Second-hand hardware

Used PC parts buying guide.

Used GPUs, CPUs and motherboards can be good value, but the risk is different for every category. The safest listings prove the exact model, show the real item, include working tests and leave enough price gap versus buying newer hardware.

Start with the exact model, not the headline

Listing titles are often incomplete. A seller may write only “RTX 3060” or “Ryzen 7” even though the value depends on the VRAM version, board partner, cooler, CPU socket, chipset support or included accessories.

  • For GPUs, confirm VRAM amount, memory type, cooler model and power connector layout.
  • For CPUs, confirm the exact suffix, socket, supported chipset and whether the motherboard BIOS supports it.
  • For motherboards, confirm chipset, revision, socket condition, I/O shield, Wi-Fi antennas and included mounting hardware.

Proof to ask for before paying

PhotosReal item photos

Ask for close photos of labels, ports, sockets, PCIe fingers and power connectors.

TestingRecent working proof

Request a timestamped boot screenshot, benchmark run or BIOS screen from the exact part.

ValueCompare alternatives

Check nearby models before buying. A cheap older card can be worse value than a newer efficient one.
