Gigabyte GreenMax Plus 550W

This is a 550W unit with 80+ Bronze efficiency certification and non-modular cabling. 550W covers mainstream builds with a modest GPU. It uses the ATX form factor — confirm your case lists ATX support. 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. Warranty coverage follows Gigabyte'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.
