GameMax GP 500W

This is a 500W unit with 80+ Bronze efficiency certification and non-modular cabling. 500W 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.

Use the PlanMyPC system builder to verify it works alongside your other components. Support and warranty service run through GameMax, 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.
