## Questions

**How much is a used 300W power supply worth in the UK?**

Around £14. That is the median of 80 used 300W power supply sales on eBay UK in the 60 days to 25 Oct 2026; half sold between £10 and £21.

**Is £10 a good price for a used 300W power supply?**

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 300W PSU below that price?**
