Suggested March 2024 How To Connect Power Supply To Motherboard

If you are not a regular PC builder, it might be daunting to see the profusion of tangled wires inside the CPU casing. However, it is much simpler than it appears to assemble and connect the power cables to the motherboard. You just have to find the correct ports and that’s all.

It is obvious that the hardware requires power in order to function. But the power is not directly supplied to them. Most of the essential hardware components are embedded into the motherboard with printed circuits between them. The motherboard acts as the bridge to supply power to several internal hardware in a computer. 

Only the CD drive, HDD, and some other hardware receive power directly from the power supply unit. For others, you need to link the power connectors to the motherboard and attach the components to the respective port on the board. 

With this comprehensive guide, we are going to learn how to connect the power supply to the motherboard.

When you bring the power supply unit or PSU out of the box, you will see a number of wires with connectors at the end. Each of the connectors is meant to supply power for different hardware. It is quite confusing to find the right one for each of them. 

So, let’s start to connect the power supply to the motherboard step-by-step by arranging a screwdriver set and the will to do the work.

The first thing to do is to place the PSU in the CPU casing. Most of the casings have a box-shaped empty space at the top to keep the PSU. If you have modified your system and have bought a custom casing, then you will have to look at its manual to find the space.

You can follow the instructions given below to assemble the PSU to the casing.

Now that you have assembled the PSU successfully, let’s move on to connect the cables.

This cable is one of the biggest connectors and provides the juice to run your entire motherboard and its components.

The reason we are writing the pin as 20 (+4) is that the connector has a bigger portion with 20 pins and a separate one with 4 pins. The reason behind this is to facilitate the older motherboards that had only 20 holes to insert the pins.

Since it is the biggest port on the motherboard, except for the RAM and graphics card slot, you should not miss it.

Let’s see how you can install the connector to your motherboard.

Now, let’s look at the way to connect other power pins to the motherboard.

Another cable that your will find coming out of the power supply is a 4 (+4) pin CPU power connector. This cable supplies power to run your processor.

But it does not matter how big the connector is. The process to connect it is the same. Here is how you do it.

Your processor can work with just a 4-pin connector even if it has a port requiring 8-pins. However, it might malfunction due to insufficient power and I would not recommend doing that.

But for the higher-end board with two 8 pins requirement, you can just insert one and it will do the job. You need to insert the remaining if you want to do extra pieces of stuff such as CPU overclocking.

Now that you have powered your motherboard and CPU, let’s go to know about the other connectors.

Earlier, we did not have heavier programs and we worked out with no or lower capacity video cards. These graphics cards could power themselves up by taking the elixir directly from the motherboard.

However, as our desire increased, the capacity and hence the power required for the video card has risen. The graphics card that we use today may require power directly from the PSU. For that reason, the PSU manufacturers provide us with a cord with 6 pins and removable 2 pins to power up the video card.

Similar to the processor, the power required for the graphics card also varies according to the type. Some require 6 pin while some require 8 pins to run it. Here is the way to connect either of them to the right port.

Furthermore, there can be two different connectors, one for the video card and another for the CPU, having 8 pins on both. To differentiate which one belongs where you just have to look at the structure. The connector for the CPU has split in the middle and others mostly have split making 6 and 2 separate pins.

Let’s see what job the remaining cables have on your computer.

Among the Hardware in your computer that requires direct power from PSU, Hard Disk Drive, SSD, CD/DVD-Drive, etc. are some of them. These hardwares uses the mentioned SATA connector to receive the power.

If you learned how to connect other connectors, then it is also equally simple. Here is the way to do it.

These cables are optional to use except for the HDD or SSD. You generally get atleast 2 SATA connectors. You can leave the remaining ones untouched if you do not have additional hardware needing these.

If you have become perfect at connecting the SATA cable to different hardware, let’s learn about its older brother, the Molex connector.

Remember the older Hard drives that had a number of pins behind it? You must also have immediately thought about the cable to power up the HDD through PSU. That cable is the Molex connector.

