GameMax GM 300W

This is a 300W unit with 80+ Bronze efficiency certification and non-modular cabling. It uses the ATX form factor — confirm your case lists ATX support. 300W 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.

At $114.00 it sits in the high-end power supply bracket. Use the PlanMyPC system builder to verify it works alongside your other components and to watch live retailer pricing.
