Buying a desktop PC: where to start
A desktop PC gives you more power for your money than a laptop, and it's easy to upgrade later. Every desktop computer for sale here is reviewed by our team before it goes live, whether it's a used PC from a private seller or a ready-built PC from AS Computers.
New, used or custom?
Used desktop PCs are the best value - often hundreds of pounds less than buying the same parts new. Ready-built PCs from AS Computers are tested and sold securely through us. A custom PC is built to your exact budget and what you'll use it for.
What to check before you buy
Look at the processor (CPU) and graphics card (GPU) first - they decide how fast a PC is for gaming and creative work. For most people, 16GB of memory and a 1TB SSD is the sweet spot. Our used gaming PC checklist covers everything else, and you can compare up to 3 PCs side by side.
Common questions
Is it safe to buy a used desktop PC?
Yes, if you check it first. Ask the seller questions through our private messages, see it working if you're collecting, and report anything that looks wrong - we'll look into it quickly.
Can I get a desktop PC delivered?
Many sellers offer UK delivery - look for "Delivery available" in the filters. Others offer collection, so you can see the PC before you pay.
What if I can't find the right PC?
Tell us what you'll use it for and your budget, and we'll recommend a desktop PC and build it for you.
