How to connect power supply to motherboard. If you are building your PC and you are not sure where each Power supply cable goes, or if you want to replace your existing supply with a new one, we will show you the PC power supply. How to properly install, and how and where. To connect each of its cables so that you can be sure that everything will work fine the first time.
Installing the power supply is quite an easy process but it has its own art, especially when we have to manage to hide the cables so that they do not get in the way but still stay strong and well connected to avoid problems. Coins Cable routing is important not only for aesthetics, but also to ensure that the airflow in the box is not obstructed.
How to install a power supply
The power supply is very easy to install, and we really need to make sure we orient it properly. Whether the source is modular or not, if the box has a mounting point on the floor, we should keep the fan down, as this is where air will enter (in any case, make sure the ventilation grille in the box (Area), because otherwise, you will have to face the fan (although this is not ideal).
If the mounting point is up, we should check if there is a grill on the top of the box, in which case we should turn the source fan upwards. Otherwise, we will have no choice but to point it down, although this is not ideal as it will get hot air from the rest of the ingredients. However, the growing point of virtually all existing PC cases is down.
We simply put the fountain in place and patch the back of it with four screws.
With that, the source is already installed in the box, but obviously, we haven’t removed it because the part that really matters the most comes down to: wiring management and connection.
Management of power supply wiring
Once we have disconnected the Power supply in the back of the PC case, we should do a cable management that allows us to manage the cables. To do this, we are going to use the right side of the box, from where we will transfer all the power supply cables to the motherboard and the rest of the components.
We can use flanges or strips to group the cables and prevent them from getting too tight, or tangling with each other. Depending on the box you have, you’ll find the process easier or more complicated, so I’m afraid you’ll be forced to learn the importance of buying a box that cares for this section.
Now why do you think so many 3.5% bays leave our hard drives this way?
Where does every wire from the power supply go?
Now let’s look at the cables. The method of channeling them will depend on whether the source is modular and boxed, but each of the connectors and cables must go into place as follows:
SATA / MOLEX peripheral cables
These cables are responsible for powering hard drives, SSDs, rehabs and other peripherals we have. Its use will depend on the hardware configuration we have, because if, for example, we only have one PCIe SSD attached to the board, then these cables will be unnecessary.
In this case, if the source is modular, we do not even need to link them to the source. Both SATA and MOLEX have only one connection position, although they lack tabs, so you can’t go wrong with connecting them.
Cable with 20 + 4 pin ATX connector
This is the first cable that we must channel and connect because it is the thickest and largest, and which will cost us the most to install. Typically, we root the cable behind the motherboard, in the hole that is in all the boxes, and we pull it to the surface of the ATX connector on the motherboard, which is usually in the upper right.
To connect it we just need to see where the tab is, although it will not fit in the opposite direction anyway, it can only be connected in that direction. We just hold the connector up and press it, it will go in automatically (the tab is for disconnecting it, not for connecting it).
Cables with PCI-Express connector
The use of these cables, like SATA cables, will depend on whether or not our graphics card needs extra power. In this case, to hide them, it is better to root them behind the motherboard and take them out a little above the graphics card so that they can be connected without getting too far.
In this case, both 6-pin and 8-pin connectors have a tab and allow them to connect in only one direction. In the case of 6 + 2 pin connectors, two extra pins fit under the six pin connector, no damage. If the connector is 6 + 2 and the graphics card has only 6 connectors then the 2 pin part will remain open. Nothing happens, it happens.
Cable with 4 + 4 pin EPS connector
This cable is easy to root, and as a general rule it should go to the upper left of the motherboard. You will usually need to pull enough cable out of the box to be able to connect it, and then pull it out so that it hides well. Like the 24 pin, it has a tab and can only be attached to one side.
And what about the extra cables?
Whether you edit your source or not, you will have extra cables. In the case of modular sources, it would be sufficient not to connect additional cables to the source, and we should logically secure them in case we need them in the future. In the case of non-modular sources, we have no choice but to connect the cables to the source but we will not use them, and unfortunately we have to keep them there (this is a disadvantage of non-modular sources). .
In that case, the best thing we can do is tie them all together with zippers or metal cables and leave them on the floor of the case so that they do not hang loosely as they affect the air flow in the case. can. This is a bit unfortunate but there is no other option.
How to connect power supply to motherboard: Conclusion
When purchasing a power supply, it is important to ensure that it is the greatest fit for your system before making a purchase. To do this, you must first compare the wattage of your power supply with the power usage of the computer (especially the CPU and graphics card). You’ll also need to pick a power supply that is compatible with the form factor of your motherboard.
