Frequently Asked Questions

How do you make money?

Most of the links are Amazon Affiliates from SPLs tierlist since their group did the majority of the work gathering the data. I recommend using the links here instead of using PCPP to support them

Can I trust the recommendations?

The finder scrapes hundreds of powersupplies and compares them to thousands on SPLs PSU tierlist. This is a difficult process and many powersupplies have different variants with the exact same name so I recommend taking these results with a grain of salt.

Where did you get the tier ratings from and are you allowed to use them?

The tier ratings are from SPLs PSU tierlist more info about what these rankings mean are found over there.
I have been explicit given permission from SPL himself, with him saying "If you can find a way to aggregate the data without requiring edit access, sure."
