Around £198. That is the median of 15 used Intel Core i9-12900K sales on eBay UK in the 60 days to 25 Oct 2026; half sold between £182 and £200.

**Is £182 a good price for a used Intel Core i9-12900K?**

It is cheaper than three in four recent sales. A price far below that is more often a fault, a missing part or a scam than a bargain, so check the photos and the seller, and see it working before you pay.
