply and the motherboard. It is from side to side this connection (or set of connections) that the a variety of voltages and additional signals are sent connecting these two important devices. (You might desire to familiarize yourself with these signals in the section on power supply functions if essential.) The different form factors utilize dissimilar numbers, types, shapes and sizes of connectors between the power supply and motherboard.

The majority significant characteristic of a wire is its size, and additional particularly, its cross-sectional area. The motivation is that the resistance of the wire is inversely comparative to the cross-sectional area of the wire. Thicker wires be able to carry additional current, at the same time as the higher resistance of small wires causes heating when they are subjected to a high current, which be able to be hazardous. In view of the fact that some wires necessitate to carry additional power than others, they are given dissimilar thicknesses. In addition, most motherboard connectors have multiple wires for the major voltage levels. This permit for supplementary current, spread out connecting the different wires.

In the electronics world solitary standard used for wire thicknesses is American Wire Gauge, or AWG for short. The minor the AWG number, the superior the wire. These numbers go from 0 (below 0 essentially) to 50 and on top of, but for electronics the majority common gauges are connecting 8 and 24. For motherboard connectors the wires are frequently AWG 16, 18, 20 or 22. You determine to notice that the numbers are not linear with the definite size of the wire; AWG 16 wire is approximately four times the cross-sectional area of AWG 22 wire.

The supplementary issue of interest to us concerning wires is the color of their insulation. There are standards recognized for the colors of a variety of wires, to help keep away from confusion by those who run with dissimilar components and PCs. At the similar time as not the entire manufacturers follow these conventions, most do. If they do not, troubles be able to easily happen when a technician sees a black wire, assumes it is a position (which it frequently would be) and then finds out the hard way that it is not.

The color of every pin is the color of the wire recognized as a customary for that pin. Outside the rectangular outline of every connector, next to every pin, is a representation of the recommended AWG size for the wire going to that pin, and the name of its signal or voltage. You have to make a note of that the diagrams are not to scale. You have to make a note of also that they are shown from the perception of the connector coming from the power supply. For individuals connectors with two columns of pins, the mating motherboard connector determine to have its pins in a mirror-image arrangement.

The major trouble with the design IBM used for these power connectors is basically the reality that there are two of them and they are the similar size and shape. The connectors are actually keyed so they cannot be inserted backwards, but it is extremely probable to accidentally swap them. If you do this, you determine to be putting ground wires where the motherboard expects live power and vice-versa, and the results would be disastrous. Thus, technicians running with older systems developed the well-known mantra: "black wires together in the middle".