Nowadays, the Molex connector does not have much use. However, the manufacturers of PSU like to stay on the safe side providing these cables to the unit. If some users still use the older HDD and motherboard, it is best to have at least one Molex connector in the PSU.

This works similarly to the SATA cables. The SATA cables can be said as the replacement of the Molex connector.

Let’s see how to recognize the Molex connector and the way to connect it.

Find a connector with 4 holes on it with no extra parts.

It is the simplest of all that powers the HDD or CD/DVD drives or sometimes a casing fan.

You will see a slightly curved surface and a complete rectangular surface on the connector.

Find a port on the back of the respective hardware.

Keep the orientation of the connector such that it goes inside the port easily.

It also can be linked only in a single way as other connectors.

There can be an additional small 4-pin connector coming out of the PSU. This pin is similar to a Molex connector but only smaller. This pin is there to supply power to a Floppy Disk Drive.

The process to connect the pin for an FDD is similar to other connectors. Most of the systems, at present, have no FDD in them and this connector is mostly rendered useless now.

You have now learned the way to connect all the power cables to different parts on a motherboard with hardware. If you manage the cables cleanly with zip ties or some process, you can easily assemble all the connections in your computer.

How To Get To Bios On An Msi Motherboard

Your computer’s BIOS displays your current hardware configuration and other related information. You can also change such settings on the BIOS. 

You can only access BIOS on legacy hardware. But all modern MSI motherboards have UEFI (Unified Extensible Firmware Interface) instead of BIOS.

There are two ways to access BIOS/UEFI on an MSI motherboard. Before Windows 8, you could only go to BIOS using the key. But now, you can either use the BIOS key or access BIOS from the Advanced Startup. 

The most convenient method of accessing BIOS on your MSI PC is to press the BIOS key on startup.

If you are using a USB keyboard, the connected USB port may not allow loading BIOS by pressing the BIOS key. Only certain ports allow this shortcut on a PC. So, reconnect the keyboard to other ports and try again in such scenario.

The necessary steps to access BIOS using the BIOS key are as follows:

In some PCs, the BIOS key is F2 instead of Del, but it’s rare.

You can also access the UEFI/BIOS on the MSI motherboard from the Advanced Startup or Windows Recovery Environment. It is the diagnostic environment you can change your startup settings. You can also repair system errors without logging in to a user account from this environment. 

First, you need to access the Windows Recovery Environment (WinRE). There are many ways of doing so, such as:

With Force Shutdowns

Force shutdown your PC thrice in a row. You can perform a force shutdown by pressing the Power key for a few seconds until you hear a sound. The fan should turn off, and all LED lights should go off. Also, don’t forget to power up the computer before doing the subsequent shutdowns.

From Windows Settings

To go to Advanced Startup or WinRE from your Settings,

Using Shift + Restart Shortcut

The CLI command shutdown /r /o /f /t 00 or shutdown /r /o also allows you to restart your PC to WinRE. The flags indicate the following:

You can use this command on the Command Prompt, PowerShell, Run (Win + R). Or you can create a shortcut and use the command as the location.

Using a bootable drive is the best option to access WinRE if you have severe system or boot errors. If your system is fully functional, the previous methods are more convenient. Here are the necessary steps:

After accessing the Windows Recovery Environment, it’s time to go to the UEFI settings. Follow the instructions below to do so:

There are many changes you can make from the BIOS/UEFI settings. The BIOS settings specify how your system controls and manages the hardware components. Some important configurations you can alter are as follows:

Boot device order.

Processor, fan, or RAM speed.

System date, time, and language.

Enable or disable Virtualization.

Secure boot and TPM settings.

If you haphazardly change the BIOS settings, your system may suffer from certain issues. At such times, it’s better to reset your BIOS to the default settings. On the MSI BIOS, press F9 and select Yes to do so.

After changing BIOS setting, press F10 and select Yes to save the changes and restart your PC.

