be quiet! SFX Power 3 300 300W

A 300W unit with 80+ Bronze efficiency certification and non-modular cabling. It uses the SFX form factor — confirm your case lists SFX support. 300W covers mainstream builds with a modest GPU. Skimping on the PSU is a false economy; better efficiency ratings usually mean better components and longer warranties.

Warranty coverage follows be quiet!'s standard policy — confirm regional terms on the listing. Scroll down for the complete spec table; the builder's compatibility checker will warn you about any conflicts with components you have already picked.
