be quiet! Pure Power 13 M 550W

A 550W unit with 80+ Gold efficiency certification and full cabling. It uses the ATX form factor — confirm your case lists ATX support. 550W 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.

Expect to pay around $155.05, which lands it among high-end options. PlanMyPC's builder flags compatibility problems automatically and tracks the latest power supply deals from multiple stores. 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.