If you can’t go to BIOS settings using one of the methods we have provided, try the other. You should always be able to reach BIOS from the Advanced Startup as long as your OS is fully functional. But if you want to use the key shortcut but can’t, there are a few things you can try.

First, try changing the USB port if you are using a USB keyboard as we mentioned earlier.

You should also disable fast boot on your PC. Fast boot significantly decreases the startup time, so you might miss the time limit to press the BIOS key. You need to turn it off for both OS and MSI BIOS settings. For the former, we have a dedicated article on How to Disable Fast Startup on Windows. Check it out to learn the necessary steps.

And the easiest way to disable the MSI fast boot is to reset your BIOS. You can do so by removing and reinserting the CMOS battery.

How To Allow Guests To Connect To Your Wi

When guests come to your house, you can share your Wi-Fi password without actually telling them the network name and password. This is made possible by converting your Wi-Fi credentials into a QR code that your friends and family can quickly scan to connect to your Wi-Fi. No speaking the password and no typing the password!

The entire process is uncomplicated, and in this tutorial, we guide you through all the necessary steps.

How to generate a Wi-Fi QR code for your guests

Using a browser-based website, you can generate a QR code that will automatically connect your friends and family to your Wi-Fi network when scanned. Simply print this QR code and leave it in a drawer or maybe in the guest bedroom of your house.

This is particularly helpful if, like me, you have many guests visiting your home, and you don’t want to leave your Wi-Fi password on a post-it note for everybody to see. Plus, if it’s a big gathering, say a holiday dinner, manually telling or typing the password for dozens of people trying to get online can get tiresome. Thankfully, sharing your Wi-Fi password is a charm in this age of QR codes.

Follow these steps to share your Wi-Fi password and let people join your Wi-Fi network using a QR code:

Visit in a web browser.

Enter your Wi-Fi network’s name in the SSID (Service Set IDentifier) field.

For Encryption, make sure WPA/WPA2/WPA3 is selected as most routers use this.

In the Key field, type your Wi-Fi password.

You can export this QR code as a PNG image, screenshot it, or print it.

How will my guests connect to my Wi-Fi using the QR code

Guests using iPhone or iPad

From now on, visitors coming to your home with an iPhone or iPad running iOS 11 (released in 2023) or later will simply have to open the built-in Camera app, be in PHOTO mode, and point the camera at the QR code. Next, tap Join “Your Wi-Fi Name” Network and confirm by tapping Join.

For more:

Guests using Android

As for your guests using an Android phone, they will have to download a bar code scanner app from the Play Store. QiFi recommends Barcode Scanner by ZXing, but feel free to use any. However, if your guest’s Android phone runs Android 10 (released in 2023) or later, just like iPhone, they can simply open the built-in Camera app to scan the QR code and join your Wi-Fi network.

Guests using MacBook or Windows PC

The webcam on a MacBook or Windows laptop doesn’t read QR codes. There are apps like QR Journal for Mac and QR Code for Windows 10, and I tried the former on my MacBook, but it didn’t successfully scan the Wi-Fi QR code using the built-in camera. However, there is another way to address this.


Is it safe to share your Wi-Fi password with this web app?

Yes. According to the developer, this web app will “render the code in your browser, on your machine, so the Wi-Fi stays as secure as it was before.” The developer also invites people to read the web app’s code, which is available on Github, for extra peace of mind.

Is it safe to share this QR code with my guests?

Let’s put it this way; it’s probably safer to share a QR code with one of your guests than to share the actual password to your Wi-Fi network in plain text.

What if I change my Wi-Fi name or password?

You will have to follow the above steps again and generate a new QR code if you change your network’s SSID (name) or password.

