WEEK 5 POSTING - POWER SUPPLY

Hello, lovely people, it is another exciting beginning of the week, which means we get to learn about something new this week. My question for today is, have you ever wondered what keeps your computer running? The answer is the power supply, also known as the PSU. It might not be the most exciting part of a computer, but it is one of the most important.

So, what exactly does a power supply do?

It is likely that you already have an understanding of this, but I will still go ahead and answer the question. The power supply takes electricity from your wall outlet and converts it into the correct voltage that your computer components can safely use. Different parts of your computer, such as the motherboard, hard drive, and graphics card, require different amounts of power, and the PSU makes sure everything gets what it needs.

Today, I will take you through eight easy steps on how to install a power supply. If you are installing a PSU for the first time, don’t worry, it is very manageable if you take it step by step:

1. Turn Everything Off
Make sure your computer is completely powered off and unplugged from the wall.

2. Open the Case
Remove the side panel of your computer case using a screwdriver.

3. Remove the Old PSU (if replacing)
Disconnect all cables from the motherboard, drives, and other components, then unscrew and carefully remove the old power supply.

4. Position the New PSU
Place the new PSU into the designated slot (usually at the top or bottom of the case). Make sure the fan is facing the correct direction for airflow.

5. Secure It
Use screws to firmly attach the PSU to the case.

6. Connect the Cables

  • Plug the 24-pin cable into the motherboard
  • Connect the CPU power cable (4/8-pin)
  • Attach cables to storage drives (SATA)
  • Connect the graphics card if needed

7. Double-Check Connections
Make sure everything is securely connected and nothing is loose.

8. Close the Case and Power On
Put the side panel back on, plug in the power cable, and turn on your computer.

Sidenote: Sometimes your computer manuals also have the steps on how you can install the power supply

Installing a power supply might seem intimidating at first, but it’s actually one of the easier components to work with. As long as you follow the steps carefully and ensure all connections are secure, you will have your system up and running in no time. The PSU is the heart of your computer’s power system, so choosing and installing it properly is key to a stable and reliable setup.

I hope we all learned something new today. I am always excited to share these insights with you, and I look forward to seeing you in the next blog. As always, feel free to share this post so others can learn as well, and don’t hesitate to leave thoughtful comments or questions—I will be happy to respond!

  WEEK 2 - THE TRAITS OF A TECH As many of you may know from my previous post, I am currently studying IT at Bellevue University in a fully online program. After completing the first week of classes, I have gained a better understanding of the key traits a technology professional should possess—the essential dos and don’ts. I’ve also realized that these are fundamental principles that are often overlooked in the workplace. While these traits are important for IT professionals, they also serve as valuable ethical guidelines that can benefit any work environment. Let’s take a closer look at these traits. Honesty/Integrity My course materials define honesty as telling the truth and integrity as doing the right thing, and I strongly agree with both definitions. However, I believe honesty goes beyond being truthful to customers or supervisors—it also involves being truthful with yourself. Being honest with yourself requires self-reflection, such as putting yourself in others’ situations...
