Selling my Intel Core i9-12900K — the flagship 12th Gen Alder Lake chip that's still a beast in 2026.

Why this CPU?

• 16 cores (8 Performance + 8 Efficiency) / 24 threads
• Boosts up to 5.2 GHz
• Hybrid architecture that handles gaming AND productivity without breaking a sweat
• LGA 1700 — compatible with Z690/Z790 boards, giving you an upgrade path
• Has integrated graphics (UHD 770) — unlike the KF, you can troubleshoot or run without a GPU
• No degradation issues like the 13th/14th Gen chips had — this generation is rock solid

This thing handles 1440p gaming, streaming, video editing, 3D rendering — whatever you throw at it. Pairs great with DDR4 or DDR5 depending on your board.

Pulled from a prebuilt I got in late 2022. Used on and off for about 2 years for gaming. Never overclocked, never abused. Thermal paste cleaned off, ready to drop into your build.

Ships in a clamshell case, well padded.

Asking $220 shipped / $200 local (Austin, TX)
