First PC Build Checklist: Parts, Tools and Preparation

1. Define what the finished computer must do

Start with the software you want to run, your monitor and the devices you will keep. Then label each purchase as already owned, included or still needed. Remember the screen, keyboard, operating-system licence and delivery costs if they fall within the same budget. Use full product names on the list. A missing Wi-Fi or memory-generation suffix can mean the box that arrives is different from the product you planned around.

2. Account for the core components

A conventional desktop needs a compatible CPU, motherboard, RAM, system drive, PSU, case and CPU cooler. To omit a separate GPU, the CPU must provide usable integrated graphics and the board must have a suitable output. Check what is actually included with each product: not every retail processor comes with a cooler, and a photo showing antennas may belong to a Wi-Fi variant you did not select. Add case fans, networking and audio equipment only where the chosen parts leave a need.

3. Count the small parts before opening everything

Sort the accessory bags before mounting anything. Find the motherboard standoffs, case screws, correct cooler brackets, SSD screw or latch, and SATA data cables if needed. Check whether the cooler has pre-applied paste. Keep the new PSU's cables together and old PSU cables elsewhere so they cannot be mixed. A quick photo of each bag's contents helps track a misplaced spacer. If something is absent, identify its specified thread and length before ordering a replacement.

4. Prepare tools and a suitable work area

Clear a stable, well-lit table with enough room to lay the case on its side. Most mainstream builds need a suitable Phillips screwdriver, a screw tray, a light and cable ties; small SSD screws may need a smaller driver. Set out any specialty tool supplied with the parts. Keep drinks away, handle boards by the edges and take appropriate antistatic precautions. Avoid carpeted work areas and keep mains power disconnected while fitting components. The PSU enclosure stays closed.

5. Prepare the first boot and installation kit

Have a monitor, the right video cable and a keyboard ready for the first start. Prepare a way to get online, plus the motherboard's network driver on a separate USB drive if needed. For Windows 11, follow Microsoft's official media-creation instructions and current hardware requirements. Use an empty USB drive for the installer—the creation process erases it. Download the manuals onto another device so you can read them before the new PC has an operating system.

6. Perform a final readiness review

Compare the delivered labels with the parts list and inspect for damage. Open the motherboard manual to the memory-slot and front-panel diagrams, with the cooler instructions nearby. Check that each compatibility warning now has an answer. Keep receipts, packaging and socket covers until the PC has been tested. A missing bracket is worth stopping for; improvised mounting is not a shortcut. With the kit complete, move to assembly and first-boot checks before tuning performance.

Your checklist

• Every required part is present and its exact model matches the list.
• Cooler mount, SSD retention hardware and case screws are accounted for.
• The display cable has a working graphics output to connect to.
• Official installer, network access and manuals are ready.
• Unresolved compatibility or delivery issues have been dealt with.
