The tangled cables within the CPU shell may be intimidating if you are not a frequent PC maker. However, the assembly and connection of the power wires to the motherboard is considerably more accessible than it first appears. All you need to do is locate the proper ports.
Power is necessary for the gear to operate. However, they do not receive electricity directly. Most crucial hardware parts are integrated onto the motherboard and connected by printed circuits. The motherboard is a bridge to power various pieces of internal computer hardware.
Only a few pieces of hardware, including the CD drive, HDD, and a few others, get electricity straight from the power source. Others require you to attach the components to the corresponding port on the motherboard and connect the power connectors to the motherboard. Using this detailed information, let’s learn how to connect power supply to motherboard?
How to Connect Power Supply Cables Properly?
Attaching the power supply cables guide is relatively easy, but there are a few things to keep in mind. I’ll walk you through everything step-by-step about how to connect power supply to motherboard? You can consider it as computer power supply wiring diagram:
6 Steps to Connect Power Supply Cables
1) Add the PSU to the Case
The PSU must get first fast to the casing physically. The pc power supply connections are often located at the bottom back of the case, but this might vary, so check the instructions for your computer case. As there are typically four holes at the back of the chassis that line up with the four mounting points on the PSU, it is effortless to determine where the PSU should be attached.
Put the PSU in the desired location and begin screwing it in after determining the ideal place. Avoid overtightening the screws to avoid damaging the PSU or the case.
2) Attach the Motherboard with the 24-Pin Main Power Cable
The 24-pin power line needs to connect to the motherboard next. The motherboard and all other components are powering by this connector, making it the most crucial one.
The motherboard’s top right corner is often where the 24-pin connector slot can find. Consult the handbook for the motherboard if you can’t find it. Take the 24-pin cable and place it inside the connection at this point. Ensure that the connector’s clip is locked and the cable must insert.
3) Attach the Motherboard’s 8-Pin (4+4) CPU Power Cable
The 8-pin CPU power line needs to connect to the motherboard next. The CPU receives electricity from this connection. A 4+4 pin or an 8-pin connector could use with this cable. If your motherboard includes an 8-pin connector, you can utilize the 4+4 pin cable since it can use as either a 4-pin or an 8-pin connector.
You will only need to utilize a 4-pin cable if your motherboard supports a 4-pin connector. However, a new motherboard will almost certainly include an 8-pin port. Usually found next to the CPU, the 8-pin connector slot must identify by the labels CPU PWR or CPU PWR1. Simply slide the cable into the connector to join it, tuck it in, and secure it fully.
4) Attach your GPU to the PCIe Cable
The next step is to connect a PCIe power cable if your GPU requires one. Typically, the PCIe cable has a 6+2-pin connector. Although most motherboards come with two PCIe cables, if yours doesn’t, you can purchase one. Look for a 6+2-pin cable marked PCI E or PCI E1 to identify the PCI cable.
5) Attach Your HDD to the SATA Cable
The data and power cables are the two different types of SATA cables, as you already know if you’ve read our guide on SATA cables. The data cable links the HDD to the motherboard, whereas the PSU cable is the one I’ll be talking about for delivering power to the HDD/SSD.
The 15-pin SATA power connector mark with the letters SATA PWR or PWR SATA. It is a component of your power supply cables and has a recognizable shape. The next step is to attach the SATA power cord to your HDD when it exists. To accomplish this, merely lock the cable and fully enter it into the SATA connections on your hard drive.
6) Connect Your PSU and the AIO Cooler
Since not everyone has an AIO cooler, not everyone will need to do this. The next step is to connect it to the PSU if you have one. AIO coolers typically feature SATA power connectors, so join the SATA power cable to your AIO cooler in the same way as you did in the previous step to connect it to the HDD.
You must complete all these procedures to connect the cables to your motherboard. As I previously stated, completing it shouldn’t take more than 10 minutes. After reviewing the fundamentals, let’s discuss building modular power supply cables and managing cables.
After learning how to connect power supply to motherboard? Let’s move to taking a look at different types of PSU Cables.
Types of Power Supply Connectors and their Function
There are many different power supply connectors types. Fortunately, they must make it so that installing them cannot go wrong. When you attempt to attach the incorrect header, the cable will not fit in the connection slot. Learning about the various power supply cable types and their uses can be intriguing. Therefore, let’s begin.
ATX Connection P1 (PC Main)
The Power Supply Unit (PSU) responsibility is to supply power to your motherboard. The 20-pin or 24-pin connector must use for this. A 24-pin cable can divide into 20- and 4-pin segments and is backward compatible with motherboards with 20 pins.
P4 (EPS Connector)
The motherboard’s pins eventually became insufficient for powering the processor’s (CPU) core. Since overclocked CPUs can consume up to 200W of power, it became necessary to supply power directly to the CPU. The P4, or EPS connector, is now used to power computers.
