SeaSonic M12II 380W

This is a 380W unit with 80+ Bronze efficiency certification and non-modular cabling. It uses the ATX form factor — confirm your case lists ATX support. 380W covers mainstream builds with a modest GPU. Power supplies are the wrong place to cut corners — efficiency certification correlates with build quality and warranty length.

Drop it into the PlanMyPC builder to check compatibility with the rest of your parts and compare current power supply prices across retailers. 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.
