Assembling a PC isn’t too mysterious, but when it comes to connecting all the cables, many users can get overwhelmed and make mistakes. If this is your case, don’t worry because below we are going to explain to you what would happen if you incorrectly connect the cables from the case to the PC motherboard, and of course how to connect them correctly.
What happens if I connect the PC case cables incorrectly?
Although it may seem that by incorrectly connecting the cables the computer could explode, in reality, by incorrectly connecting them or crossing them, the only thing that could result is that the buttons or associated components would not work .
However, it is advisable to connect them all well, mainly because when we buy a computer what we want is to use it, unless you feel like experimenting, but as we have indicated previously nothing would happen.
How do the cables connect well?
In short, each cable connects to the place where it indicates its name, although there are times when it can become complicated depending on the type of card we have, that is why we are going to show you how to do it.
Most of the cables that are connected and have the basic functions of the box (power on, off, restart) all go to the same place, pins usually located in the lower right area of the board, indicated with the name “panel” . , “f_panel” or directly “front panel”:
However, we can make the mistake of relating them backwards, and this is more common than it seems. The trick to being able to put everything back in its place is quite simple, the part where the name of the cable is written must always point outwards. If even with these we are unable to connect the cable correctly, there are plastic pieces that indicate exactly where each cable should go and then connect them all. Some motherboards include them to make computer assembly easier.
If you know how to locate the pins where it says “panel”, then you will have already figured out where to connect the internal speaker, as these are in the same area where the basic function cables are connected.
For the USB ports, there are different connectors that must be found depending on what our box has, these being the following:
USB 2.0, the design of the cable makes it easy to find the connector, since they are the ones that have 2 rows of 5 pins, one is missing and no, it’s not that it’s broken.
USB 3.0 we can still count the pins, but with this feature cable it’s almost not necessary, as its large shape tells us where it connects. It has 20 pins and connects where it says “USB3”
USB Gen 3.x Type E, a name that at first glance may sound like a science fiction film, but don’t worry, it is only the connector for the latest generation USBs. In this case you have to be careful when connecting, because if you force too much on the cable it is likely that you will break one of the pins, this should not be the case, because the shape allows it to be quite intuitive, even if you don’t connect it to the first one, you can do like with the USBs and put it upside down then turn it over, it never fails when you connect one.
The fan cables are very easy to connect, since the plastic on which the name is written contains a notch that tells us at all times if we are putting them correctly or incorrectly, just follow this diagram and connect them where it indicates “SYS_FAN”. It should not be confused with the “CPU_FAN” indicator since these are used to connect the processor cooling.
And at the end, all we have left are the audio cables, these two cables, HD AUDIO and AC’97, connect where their name indicates, it appears screen printed as “AAFP” or “HD AUDIO”. The difference between one and the other only depends on whether it is older, currently most of them usually appear as HD AUDIO. They are easy to connect because they have a notch on one of the pins which prevents a bad connection.
