Amazon is set to roll out a new “Partfinder” tool which will check the compatibility of PC parts. The widget will show up on some PC component product pages where you will be able to select the brand and model number of your existing rig to check for compatibility.
The system has not been fully implemented yet, and we know that it only shows up on some product pages on the main Amazon webpage (the US one, i.e., dot com), and not dot in.
Popular PC components such as a few SSDs and GPUs have this feature enabled, including the Samsung 860 Evo SSD and GTX 1080. The Amazon Partfinder only seems to work for stuff that have model numbers, so basically, if you’re looking for replacements for laptops and pre-built PCs. At this stage, it’s of no help for those building their own rigs. However, you can still use it to check if two specific parts are compatible, like RAM and motherboards.
As with anything new that rolls out, there are bound to be some mismatches so even if you do check it out, not everything might be accurate. What we can tell you for sure though, is that at its current stage, you’re still better off using a third party tool like PC Part Picker or something to check for compatibility if building your own rig.
