## Questions

**How much is a used B840 motherboard worth in the UK?**

Around £72. That is the median of 8 used B840 motherboard sales on eBay UK in the 60 days to 25 Oct 2026; half sold between £70 and £80.

**Is £70 a good price for a used B840 motherboard?**

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.

**How do I find a B840 below that price?**
