CoolMax RM-750B 750W

A 750W unit with 80+ efficiency certification and non-modular cabling. 750W covers a 220–300W GPU and a midrange CPU comfortably. It uses the ATX form factor — confirm your case lists ATX support. A dependable power supply protects everything downstream, and efficiency tiers are a decent proxy for overall build quality.

Expect to pay around $54.99, which lands it among budget options. Use the PlanMyPC system builder to verify it works alongside your other components and to watch live retailer pricing.
