Price alerts for the parts of your build

Building or upgrading a PC? The cheapest way to buy used parts is to be first to the listing that is under the usual price. PathAu Build does the watching: you name the part and your price.
How it works
- Pick the part — a graphics card, processor, memory, storage, board, power supply — or a whole PC with the card you want.
- Say the most you'll pay. Every part page shows what it usually sells for used, so you know if your price is realistic.
- We check new listings on eBay UK, Gumtree and Vinted and ping you the minute one matches.
Typical used prices for every part: used PC part prices.
