- Power Supply: Calculate the wattage required for your components using an online PSU calculator.
- Physical Fit: Ensure your case supports the size of your motherboard (e.g., ATX, Micro-ATX) and GPU length.
- Memory Compatibility: Confirm that your RAM matches your motherboard’s specifications (DDR4 vs. DDR5).
Step-by-Step Guide to Building a PC
1. Gather Your Tools
- Phillips-head screwdriver
- Anti-static wrist strap
- Cable ties for organization
2. Assemble the Components
- Install the CPU on the motherboard.
- Attach the CPU cooler (air or liquid).
- Install RAM in the appropriate DIMM slots.
- Secure the motherboard into the case.
- Connect the power supply and route cables.
- Install the GPU and storage drives.
3. First Boot Setup
