How we filter
Every feed has its own filter, tuned by hand for this one part. Before any change goes live, those filters are tested against thousands of real eBay listing titles. Every night, each feed is checked against every other deal page in its category, so a listing for a different part that slips in gets flagged and fixed instead of quietly shown.
Of the 71 listings we observed for this game in the last 30 days, we filtered out 37 of 71 (~52%) for quality reasons. The remaining 34 are what we'd actually surface.
- 31 matched a bootleg / out-of-scope keyword
- 3 seller had too few feedback ratings
- 2 priced above the curated ceiling
- 1 caught by a junk-listing guard
What the feed excludes
An eBay search for Core i5-12400 returns far more than the part itself: laptop chips, mining rigs, coolers, empty boxes and whole PCs all mention it in their titles. These are the 64 terms we filter out to keep this feed to the real thing. A listing whose title contains any of them never reaches the feed, the price table or an alert. Many look unrelated to Core i5-12400 because they are: that's the noise.

Core i5-12400: buyer & reseller spec sheet
Exact SKU identity. This page is the plain i5-12400, which includes integrated graphics. The Core i5-12400F is a separate SKU without them, and the low-power 12400T is a different part again. Confirm the suffix from the marking on the heat spreader in the photos rather than the title. The socket is LGA 1700.
Variants & value impact. Boxed retail copies (BX-prefixed model numbers) usually carry a higher asking price than tray/OEM copies (CM-prefixed model numbers). Open-box and loose used chips are generally the cheapest routes in.
Listing traps. Searches for this chip are full of pre-built PCs and motherboard listings that name the CPU in the title, and the feed filters those out. Some listings use the 12400 name for a different chip, so check the marking and the model number in the photos. Many listings name a specific motherboard in the title; board and memory support depend on the board you pair it with, so check your own board's spec page.
Buying a used processor: what to check
These checks apply to every processor on our CPU pages. The item notes above cover what is specific to this model.
Used
- Ask for a clear, close photo of the pins or contact pads, wherever the socket keeps them. Bent pins are the most common failure.
- Confirm the model printed on the heat spreader matches the listing, and ask for a screenshot of the chip identified in the OS or BIOS.
- Ask whether it was overclocked or delidded. Neither is a dealbreaker, but both should be disclosed.
Refurbished
- Find out who tested it and what the return window is.
New
- Check whether it is a boxed retail chip or a tray chip. Tray chips usually ship without a cooler and with a different warranty.
