Questions
How much is a used 400W power supply worth in the UK?
Around £16. That is the median of 46 used 400W power supply sales on eBay UK in the 60 days to 25 Oct 2026; half sold between £11 and £26.
Is £11 a good price for a used 400W 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 400W PSU below that price?
