Around £20. That is the median of 54 used Intel Core i5-8400 sales on eBay UK in the 60 days to 25 Oct 2026; half sold between £20 and £25.

**Is £20 a good price for a used Intel Core i5-8400?**

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.