Other ways to effortlessly share your Wi-Fi password with friends and family

Use built-in iOS Wi-Fi sharing

iOS, iPadOS, and macOS have a built-in feature that shares your Wi-Fi password when someone known to you, like a friend or family, is nearby and they try connecting to your Wi-Fi. All you have to do is tap Share Password. You can learn more about this in our dedicated tutorial: How to easily share access to your Wi-Fi network without revealing the password

Use your Android phone’s built-in Wi-Fi sharing

Given the diversity of the Android world, it won’t be true to say all current Android phones, but several Android phones make it a child’s play to share Wi-Fi passwords. My wife uses a four-year-old Android phone, and to share the Wi-Fi password, all you have to do is:

Tap the connected Wi-Fi name where it says Tap to share password. Instantly it will show a QR code that others can scan to join this network. I can even screenshot or print this QR code for later use!

I hope by now you know how to turn your Wi-Fi credentials into a QR code and have guests scan it. So, when you have several visitors this holiday season, make sure you print your Wi-Fi QR code and hang it in the living room.

Uninterruptible Power Supply (Ups) � � Definition Block Diagram Types And Applications

In this article, we will discuss the uninterruptible power supply (UPS), its block diagram, types, and applications. So, lets’ begin with the basic definition of the uninterrupted power supply (UPS).

What is a UPS?

UPS stands for Uninterruptible Power Supply. An Uninterruptible Power Supply (UPS) is the case of a main power supply failure. A UPS or uninterruptible power supply uses batteries and supercapacitors to store electrical energy and delivers this stored electrical energy when the main input power supply fails. However, a typical UPS battery can supply electrical power for a short duration. Hence, UPSs are mostly used as short run time backup power sensitive equipment such as computers, data centers, TV sets, industrial process control and monitoring systems, and many other electronic devices.

A UPS is commonly used with computers that keep running a computer for a short time, about 15 to 30 minutes, after the failure of supply mains. Therefore, it prevents the sudden turn off of the computer and loss of data in the system, and other system failures. These days, there are several types of UPS systems available in the market. Some smart UPS systems are also available that come with software components that enables us to automate the switching function of the backup supply when we are away from the computer system.

Major Parts of an UPS

Following are the main components of a UPS system −

Battery − The battery works as the energy storage unit in the UPS system. It provides the stored electrical energy for a sufficient amount of time during main power failure.

Rectifier or Charger Circuit − It converts the supply voltage of 240 VAC into 12 V (or any other battery voltage) DC. It supplies this rectified DC power to the battery for storage.

Inverter − It converts the DC output power of the battery into ac power to supply the load during mains power failure.

Static Switch − It is a semiconductor device such as a thyristor which transfers the load from the utility to the inverter (and the inverter to the utility) without any interruption in the power supply to the load.

Primary Function of a UPS

When there is any failure in the main power supply from the utility, the UPS supplies emergency power to the load for a short duration of time. This is the primary function of a UPS. Modern UPSs can also provide protection against electrical faults such as short-circuit, voltage fluctuations, low voltage, instability of mains frequency, etc.

Types of UPS

The uninterrupted power supply (UPS) systems are broadly classified into the following three types −

Off-Line UPS

On-Line UPS

Line Interactive UPS

Now, let us discuss each of these three types of UPS systems individually along with their block diagrams.

Off-Line UPS

The Off-Line UPS is also known as Standby UPS. This type of UPS system gives only the most basic features. In the case of off-line UPS, the system will start operating only when there is a power failure in the supply mains. The block diagram of the off-line UPS is shown in Figure-1.

In an off-line UPS system, the ac power from the supply mains is first converted into DC power using a rectifier circuit and then stored in the battery connected to the output port of the rectifier. When, there is any power failure that occurs in the supply mains, the dc power of the battery is converted into ac power using a power inverter and is then transferred to the load connected to the ups system. The off-line ups systems provide surge protection in addition to the emergency power. These are the least expensive UPS systems available in the market.

On-Line UPS

The On-Line UPS system uses a double conversion method. That means, in this UPS system, the input AC power is first converted into DC power by a rectifier to charge the UPS battery, and then this DC power is converted back into AC power by a power inverter to power the load equipment. Therefore, the On-Line UPS systems are commonly used in such systems where electrical isolation is required between the input and output. The block diagram of a typical On-Line UPS system is shown in Figure-2.

