Building your own PC for the first time is one of the most rewarding technology projects you can take on. You end up with exactly the machine you want, at better value than any prebuilt, and with complete knowledge of every component inside it. The process is less intimidating than it appears online.
Before You Start: Parts Compatibility
The most important preparation: confirm your parts are compatible before purchasing. The key compatibility requirements:
- CPU socket must match motherboard socket (e.g., LGA1700 CPU needs LGA1700 motherboard)
- RAM type must match motherboard support (DDR4 or DDR5)
- Case size must support your motherboard form factor (ATX, mATX)
- PSU wattage must cover your total system draw with 30% headroom
The Build Order
- Prepare the case: Remove panels, install any included fans
- Install CPU: Handle by the edges, align the triangle markers, gently seat — it drops in without force. Lower the retention mechanism.
- Apply thermal paste: Pea-sized dot on the CPU centre
- Install CPU cooler: Follow the cooler's specific instructions. Backplate, standoffs, then cooler mounting
- Install RAM: Check the motherboard manual for recommended slots (usually A2 and B2 for dual-channel)
- Install SSD(s): M.2 into the appropriate slot, screw down. SATA SSDs cable-connect later.
- Mount motherboard in case: Use the included standoffs and screws. Do not over-tighten.
- Install GPU: Into the top PCIe x16 slot. Ensure the retention clip locks.
- Install PSU: Cable connections for CPU power (4+4 pin near CPU), GPU power, motherboard 24-pin
- Cable management: Route cables behind the motherboard tray where possible
- First power-on: Before installing the OS, enter BIOS (usually Delete key) and verify all components are detected
Nigeria-Specific Preparation
Build on a hard surface, not carpet (static electricity). Have a UPS ready before powering on for the first time — a sudden power cut during OS installation can corrupt the installation. Keep the case in a location with adequate airflow.
