🛒 Other Places to Find Used Gaming PCs in Singapore
Carousell — The #1 marketplace for secondhand electronics in Singapore. Thousands of individual and shop listings with full specs, photos, and buyer reviews. Always meet in person to test before buying.
HardwareZone Buy/Sell/Trade forums — Beloved by PC enthusiasts who post full build specs, benchmark results, and receipts. Generally higher-trust sellers who know their hardware well.
Facebook Marketplace — Good for deals from individuals upgrading their rigs. More negotiation room, but do your due diligence on the seller.
Sim Lim Square — Still the go-to physical destination for PC parts and electronics. Several shops carry secondhand and refurbished desktop components and complete systems.
✔️ What to Check Before Buying
Always test in person if possible. Run a game, open HWiNFO64 to check temps, and verify all ports and drives are recognised. A 30-minute session tells you more than any listing description.
- GPU condition — Avoid cards used for crypto mining; check for excessive fan wear. Respawn.sg flags mining history on all listings.
- Storage health — Use CrystalDiskInfo to verify SSD/HDD health above 90%.
- RAM speed — Confirm XMP/EXPO is enabled and RAM runs at its rated speeds in BIOS.
- PSU brand — Stick to Corsair, Seasonic, be quiet!, or EVGA units.
- CPU thermals — Run Prime95 briefly; sustained temps above 90°C at stock is a red flag.
- Warranty — Ask for original receipts; some component warranties are transferable.
