How we rank
Best 80 PLUS efficiency rating first, then fully modular over semi-modular over fixed cables (a unit listed only as "modular" counts as semi-modular, because the listing does not say which), then more watts, then the cheaper unit. Units without a readable 80 PLUS rating are left out.
Only power supplies with a photo, a full spec table and a new, in-stock price read in the last two weeks are considered, so a part that is sold out everywhere drops off until a shop has it again. Refurbished and used stock is left out. Prices change through the day: check the shop before you buy. We may earn commission when you buy through a link on a product page; it never changes the order here.
