EVGA SuperNOVA 550 GM 550W

A 550W unit with 80+ Gold efficiency certification and full cabling. 550W covers mainstream builds with a modest GPU. It uses the SFX form factor — confirm your case lists SFX support. Skimping on the PSU is a false economy; better efficiency ratings usually mean better components and longer warranties.

Its $259.00 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. Support and warranty service run through EVGA, 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.
