A PC builder is an online tool that lets you choose a processor, motherboard, RAM, graphics card, storage, power supply and case, and warns you when two parts will not work together. Most popular PC builder sites are made for the US or Europe. Their prices are in dollars, their shops do not deliver here, and half the parts they suggest are not even sold in Sri Lanka.
The PCGuide.lk PC Builder was built to fix that. It only shows parts Sri Lankan shops actually stock, with prices in LKR, so the build you plan is a build you can buy this week.
Why use a PC builder instead of asking a shop?
Shops are helpful, but every shop builds around its own stock. If one shop has too many B760 boards, you will probably be offered a B760 board. A PC builder puts you in control:
- Compatibility checks — CPU socket vs motherboard, DDR4 vs DDR5 RAM, GPU length vs case size, cooler height vs case clearance.
- Local prices side by side — compare the same part across shops instead of calling five of them. See our guide to PC parts price comparison in Sri Lanka.
- Power check — the total wattage feeds straight into the PSU Calculator, so you do not under-buy the power supply.
- A shareable parts list — send it to a friend or a shop on WhatsApp and get a quote for the exact list.
How to use the PCGuide.lk PC Builder (step by step)
- Set your budget and purpose. Gaming, editing, office or a home server each need a different balance of parts.
- Pick the CPU first. The processor decides the socket, which decides the motherboard.
- Choose a compatible motherboard. The builder only shows boards that fit your CPU socket.
- Add RAM. Match the memory type (DDR4 or DDR5) to the board. 16 GB is the minimum for gaming today; 32 GB for editing.
- Choose the graphics card. For gaming this is where most of the budget should go.
- Add storage. An NVMe SSD for Windows and games; add a hard drive later for bulk files.
- Run the PSU check. Pick a power supply with 20–30% headroom over the calculated load.
- Pick a case that fits the GPU length and cooler height.
- Compare shop prices and send the list to the shop with the best total.
Common PC builder mistakes Sri Lankan buyers make
- Spending on an expensive CPU and pairing it with a weak graphics card for gaming.
- Buying a cheap, unbranded power supply to save a few thousand rupees.
- Choosing a motherboard without checking whether it needs a BIOS update for a newer CPU.
- Forgetting the cost of Windows, a monitor, keyboard and mouse.

Can I use a PC builder for second-hand parts?
Yes. Many Sri Lankan builds mix new and used parts, especially used graphics cards. Plan the build in the PC Builder, then check the used market on PCGuide.lk Buy & Sell. Always run the PSU check, because older GPUs often draw more power than newer ones.
