It’s vital to choose RAM that is compatible with your motherboard and CPU.
Power Supply and Storage
When selecting a power supply unit (PSU), it’s essential to consider factors such as wattage, efficiency rating, and modular vs non-modular design. The wattage of the PSU should be sufficient to power all of your components, with some headroom for future upgrades. An efficiency rating of 80 Plus or higher indicates that the PSU is more energy efficient. A modular design allows you to only use the cables you need, reducing clutter inside your case. Choosing the right storage drives is also important for ensuring that your system has enough storage space and performs well. SSDs are faster than HDDs, but typically have less storage capacity for the same price. It’s common to use a smaller SSD for your operating system and frequently used programmes, and a larger HDD for storing files and less frequently used programmes.
Assembling the Motherboard
Assembling the motherboard is a crucial step in building a computer system. The first step is to install the CPU into the CPU socket on the motherboard. This typically involves lifting a retention arm on the socket, aligning the CPU with the socket keying, and gently lowering it into place.
Once the CPU is installed, you’ll need to apply thermal paste to the top of the CPU before attaching a heatsink and fan to keep it cool. Next, you’ll need to install the RAM into the memory slots on the motherboard. This typically involves opening retention clips on each side of the slot, aligning the notch on the RAM stick with the keying in the slot, and firmly pressing down until the retention clips click into place.
It’s important to install the RAM in the correct slots according to your motherboard’s manual in order to enable dual-channel memory mode for improved performance. After installing the CPU and RAM, you’ll need to install any additional components such as a graphics card or sound card into their respective expansion slots on the motherboard. This typically involves removing expansion slot covers from the case, aligning the card with the slot, and firmly pressing down until it clicks into place.
It’s important to secure any additional components with screws or retention brackets to prevent them from coming loose during use.
Installing the CPU and RAM
Installing the CPU and RAM is a critical step in building a computer system. The CPU, or central processing unit, is responsible for performing all of the calculations and processing tasks in a computer. To install a CPU, you’ll need to first locate the CPU socket on the motherboard.
This socket will have a lever or retention arm that needs to be lifted in order to open it. Once you’ve opened the CPU socket, you’ll need to carefully align the notches on the CPU with the corresponding keys in the socket. It’s important to handle the CPU carefully by its edges and avoid touching any of its pins or contacts.
Once aligned, you can gently lower the CPU into place and secure it by lowering the retention arm back down. After installing the CPU, you’ll need to install the RAM into its memory slots on the motherboard. Most motherboards have multiple slots for RAM, typically in pairs for dual-channel memory mode.
