💡 The Building Process: Step by Step
1. Prepare Your Workspace
- Clean, static-free surface
- Good lighting and room to spread out
2. Install the CPU
- Open the socket latch on the motherboard
- Align CPU arrow with socket corner and gently place it in
- Lock it down
3. Install RAM and Storage
- Insert RAM into DIMM slots (use paired slots if dual-channel)
- Plug M.2 SSD into its slot, or mount a 2.5″ SSD
4. Mount Motherboard into the Case
- Install standoffs if your case doesn’t have them pre-installed
- Line up rear I/O shield
- Screw motherboard to case
5. Install PSU and Connect Power
- Mount PSU in the case (bottom/rear)
- Connect:
- 24-pin ATX cable to motherboard
- 8-pin CPU power cable
- SATA cables to drives
- PCIe cables to GPU (if needed)
6. Install GPU (if using one)
- Slot GPU into top PCIe x16 slot
- Screw into rear bracket
- Connect power cables if required
7. Connect Case Cables
- Power switch, reset, front USB, audio
- Follow motherboard manual for pin layout
8. Double-Check Everything
- Cables secure?
- No loose screws?
- RAM/GPU seated properly?
9. Boot It Up!
- Plug into a monitor and keyboard
- Turn on the PSU and press power
- Enter BIOS (
DELorF2) to verify hardware
🧠 Tips for Your First Build
- Don’t force anything! If a part doesn’t fit, double-check orientation
- Take breaks if you get stuck
- Cable management makes a huge difference in airflow and looks
- Document your build (you’ll thank yourself later!)
