Corsair HX750 Platinum 750W

This is a 750W unit with 80+ Platinum efficiency certification and full 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.

Its $385.64 price tag places it squarely in premium territory. Use the PlanMyPC system builder to verify it works alongside your other components and to watch live retailer pricing.
