SeaSonic M12II 430W

This is a 430W unit with 80+ Bronze efficiency certification and non-modular cabling. 430W covers mainstream builds with a modest GPU. It uses the ATX form factor — confirm your case lists ATX support. Skimping on the PSU is a false economy; better efficiency ratings usually mean better components and longer warranties.

Drop it into the PlanMyPC builder to check compatibility with the rest of your parts. Support and warranty service run through Seasonic, with terms that vary by region. Scroll down for the complete spec table; the builder's compatibility checker will warn you about any conflicts with components you have already picked.