A 4-pin connector must include in budget motherboards. 8-pin connectors it found on more expensive “overclocking” motherboards. The additional four pins make sure that the CPU may receive enough power when being overclocked. There is absolutely no need for extra pins for regular use.
Connector for PCI-E (6-pin and 6+2 pin)
The motherboard’s PCI-E interface slot can deliver a maximum of 75W. More power must need for dedicated graphics cards that are faster. They created the PCI-E connector to address that problem.
75W more power per cable can supply using the PCI-E 6-pin connector. A single 6-pin socket on your graphics card allows it to draw up to 150W. The 6+2 pin PCI-E connector is necessary for more expensive graphics cards. This connector’s 8 pins can deliver up to 150W per cable. A graphics card can take up to 225W from a single 6+2-pin socket (75W from the motherboard plus 150W from the cable).
Molex (4 Pin Peripheral Connector)
The long-used Molex connectors can supply 5V (red) or 12V (yellow) to peripheral hardware devices. Once frequently used these individuals to connect hard drives, CD-ROM players, etc.
Even some graphics cards, such as the Geforce 7800 GS, used Molex connectors. Because of their low power consumption, PCI-E and SATA connections have mostly taken over their functions in modern times. Powering the case fans is all that is left.
The Molex rendered useless by the SATA connector. SATA power supplies power to all current DVD players, hard drives, and SSDs.
A 24-pin connector system underwent alteration with the release of ATX12 V2.0. An older 20-pin connector you use by the ATX12V (1.0, 1.2, 1.2, and 1.3) models. The ATX standard has over 12 different iterations, but they are all so similar that compatibility issues are not a concern.
How to Connect Power Button to Motherboard Gigabyte?
Connect wires to the Gigabyte motherboard’s internal connectors and headers, such as the front panel audio, USB, IEEE 1394, and IDE/SATA connectors. Depending on the case design, attach the front panel module, which includes the power indicator, hard drive activity indicator, speakers, reset switch, power button, etc.
How to Connect Power Button to ASUS Motherboard?
All of the components inside an ASUS computer’s power supply unit are in charge of supplying the device with power. Some of these parts build into the motherboard, including the component regulating how the power switch behaves.
Pushing the power button will have no effect if the power switch cable separates from the motherboard. You can service the PC on your own to prevent downtime for your company rather than sending the workstation in for repairs, which could take weeks.
- Put the computer to sleep. Unplug the power cable after waiting for the indicator lights on the PC’s front to go out.
- Press the power button to shut off the motherboard’s power. Remove all other cords and hardware from the PC.
- Orient the case so that the ASUS’s back is facing you. Place the computer on the side that is farthest from the vents.
- The screws holding the side panel to the computer should be loosened and removed. To remove the panel from the computer, move it back toward the case.
- Set aside the panel. To ground yourself, touch an unpainted metal surface like the chassis.
- On a few ASUS models, the power switch connector must link with the LED connectors. Find this connector. Several wires of different colors will frequently make up the cable.
- The power switch slot is next to the SATA ports. Insert the connector into this slot.
- To put the ASUS PC back together, perform the previous instructions backward.
How to Connect Power Button to ASRock Motherboard?
You should be able to connect your power button to your motherboard by following the instructions below. So let’s get started.
- On the motherboard, there are the pins for the power switch. Finding the front panel header is not tricky. You can refer to your motherboard’s handbook. To determine the pins, you can also physically examine your motherboard. The majority of the headers have labels indicating what tasks they do.
- A motherboard has a lot of pins, and each one of them has a specific function. Power on the switch, reset switch, power LED, and other parts are only a few of their uses.
- The front panel header finds that the power on switch pins should be next sight.
- The power switch jumper must connect to the power switch pins. The PC casing includes the power jumper wires as well. It emerges from the case’s front panel along with other jumpers that have different functions.
- You could occasionally see some polarity signals on the label of the power switch pins. When considering switching, it makes no difference if this indication is positive or negative. For the jumper, either terminal will function. All you need to do is make sure the circuit is closed.
The P4, or EPS connector, is now used to power computers. A 4-pin connector must include in budget motherboards. 8-pin connectors must find on more expensive overclocking motherboards. The additional 4 pins make sure that the CPU may receive enough power when being overclocked.
Manufacturers’ PSU cables may be wired differently from one another. Consequently, using PSU cables made by companies other than the one that made your power supply unit can be unsafe. The cord itself will, at best, not be able to power your PSU
It is useless if a power supply can’t connect to and power every part of your computer. That implies that it must have each necessary sort of connector. The main connector that powers the motherboard should be taken into account first. There are two varieties of this connector: 20-pin and 24-pin.