In this system, the rectifier circuit receives ac power from the supply mains and directly drives the inverter circuit. Thus, it involves two simultaneous conversion processes and is hence referred to as a Double Conversion UPS System.

In the case of supply mains power failure, the rectifier circuit becomes inactive and the DC power stored in the battery is converted into AC by the inverter and supplied to the load. Once the mains power is restored, the rectifier circuit again starts charging the battery. A current limiting mechanism is also provided in the system to protect the battery from overheating. Although, on-line ups systems are slightly expensive due to their design and components used.

Line Interactive UPS

The Line-Interactive UPS systems are connected in parallel with the AC mains in a standby configuration so that these systems can interact with the AC input system. These types of UPS systems are mainly used in small businesses and offices. The block diagram of a line interactive UPS system is shown in Figure-3.

Under normal operating conditions, the load is supplied with AC power through a parallel connection of the AC source and the bidirectional converter. The converter charges the battery, and also provides AC power to the load in the situation of breakage of supply mains. In this type of UPS system, a bypass is also provided which transfers the load to a bypass AC input when the UPS fails to function. The line-interactive UPS systems are well suited for

Applications of UPS

These days, UPS systems are very common in almost all electrical and electronic systems. Following are some of the important applications of different types of UPS systems −

UPS systems are used in computer data centers.

UPS systems are used in industrial control and monitoring systems.

UPS systems are also used in telecommunication systems.

They are also used in hospitals, banks, insurance offices, and other commercial applications for backup power, etc.


From the above discussion, it may be concluded that the UPS is an electrical device used to provide emergency electrical power under the failure of supply mains. Modern UPS systems are also able to provide several types of protection such as short circuit, low voltage, voltage fluctuation, frequency variation, etc.

Based on the design and operation, the UPS systems are classified into three main types namely off-line UPS, on-line UPS, and line-interactive UPS. UPS systems are widely used in computer systems, houses, businesses, and industries as backup power supply systems.

If you own a Windows computer, you know the importance of having updated device drivers, but have you ever thought of updating the motherboard’s resources?

The motherboard, unlike most other devices, is sometimes not easily identifiable in the Device Manager, and sometimes it is hidden, and to view it you have to unhide them.

Keep reading this article to learn how to update your motherboard resources in the Device Manager and also unhide it if it is hidden.

Windows generally have a large catalog of drivers, and they do update the drivers with every Windows update, but the problem is that they are not the latest version, and they lack drivers for most of the devices.

Windows 11 also installs default drivers that help your PC work without any issues.

But, if you are facing any issue or a component has completely stopped working, you might have to update the device with updated drivers.

Where do I find the motherboard resources in the Device Manager? 1. Unhide system resources 2. Manually updating the drivers

Repeat this process for every driver under System devices to keep your motherboard’s resources updated with the latest drivers.

3. Automatically updating the drivers

When you update motherboard resources, you are not updating the drivers for the motherboard itself. Instead, you are updating drivers for all the components that are attached to the motherboard, such as the CPU, RAM, peripheral devices, etc.

The motherboard itself doesn’t require drivers, but you do require drivers for the hardware components and peripherals that are connected to the motherboard.

Drivers act as a bridge between software and hardware, and they help the hardware components of your PC communicate with the software. 

Without the drivers, your PC cannot communicate properly and your PC will show performance issues. And if you are running outdated drivers or drivers that have been corrupted, your PC can malfunction and stop working.

By updating the drivers regularly, you can have your PC run efficiently and at maximum performance. You will also avoid running into problems such as network issues, audio issues, and whatnot, which are the result of having outdated or corrupted drivers on your PC.

The motherboard hosts all the components, and to connect the hardware with the software, manufacturers release drivers that help these two communicate with each other.

It is always recommended to update every device driver with the latest one so that your computer runs error-free.

We hope this article has helped you learn how to update your device’s drivers properly.
