Buying a Used Desktop PC: What to Check

A fair price for a desktop PC in good condition is around £65 to £325 (approximately $87 to $433), against £100 to £500 across the full condition range. Desktops are valued on their components, and buyers price the parts individually before deciding what the whole is worth.

What a fair price looks like

Condition on WishThrift is described by the seller against five grades, and nobody inspects it on your behalf — so the description and the photographs are what you are buying on.

Condition	Typical	What it means
New with Tags	£500 (~$666)	Unused, tags or seals intact
Like New	£425 (~$566)	Barely used, no visible wear
Good	£325 (~$433)	Light signs of use, complete and working
Fair	£225 (~$300)	Heavily used, or a described fault or missing part
For Parts	£125 (~$167)	Not working or incomplete, sold as seen

Sterling guide ranges with an approximate US dollar equivalent at £1 ≈ $1.33 (July 2026). Sellers set their own asking price; these are a starting point for judging an offer. All five grades explained.

The checklist before you pay

An account lock is the single biggest one — a device still signed in to an iCloud, Google or Microsoft account cannot be reset and is effectively unusable. After that, battery health and undisclosed third-party repairs.

Run through these before money changes hands — they are the things that decide whether a desktop PC is worth what is being asked:

Old processors on dead socket platforms
Mechanical hard drives only
Proprietary office machines that cannot be upgraded
Dust-clogged interiors and failing fans

And the things worth paying more for, because they hold their value:

Recent processors with an upgrade path
Discrete graphics cards rather than integrated
SSD storage and 16GB or more of memory
Cases with room and airflow for upgrades

Common faults and fakes

Outright counterfeits are rare outside accessories, where fake chargers and cables are a genuine fire risk. The commoner problem is a device described as working that has a fault the seller knows about.

Ask the seller to factory reset and remove their account BEFORE you pay, and to send a photograph of the settings screen showing it signed out. Ask for the exact model identifier and, on anything with a battery, the battery health figure.

WishThrift does not authenticate, inspect or grade anything, and no marketplace check replaces your own. If a seller will not answer a direct question about condition or origin, that is the answer.

Questions to ask the seller

These are the three that get asked most often about a desktop PC, and the answers tell you most of what you need:

“What are the full specs?”

List every component by model. Buyers price a PC by summing the parts, so vagueness costs you money directly.

“Does it have a graphics card?”

Say dedicated or integrated and name the card. It is the difference between an office machine and a gaming one.

“Is Windows activated?”

Check and say. A genuine activated licence saves the buyer a real cost and is worth stating.

Also worth establishing before you commit:

List the exact processor, graphics card, memory and storage
Confirm the machine posts and runs stably
Clean the interior and photograph it

Photographs to ask for

If the listing does not already show these, ask — a seller who has the item will send them in minutes:

The tower from the front and side
The interior with components visible
The system information screen showing processor and RAM
The rear I/O, plus any included keyboard, mouse or cables

Details to confirm before you commit

Processor model, RAM amount and speed, storage type and size
Motherboard, power supply wattage and case size
Whether it has a dedicated graphics card, and which
Whether Windows is installed and activated, and what peripherals are included

When to buy

Steady with lifts in September and before Christmas. Machines with recent processors and an SSD sell quickly; older mechanical-drive systems sit.

Prices move against that cycle for a buyer: the cheapest time to buy is when sellers are listing most, not when demand peaks.

Paying and collecting safely

WishThrift does not process payments, hold funds or offer buyer protection — you agree the price and the method with the seller directly, which is what keeps the platform free on both sides. Meet somewhere public where you can, inspect before you pay, and keep the conversation on the site so there is a record of what was agreed. Be wary of any seller who wants to move the conversation elsewhere before you have agreed anything.

Selling one instead?

If you already have a desktop PC sitting unused, it is free to list and there is no commission — the price you agree is the amount you keep. Read how to sell desktop PC for what to photograph and how to price, or what desktop PC is worth at each condition grade.

Frequently asked questions

What should I pay for a used desktop PC?

Around £65 to £325 in good condition, more for barely-used examples and less for anything with a described fault. Compare against the seller’s photographs rather than the grade alone.

How do I check a desktop PC before buying?

Is buying a desktop PC second hand safe?

Yes, with the ordinary care any private sale needs. WishThrift does not authenticate, inspect or hold funds, so inspect before you pay where you can, meet somewhere public, and keep the conversation on the site. An account lock is the single biggest one — a device still signed in to an iCloud, Google or Microsoft account cannot be reset and is effectively unusable. After that, battery health and undisclosed third-party repairs.
