EVGA 450 B3 450W

This is a 450W unit with 80+ Bronze efficiency certification and full cabling. 450W 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.

Its $139.99 price tag places it squarely in high-end territory. Use the PlanMyPC system builder to verify it works alongside your other components and to watch live retailer pricing. Support and warranty service run through EVGA, with terms that vary by region. Every published spec is tabulated below, and compatibility against your current part list is checked automatically.
