What Should I Check Before Turning on a PC Build?

There are several components of a PC that you should check before turning it on. These include the power supply, the RAM, the Case, and the cables. If they are not functional, the PC build will not function properly. The power supply should be able to power the PC and run programs. The monitor, keyboard, and mouse should work correctly. A non-functioning keyboard and mouse can ruin a PC build.

Power supply

Before you turn on your PC build, you must ensure it has a functioning power supply. The type of power supply you purchase will determine its form factor, size, connector types, and other essential details. It would help if you also considered its efficiency, saving you money on your electric bill.

The power supply is one of the essential parts of your computer because it provides the electricity needed to power all the other parts. Buying a cheap power supply can ruin the components inside your computer, so choose a high-quality one. The correct power supply will ensure your computer’s stability for many years.

The power supply controls your PC’s temperature and fan speed. It also supplies the +12V rail, which provides 95% of your PC’s power. If you want more control, opt for the AXi series, which offers more monitoring features. This series can monitor the internal temperature and the +12V and +3.3V rails.

You’ll want to choose a power supply with an ATX connector. The ATX connector is used to connect the power supply to your motherboard. This connector is a good choice because it reduces the number of wires in the motherboard, which can interfere with airflow and cooling.


RAM, also known as random access memory, is an integral part of any computer. It provides fast access to data and serves as a temporary storage medium between the processor and permanent data storage. The more RAM a PC has, the quicker it will perform. To check if your PC has enough RAM, go to the Start menu and click on the Computer icon. Right-click the icon to get the properties menu. Click the Memory tab to find out the amount of RAM installed on your PC.

RAM is one of the most critical computer components, and upgrading it can make your PC run snappier. Many older PCs only have two or four gigabytes of RAM, which can be quickly used up when you open multiple tabs in Chrome or have too many programs on the desktop.

If you are building a gaming PC, you will want the fastest and most potent components possible. While the CPU and graphics card is essential, you should also consider the other parts of your PC, such as the storage drives and the RAM. Some gamers might need as much as 16GB of RAM, while others may need more.


Before turning on a newly constructed PC, there are a few things you should look for. First, make sure the motherboard and front panel cables are correctly connected. Ensure that the screws and socket clips are securely fastened. Also, be sure the motherboard is installed correctly in the case. If the motherboard and front panel cables are not connected, there’s a good chance that one or both components could have been accidentally moved during the installation process.

Another essential thing to consider is the form factor of your motherboard. Ensure the motherboard fits the case and that all the other components work properly. An excellent guide to check for compatibility is the case’s spec sheet. If everything looks correct, turn on your PC.

Everything should go smoothly if you’ve followed the steps in the guide. Make sure the motherboard lights and fans are working. It would help if you also double-checked the connections on your power supply. Loose cables can prevent your PC from powering on.


If you are planning to build your PC, there are specific cables you must ensure are correctly connected. These cables are necessary for data transfer as well as for electrical power. They should be attached safely, so they do not get tangled with fans or touch hot surfaces. Zip ties are a great option to secure cables. Proper wiring prevents potential damage and ensures that buttons, LEDs, and audio connections work correctly.

Before turning on your PC, check to ensure all cables are correctly connected. If any wires are loose, they could cause your PC to malfunction. This is especially important if you’ve installed a modular power supply, which allows you to choose which cables you want. Similarly, if you’re connecting two hard drives, you should check to ensure the power cables on each drive are correctly connected.

You should immediately contact the system manufacturer if there are any loose or malfunctioning cables. Opening a prebuilt PC could void the warranty, so follow all steps carefully.

Mounting a motherboard

Mounting a motherboard is an essential step in building a PC. To do this, you must first install all the core components. These include the CPU, RAM modules, and M.2 SSD. Then, you can mount the motherboard. To do this, you will need a Philips head screwdriver.

Before mounting the motherboard, you should put it on a nonmetal work surface. Make sure the screw holes are lined up with the standoffs. Then, screw the motherboard into the case. Make sure you tighten the screws in a star pattern and don’t over-tighten the screws. If there are any loose screws, they could damage the motherboard.

Before turning on your new computer, you should test all connections. Check that the processor is seated correctly, and ensure you’ve properly installed the power connector. It would help if you connected the front USB ports to the motherboard’s connectors. The front USB ports are usually labeled. Make sure you use the correct plugs for the appropriate pins.

Next, you must ensure the memory and graphics processing unit are installed correctly. The graphics processing unit (GPU) is an essential component of your PC. It allows it to perform complex graphics calculations. Most CPUs have integrated graphics, but it’s necessary to have a graphics processor if you want to enjoy the best PC gaming experience.

Installing a CPU

When installing a CPU, align it properly in the socket. It’s essential to line up the top and bottom of the CPU with the socket cover to ensure a good fit. Failure to do so can result in damaging the chip and the board. The CPU should be seated gently into the socket, and you don’t want to force it into it.

Generally, all the computer components that you purchase should have instructions. For example, a CPU has a manual showing you how to install it. It’s also helpful to consult a motherboard manual when installing a CPU. Using a manual can help you make the process less intimidating.

You can also use the CPU’s hardware to check temperatures. You can adjust fan curves or check thermal paste if temperatures are too high. If temperatures are too low, you can narrow your cooling system. After all, you want your PC to run smoothly and be free of errors.
